A number of companies are currently involved in thin-fllm photovoltaics [17], and low-cost multilayer thin-fllm amorphous silicon and CdTe (cadmium telluride) systems have already been installed in large numbers with efficiencies of the order of 10% and of about 80% output after 25 years of operation. Large-scale plants have been announced for the so-called CIS (cadmium indium selenide) and CGIS (copper gallium indium diselenide), technologies with production efficiencies in the range 12-13% and laboratory measurements up to 19.9% [18]. 

There are three main thin-film PV cells under development at present amorphous Si, CdTe/CdS, and Cl(G)S/CdS [C1(G)S refers to copper indium (gallium) selenide]. Of these, the last two are polycrystalline (as opposed to amorphous), and both normally employ CD CdS. Crystalline Si cells are not thin films, being at least tens and usually hundreds of microns in thickness, compared to the few microns of active thickness of the thin-fihn cells.

Another area of development is in lower-cost thin- and ultrathin-film designs. One such product is made by Nanosolar of copper indium gallium selenide (CIGS), which is claimed to achieve up to 19.5% efficiency and is as thin as a newspaper. This claim is yet to be proved. The collector cost is also reduced, because the substrate material on which the ink is printed is much less expensive than the stainless steel substrates that are often used in thin-film solar panels. The manufacturer claims a five- to tenfold reduction in the collector cost (about 1/W) compared to conventional PV cells.

Other materials that can be used for semiconductor solar batteries are gallium arsenide GaS, cadmium telluride TeCd, and copper-indium selenide CuInSe.

Most of the flexible recharging devices existing on the market are equipped with CIGS (copper indium gallium selenide) PV cells based on amorphous sUicon (FlexceU, PowerFilm Solar ).
