Abstract
During the period between 1987 to 1994, a number of laboratories have contributed to truly remarkable efficiency gains for thin-film cells w ith polycrystalline CdTe and CuIn1-XGaXSe2 (CIGS) absorbers. Total-are a efficiencies have increased from just above 10% to over 16%, and the se cells can now be sensibly compared with single-crystal cells of com parable bandgap. A number of factors have contributed to these gains, but the most significant has been the reduction of recombination state s in the depletion region and the resulting drop in forward-current de nsity.
