我们报告的高效硫化铅太阳能电池的制造，显示功率转换效率接近4%，填充因子为60%，AM1.5照明下。两种不同的纳米晶体（NC）的尺寸对设备的性能和关键参数的影响进行了讨论，连同设备功能的特殊功能。结果表明，器件不受空间电荷的限制，器件性能受电荷陷阱的影响，而电荷陷阱的大小与纳米线的尺寸有关。
We report on the fabrication of efficient PbS solar cells, showing power conversion efficiencies approaching 4% and fill factors of 60% under AM1.5 illumination. The effect of the size of two different nanocrystals (NCs) on the performance and key parameters of the devices are discussed together with peculiar features of device functioning. The results prove that the devices are not under space-charge limitation and the device performance is influenced by charge trapping which is dependent on the size of the NCs.
