High-efficiency multijunction devices use multiple bandgaps, or junctions, that are tuned to absorb a specific region of the solar spectrum to create solar cells having record efficiencies over 45%. The maximum theoretical efficiency that a single-bandgap solar cell can achieve with non-concentrated sunlight is about 33.5%, primarily because of ...

Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed. In the case of uranium, the ferric sulfate ...

A luminescent solar concentrator (LSC) is a transparent piece of plastic or glass that has a fluorescent dye or quantum dots embedded or painted on it. The dye absorbs light and then fluoresces creating a glow that propagates by total internal reflection to the edge of the sheet where the light is absorbed by a narrow solar cell.

Solar water heating systems use heat exchangers to transfer solar energy absorbed in solar collectors to potable (drinkable) water. Heat exchangers can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion.
