Bertoluzzi, L.等人首次直接测量全钙钛矿太阳能器件中的离子迁移率和浓度。对无回滞ITO/PTAA/FACsPb(IBr)3/C60结构的钙钛矿太阳能电池进行瞬态测量,并确定该器件的离子浓度约为1 x 10 18 /cm3和离子迁移率约为3×10-7 cm2/Vs。测得的离子迁移率比先前使用钙钛矿太阳能电池和钙钛矿薄膜确定的最高估计值高出2个数量级。
Bertoluzzi, L. et al. In-situ measurement of electric-field screening in hysteresis-free PTAA/FACsPb(IBr)3/C60 perovskite solar cells gives an ion mobility of ~3x10-7cm2/Vs; two orders of magnitude faster than reported for metal-oxide-contacted perovskite cells with hysteresis. J. Am. Chem. Soc.
