摘要：

Photocurrent extraction and electron injection in CH3NH3PbBr3 (MAPbBr(3)) perovskite-based optoelectronic devices are both significantly increased by improving the contact at the PCBM/MAPbBr(3) interface with an extended solvent annealing (ESA) process. Photoluminescence quenching and x-ray diffraction experiments show that the ESA not only improves the contact at the PCBM/MAPbBr(3) interface but also increases the crystallinity of the MAPbBr(3) thin films The optimized dual-functional PCBM-MAPbBr(3) heterojunction based optoelectronic device has a high power conversion efficiency of 4.08% and a bright visible luminescence of 1509 cd m(-2). In addition, the modulation speed of the MAPbBr(3) based light-emitting diodes is larger than 14 MHz, which indicates that the defect density in the MAPbBr(3) thin film can be effectively reduced by using the ESA process.
