高效率钙钛矿太阳电池的界面修饰及其研究进展（英文）
|
摘要
有机-无机杂化钙钛矿由于其优异的电学及光学性质,成为制备太阳电池吸光层的理想材料.无论反式还是正式结构的钙钛矿太阳电池,均包含以下几个关键界面:电极/电子传输层界面、电子传输层/钙钛矿界面、钙钛矿/空穴传输层界面、空穴传输层/电极界面.这些界面的性质对于电池性能至关重要,因为激子的形成、分离及复合都直接决定于这些界面.此外,器件的稳定性也受界面性质的影响.因此,界面电荷转移以及相应的界面修饰对于制备高效率、高稳定性电池器件具有重要助益.本论文将侧重综述近期在钙钛矿电池领域关于界面修饰问题的重大突破与进展.
Organic-inorganic hybrid halide perovskite materials have been a suitable active layer in solar cells due to the extraordinary photonic and electronic properties.Perovskite solar cells(PSCs),no matter conventional structure or inverted structure,contain several key interfaces,including electrode/electron transport materials(ETM) interface,ETM/perovskite interface,perovskite/hole transport materials(HTM) interface,HTM/electrode interface.The interface is vital to the overall performance of the devices,since the exciton formation,dissociation,and recombination are directly related to the interface.Moreover,the degradation of devices is also highly sensitive to the interface.As a result,the deep understanding of the interfadal charge transfer and corresponding interfadal engineering is extremely important to achieve high-performance and high-stability PSCs.This review mainly focuses on the recent progress of interfacial engineering in PSCs,including conventional structured PSCs,PSCs employing carbon counter electrode,and inverted structured PSCs.
