【摘要】 在10cm²的单晶硅片上,用喷涂热分解法制备了SnO₂/Si异质结太阳电池,在光强为100mW/cm²（AM1.5）的ELH灯照射下,全面积电池的光电转换效率η=10.79％,其有效面积的效率已达到11.99％。氧化锡膜是喷涂一种四氯化锡的混合物到加热的硅衬底上沉积而成的。这种电池的效率在很大程度上取决于硅和氧化锡之间的二氧化硅绝缘层,其最佳厚度为10—20（?）。文中给出了这种电池的温度系数曲线。更多还原

【Abstract】 SnO2/Si heterojunction solar cell is fabricated by the spray pyrolysis technique on single-crystal silicon wafer of 10 cm2 area.Under ELH lamp of the illumination of,100 mW/cm2 (AM1.5) which is used as simulating sunlight,the efficiency of 10.79% in total area of solar cell is measured,have achieved active area efficiency up to 11.99% An SnO2 film was deposited by the spray pyrolysis of SnCl- mixture onto a heated silicon wafer.This cell efficiency depend on a SiO2 thin insulating layer at the SnO2/Si interface,the optimun thickness of the insulating layer is about 10 to 20 A.The current-voltage characteristics at different temperatures of this cell are first given in this paper.更多还原
