杂化钙钛矿电池电极层载流子的传输特性

Transport characteristics of current carriers in electrode layer of hybrid perovskite solar cells

提出了层状结构薄膜太阳能电池器件各层面内和面间载流子传输模型.依据不同电路结构获得薄膜层的面内和面间电阻数据,推演出器件的各层电阻值.实验结果表明:TiO_(2)层的面间电阻为24~40Ω,钙钛矿(PVK)层的面间电阻为2~6Ω;对于薄膜层数较少,例如Glass-PVK-TiO_(2)和Glass-PVK-TiO_(2)掩膜-PVK掩膜的情况,由于接触电阻的弱效应,模型模拟的电阻与实际测量之间的偏差小于11%.

The bulk and interface carrier transport models for each layer of thin-film solar cell devices with layered structures were proposed.The bulk and interface resistance data of the film layer were obtained according to the different circuit structures caused by the coating of different layers,and the resistance values of each layer of the device were deduced.The analyzed interface resistance of the TiO_(2)layer was between 24Ωand 40Ω,and that of the PVK layer was between 2Ωand 6Ω.For the case of few thin film layers,such as Glass-PVK-TiO_(2)and Glass-PVK-TiO_(2)mask-PVK mask,the error between simulated resistance and actual measurement was less than 11%due to the weak effect of contact resistance.
