摘要
Abstract
With TiO2/perovskite/P3 HT n-i-p perovskite type battery as research object, effects of thermal annealing temperature of TiO2 film on the crystallinity of TiO2 film,morpholo-gy of perovskite film deposited on the treated TiO2 layer,and the photovoltaic performance of perovskite solar cells were investigated.Performance of perovskite solar cell device was also stud-ied by comparing P3 HT doping and different batches of P3 HT materials.The results clearly show that annealing processing of TiO2 layer and property of P3 HT play important roles in tuning per-ovskite solar cell performance.An optimized annealing condition of 300 ℃ for 45 min for theTiO2 film was obtained.The power conversion efficiency(PCE)was further improved to 11.27%by increasing the thermal annealing temperature of TiO2 layer to 500 ℃.A PCE of 6.77% was a-chieved for the cell with a 190 nm-thick perovskite film layer.By optimizing P3 HT layer with chemical doping and batch screening,an improved device performance of 8.18% with VOC =0.98 V,JSC =19.94 mA/cm2 ,fF =0.42,η(PCE)=8.18% was achieved.The system atic optimiza-tion of TiO2 electronic transport layer and P3 HT hole transport layer is of great significance to the preparation of high performance structure of n-i-p type perovskite battery.关键词
