本文在PbCl2与PbI2摩尔比为1:1的DMF溶液中加入PbCl2粉末,在室温下成功制备了新型PbICl前驱体溶液,并首次用气相辅助溶液法制备了高效的平面钙钛矿太阳电池。结果表明,PbCl2在DMF中的溶解度显著提高,生成的PbICl薄膜结晶度低,多孔性好,在150℃的空气中经CH3NH3NH3I蒸气处理后,可以很容易地转变为无卤化铅残留的CH3NH3PbI3−xClx薄膜。基于0.8M PbICl前驱体溶液的平面钙钛矿太阳能电池具有最高的光伏转换效率11.11%,开路电压0.93nV,短路光电流密度17.31mA/cm−2,填充因子0.69。
In this paper, a new precursor solution of PbICl is successfully prepared by adding PbCl2powder into the DMF solution of PbI2at room temperature with the molar ratio of PbCl2and PbI2at 1:1 and demonstrated for efficient planar perovskite solar cell by vapor-assisted solution process for the first time. The results reveal that the solubility of PbCl2in DMF is dramatically improved by the formation of PbICl and the resulting PbICl thin film with low crystallinity and porous morphology can be easily converted to CH3NH3PbI3−xClxthin film without any lead halide residuals by the treatment of CH3NH3I vapor at 150 °C in air. The planar perovskite solar cells based on the 0.8 M PbICl precursor solution exhibit the highest photovoltaic conversion efficiency of 11.11% along with an open-circuit voltage of 0.93 V, a short-circuit photocurrent density of 17.31 mA cm−2and a fill factor of 0.69.
