利用电容电压（C-V）测量和电荷调制光谱（CMS）技术研究了锡钙钛矿太阳能电池的I-V滞后特性。太阳电池器件（ITO/PEDOT:PSS/CH3NH3SnI3(MASnI3)/C60/Al）的C-V特性和CMS表明，电子在正偏置电压下从C60层注入到MASnI3层，而在负偏置电压下注入的电子返回到C60层。结果表明，锡钙钛矿太阳能电池的I-V滞后是由于载流子注入到masni3层引起的。本研究提供了一种评价锡钙钛矿太阳能电池载流子运动的方法。
We investigated the I-V hysteresis of tin perovskite solar cells using capacitance-voltage (C-V) measurement coupled with charge modulation spectroscopy (CMS). The C-V characteristics and CMS of the solar cell device (ITO/PEDOT:PSS/CH3NH3SnI3(MASnI3)/C60/Al) showed that electrons inject from a C60layer into an MASnI3layer at positive bias voltage, while the injected electrons return to a C60layer at negative bias voltage. Results suggested that I-V hysteresis of tin perovskite solar cells is originated from the carrier injection into an MASnI3layer. This study provides a method for evaluating the carrier motion in tin perovskite solar cells.
