Large-grained Polycrystalline Silicon on Glass for Thin-film Solar Cells

Thin-film crystalline silicon solar cells

A photoelectric conversion efficiency of over 10% has been achieved in thin-film polycrystalline silicon solar cells which consists of a 2 μm thick layer of polycrystalline silicon with a very small grain size (microcrystalline silicon) formed by low-temperature plasma CVD. This has shown that if the recombination velocity at grain boundaries can be made very small, then it is not necessarily i...

SULFUR DIFFUSION IN POLYCRYSTALLINE THIN-FILM CdTe SOLAR CELLS

X-ray diffraction and photoluminescence measurements have been used to characterize the diffusion of S into CdTe during post growth annealing of CdTe solar cells. For anneals at 410°C in the presence of CdCl2, evidence that both a CdTe1-xSx phase and nearly-pure CdTe are present near the back contact is observed. The ternary phase becomes more prominent and the S concentration increases with de...

POLYCRYSTALLINE THIN FILM SOLAR CELLS: Present Status and Future Potential

Polycrystalline thin film solar cells based on copper indium diselenide (CuInSe2) and its alloys and cadmium telluride (CdTe) appear to be the most promising candidates for largescale application of photovoltaic energy conversion because they have shown laboratoryefficiencies in excess of 15%. Heterejunction devices with n-type cadmium sulfide (CdS) films show very low minority carrier recombin...
