It might sound curiously strange but according to the scientists it is a possibility. Det lyder måske mærkeligt mærkeligt, men ifølge forskerne er det en mulighed. The possibility is that we could see, very soon, a rare type of super-thin solar cells which would be printed on plastic sheets which can be rolled or on the window glasses. Muligheden er, at vi kunne se, meget snart, en sjælden form for super-tynde solceller , som vil blive trykt på plastic plader, der kan rulles eller på vinduet glas.

Of course, the glasses need to be transparent, partially, according to them. Selvfølgelig skal de briller for at være gennemsigtige, delvist, ifølge dem. These super-thin solar cells are said to be more effective and user-friendly than the existing and cost-effective photovoltaic cells. Disse super-tynde solceller siges at være mere effektiv og brugervenlig end de eksisterende og omkostningseffektive solceller. Though the photovoltaic cells have always remained efficient, their main draw back is that they can't be incorporated into different panel designs with much ease. Selvom solceller altid har været effektiv, deres vigtigste trække tilbage, er, at de ikke kan integreres i forskellige panel design med stor lethed.

A team of researchers at the University of Illinois, headed by John A. Rogers, has devised this unique solar cell. Et hold af forskere ved University of Illinois, ledet af John A. Rogers, har udtænkt denne enestående solcelle. The team says that this cell could be combined in flexible arrays. Holdet siger, at denne celle kan kombineres i fleksible arrays. Amazingly, these arrays could be partially transparent, though sometimes. Utroligt, kan disse arrays er delvist gennemsigtig, men nogle gange. As a matter of interest, experts have given this rare innovative process a bizarre name too – “the rubber-stamp approach.” Som et spørgsmål af interesse, har eksperter givet denne sjældne innovative proces et bizart navn også - "gummi-stempel tilgang."

However, the basic formula of making these cells are somewhat similar to that of photovoltaic cells. Det grundlæggende formel til fremstilling af disse celler er noget, der svarer til solceller. Like most of the photovoltaic cells, the super-thin solar cells too have pn junctions- a compulsory feature in almost every photovoltaic cell. Som de fleste af solceller, også de super-tynde solceller har pn vejkryds-et obligatorisk element i næsten alle solcelle.

While making, the scientists use a block of single-crystal silicon. Mens gøre, forskerne bruge en blok af enkelt-krystal silicium. On this piece of silicon, a semiconductor, they make a pattern of micro bars. På dette stykke af silicium, en halvleder, gør de et mønster af mikro stænger. Notably, these micro bars, arranged according to a patterned gap, have a thickness of a few micrometers only. Især disse mikro stænger, arrangeret ifølge et mønstret hul, har en tykkelse på nogle få mikrometer alene. Technically, the method, the scientists use, of making these cells is much more complex and demanding. Teknisk, den metode, forskerne bruger, for at gøre disse celler er meget mere kompleks og krævende. It is a type of etching process. Det er en type af ætsningsprocessen. The blocks, after being made using silicon, are transferred to get printed on the substrates of other materials. Blokkene, efter at være fremstillet ved hjælp af silicium, overføres for at blive trykt på substrater af andre materialer. This technique is a time taking event and can be finished in many steps. Denne teknik er en tid tager begivenhed og kan være færdigt i mange trin. When the bars are printed on the substrates, it requires a metal grid, as an electrical connector, to cover the structure which leads to electrical connections. Når stængerne er trykt på substraterne, kræver et metalgitter, en elektrisk konnektor, for at dække den struktur, som fører til elektriske forbindelser.

There is no doubt that these innovative and optimized ultra-thin solar cells are going to cause a revolution in the field of solar cells. Der er ingen tvivl om, at disse innovative og optimeret ultra-tynde solceller kommer til at skabe en revolution inden for solceller. Moreover, it is going to be too cost-effective. Desuden er det vil være for omkostningseffektiv. The key to the success of this technology lies in the wide-scale production of these cells. Nøglen til succes for denne teknologi ligger i den brede-skala produktion af disse celler.
