Organic solar cell — An organic photovoltaic cell (OPVC) is a photovoltaic cell that uses organic electronics a branch of electronics that deals with conductive organic polymers or small organic molecules[1] for light absorption and charge transport. The plastic… … Wikipedia
Dye-sensitized solar cell — A selection of dye sensitized solar cells A dye sensitized solar cell (DSSC, DSC or DYSC[1]) is a low cost solar cell belonging to the group of thin film solar cells.[2] … Wikipedia
Copper indium gallium selenide solar cells — Copper indium gallium selenide (CuIn1 xGaxSe2 or CIGS) is a direct bandgap semiconductor useful for the manufacture of solar cells. Because the material strongly absorbs sunlight, a much thinner film is required than of other semiconductor… … Wikipedia
Heterojunction — A heterojunction is the interface that occurs between two layers or regions of dissimilar crystalline semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the… … Wikipedia
Maximum power point tracking — Current voltage characteristics of a solar cell at a particular light level, and in darkness. The area of the yellow rectangle gives the output power. Pmax denotes the maximum power point Maximum power point tracking (MPPT) is a technique that… … Wikipedia
Hydrogen production — Hydrogen is commonly produced by extraction from hydrocarbon fossil fuels via a chemical path. Hydrogen may also be extracted from water via biological production in an algae bioreactor, or using electricity (by electrolysis), chemicals (by… … Wikipedia
