具有双钙钛矿结构的Cs_2AgBiBr_6有望应用于无铅、稳定的光电器件，近年来受到广泛关注。在这个阶段，使用双钙钛矿和混合钙钛矿的光电器件的结构是相同的。并且双钙钛矿和混合钙钛矿的能带结构不同，这将导致双钙钛矿器件中的能级失配，从而严重制约器件性能的进一步提高。首次报道了利用聚3-己基噻吩（P3 HT）/MoO 3/聚[双（4-苯基）（2，4，6-三甲基苯基）胺]（PTAA）构筑能级梯度来解决这一问题。能级梯度的构建主要是通过P3 HT和PTAA实现的。MoO 3起着保护衬底（P3 HT）的作用，并且不妨碍空穴传输，因为它本身是p型半导体。与标准器件相比，采用P3 HT/MoO 3/PTAA的器件的冠军功率转换效率提高了四分之一以上。此外，在冠军器件中，功率转换效率达到1.94%，短路电流为2.80 mA/cm 2。
Cs2AgBiBr6having a double perovskite structure is expected to be used in nonlead and stable optoelectronic devices and has received wide attention recently. At this stage, structures of optoelectronic devices using double perovskite and hybrid perovskite are the same. And the energy band structures of double perovskite and hybrid perovskite are different, which will cause energy-level mismatch in the device with double perovskite, which in turn will seriously restrict further improvement of the device performance. A strategy to solve this problem by constructing energy-level gradients with poly(3-hexylthiophene) (P3HT)/MoO3/poly[bis(4-phenyl)(2,4,6-trimethylphenyl)-amine] (PTAA) was reported for the first time. The construction of energy-level gradient is mainly achieved by P3HT and PTAA. MoO3plays a role in protecting the substrate (P3HT) and does not hinder hole transport because it is itself a p-type semiconductor. The champion power conversion efficiency of devices with P3HT/MoO3/PTAA is improved by more than a quarter compared to the standard devices. Moreover, in the champion device, the power conversion efficiency achieved 1.94% with a short-circuit current of 2.80 mA/cm2.
