【Abstract】 Thin film Cu2S-CdS solar cells offer a very promising photovoltaic device for large scale terrestrial application.In this paper,the experimental reulst of our laboratory are presented.The cell lifetime accelerative tests was perfomed under five conditions and the results was compared between both encapsulated and conventional cells.(1) UV radiation test.(2) Xenon lamp simulation of sunlight radiation.(S)Acceleration test of humidity and rainfall.(4)Simulation enviromental temperature cycle test.(S)Accelarate test under constant stress.In accordance with the diversity of degradation of the cells,we carried on extrapolation experimental results demonstrated that the lifetime of the well encapsulated Cu2S-CdS solar cells can be extrapolated to 10-15 years.更多还原
