This work studies annealing effects of the CH3NH3PbI3 perovskite film for solar cell applications by time-resolved photoluminescence (TR-PL) spectra. The different thermal annealing temperatures process influences the quality and exciton lifetime of the CH3NH3PbI3 perovskite film and importantly the device performance. The CH3NH3PbI3 perovskite film of the optimal thermal annealing temperatures (100°C) would significantly extended exciton lifetime and yield a higher open-circuit voltage, with short-circuit current density (JSC)=21.58mA/cm2, open-circuit voltage (VOC)=0.84V, fill factor (FF)=61.4%, and η=11.12%, respectively. 出版者： Elsevier Ltd 出版日期： 2015-12-01 出處： Solar Energy, 2015-12, Vol.122, p.1047-1051 版權： 2015 Elsevier Ltd 識別號： ISSN: 0038-092X 識別號： EISSN: 1471-1257 識別號： DOI: 10.1016/j.solener.2015.10.019
