A solar cell is a device which changes sunlight into electricity. En solcelle er en indretning, som ændrer sollys til elektricitet. A more technical term for a solar cell is a photovoltaic cell. En mere tekniske betegnelse for en solcelle er en solcelle. The term “photo” derives from the Greek word for “light,” and the term “voltaic” comes from the word “volt” which means “electrical force.” A “cell” is a small receptacle or container containing electrodes which generate power. Udtrykket "photo" stammer fra det græske ord for "lys" og udtrykket "voltaic" stammer fra ordet "volt" som betyder "elektrisk kraft." A "celle" er en lille beholder eller container, der indeholder elektroder, der producerer strøm . Thus, a photovoltaic cell is a container that creates electric force, through light. Således er en fotovoltaisk celle er en beholder, der skaber elektrisk kraft gennem lys. Whereas a solar cell can generate electricity from any light source, its intended use is the collection of solar energy from the sun. Der en solcelle kan generere elektricitet fra enhver lyskilde, den påtænkte anvendelse, er indsamling af solenergi fra solen.

How a Solar Cell Works Hvordan en solcelle virker

The solar cell works as follows: Photons (which are particles of light in sun rays) hit the surface of the solar cell and are absorbed a semiconductor, such as silicon. Solcellen fungerer som følger: fotoner (som er partikler af lys i solens stråler) ramte overfladen af ​​solcelle og absorberes en halvleder, såsom silicium. These photons (bits of sunlight) knock electrons loose from the atoms inside the semiconductor. Disse fotoner (bits af sollys) banke elektroner løs fra atomer inde i halvlederindustrien. The photons then push the electrons along, leaving a “gap” in the atom. Fotonerne derefter skubbe de elektroner langs, hvilket efterlader en "hul" i atomet. Another electron is then pulled from an adjacent atom to fill the gap. En anden elektron er derefter trukket fra en tilstødende atom at udfylde hullet. And so an electrical flow is generated. Og så en elektrisk strøm er genereret.

The simplicity of this is that one atom has an extra electron, and the other atom is missing one. Enkeltheden af ​​dette er, at ét atom er et ekstra elektron, og den anden atom mangler en. This is referred to as a “difference in potential.” Nature, wanting to remain balanced, tries to even things out by pulling another electron from the neighboring atom. Dette kaldes en "forskel i potentiale." Nature, der ønsker at forblive afbalanceret, forsøger at selv ting ud ved at trække en anden elektron fra den nærliggende atom. A solar panel is comprised of a group of solar cells which are linked together to produce the desired amount of electrical energy. En solfanger består af en gruppe af solceller, som er bundet sammen til frembringelse af den ønskede mængde af elektrisk energi. A group of solar cells linked together can also be referred to as a “module.” Thus the terms “solar panel,” and “solar module,” are synonymous to each other, and essentially mean the exact same thing. En gruppe af solceller bundet sammen også kan omtales som en "modul". Således udtrykkene "solpanel" og "solcelle," er synonyme med hinanden, og i det væsentlige betyder nøjagtigt det samme. “Solar panel” is the more common term, and “solar module” is the technical term. "Solar panel" er den mere almindelige udtryk, og "sol-modulet" er den tekniske term.

One can use solar panels individually or one can link several together in order to generate more electricity. Kan man anvende solpaneler individuelt eller man kan forbinde flere sammen for at generere mere elektricitet. When a group of solar panels are linked together, it is called a “solar array”. Når en gruppe af solpaneler er koblet sammen, kaldes det en "solpanel". The more solar panels are included in a solar array, the more power they produce. De mere solpaneler indgår i en solpanel, jo mere strøm de producerer. Solar Power is a clean and virtually unlimited source of energy. Solar Power er en ren og næsten ubegrænset energikilde. I say “virtually unlimited” because the sun itself won't last forever. Jeg siger "næsten ubegrænset", fordi solen ikke selv vil vare evigt. But we won't have to worry about that for the next few billion years. Men vi vil ikke have at bekymre sig om, at for de næste par milliarder år. Since solar power is a clean energy source which has been around for decades, one might wonder why its not used more. Da solenergi er en ren energikilde, der har eksisteret i årtier, kan det undre, hvorfor det ikke bruges mere. The answer to this lies partially in the cost of producing solar panels, as well as in the efficiency of the solar panels. Svaret på dette ligger delvist i omkostningerne til fremstilling af solpaneler, såvel som i effektiviteten af ​​solpaneler.

We are currently in the second generation of solar panel technology and verging on the third. Vi er i øjeblikket i anden generation af sol-panel teknologi og på kanten af ​​den tredje. A lot has changed since the first generation. Solar panels a are becoming a viable source of clean energy. Meget har ændret sig siden første generation. Solpaneler en er ved at blive en levedygtig kilde til ren energi. The solar cells of earlier times were relatively large and bulky compared to our current models. De solceller tidligere tider var forholdsvis store og pladskrævende i forhold til vores nuværende modeller. In view of the amount of energy and material required to produce them, and the amount of energy they actually produced, it was more costly to use solar energy than to use fossil fuels. I betragtning af den mængde energi og materialer kræves for at fremstille dem, og mængden af ​​energi, de faktisk producerede var det dyrere at anvende solenergi end at anvende fossile brændstoffer. The only exception was in places where little or no fossil fuels were available, such as in space. Den eneste undtagelse var på steder, hvor lidt eller ingen fossile brændstoffer var tilgængelige, såsom i rummet.

With the second-generation solar cells, we attempted to tackle this exact problem. Med anden generation af solceller, forsøgte vi at løse netop dette problem. We attempted improve manufacturing techniques so as to reduce the costs, materials and energy needed for the production of solar cells. Vi forsøgte at forbedre teknikker til fremstilling, således at reducere de omkostninger, materialer og energi er nødvendig for produktionen af ​​solceller. Recently, major advances have been made in the production of solar cells, which have reduced production costs. For nylig har store fremskridt i fremstillingen af ​​solceller, der har reducerede produktionsomkostninger. One contribution in this area was the development of techniques to coat glass or ceramic materials with very thin layers of semi-conductive substances. Et bidrag på dette område var udviklingen af ​​teknikker til at coat glas eller keramiske materialer med meget tynde lag af semi-ledende stoffer. This made it possible to produce solar panels using only a fraction of the semi-conductive material that was required earlier. Dette gjorde det muligt at fremstille solpaneler kun anvender en del af halvledende materiale, som var påkrævet før.

The production of solar panels using this second-generation technology is referred to as “Thin Film Technology.” Third-generation solar energy technologies are currently being researched and developed. Produktionen af ​​solfangere ved hjælp af denne anden-generations teknologi kaldes "Thin Film Technology." Tredje generations solceller energiteknologier bliver i øjeblikket forsket og udviklet. The objective is to improve the power of solar cells even further (while keeping production costs to a minimum) in which case thirty to sixty percent of the sunlight hitting the panels will be converted into electricity. Målet er at forbedre effekten af ​​solceller endnu mere (og samtidig holde produktionsomkostningerne på et minimum), i hvilket tilfælde fra 30 til 60 procent af sollyset rammer paneler vil blive konverteret til elektricitet. (Currently, solar panels convert only about twenty percent.) But regardless of third generation solar technology, the second-generation solar cell is efficient enough to make solar technology viable – and a host of new solar-powered products have hit the consumer market. (I øjeblikket solpaneler konvertere kun omkring 20 procent.) Men uanset af tredje generation sol-teknologi, anden generation af solcelle er effektiv nok til at gøre sol-teknologi levedygtig - og et væld af nye sol-drevne produkter har ramt forbrugermarkedet.

Solar-powered calculators have been in use for a while now, we've all seen them. Solar-drevne lommeregnere har været i brug et stykke tid nu, har vi alle set dem. We have even seen a few other novelty devices. Vi har endda set et par andre nyhed enheder. But only in the last few years have solar devices come into serious and practical use. Men kun i de sidste par år har solenergi enheder kommet i alvorlig og praktisk brug. The last two years in particular have seen a virtual explosion of solar devices hitting the market. De sidste to år især har set en virtuel eksplosion af sol enheder rammer markedet. Solar flashlights (I've often wandered what use they were), solar-powered radios, and, recently, solar battery chargers. Solar lommelygter (jeg har ofte vandrede hvad nytter det var), sol-drevne radioer, og for nylig, sol batteriladere.

One can also now find a wide range of portable solar chargers and panels , which are lightweight and easy to transport, yet capable of providing a decent amount of power in even the most remote locations. Man kan nu også finde en bred vifte af bærbare sol opladere og paneler , der er let og nem at transportere, men alligevel i stand til at levere en anstændig mængde strøm i selv de mest afsidesliggende steder. Solar chargers are becoming a standard part of wilderness survival kits and emergency preparedness kits. Solar opladere er ved at blive en standard del af vildmark overlevelse kits og beredskab kits. All of this is a result of the developments in solar cell technology, and the coming of the Solar Age. Alt dette er et resultat af udviklingen i solcelle-teknologi, og den kommende i Solar Alder.
