在1987年至1994年期间，许多实验室为具有多晶CdTe和CuIn1−xGaxSe2（CIGS）吸收剂的薄膜电池的真正显着的效率增益做出了贡献。总面积效率已经从10%以上增加到16%以上，这些电池现在可以与具有可比带隙的单晶电池进行比较。许多因素促成了这些增益，但最重要的是耗尽区中复合态的减少和由此导致的正向电流密度的下降。
During the period between 1987 to 1994, a number of laboratories have contributed to truly remarkable efficiency gains for thin-film cells with polycrystalline CdTe and CuIn1−xGaxSe2(CIGS) absorbers. Total-area efficiencies have increased from just above 10% to over 16%, and these cells can now be sensibly compared with single-crystal cells of comparable bandgap. A number of factors have contributed to these gains, but the most significant has been the reduction of recombination states in the depletion region and the resulting drop in forward-current density.
