Inverted Perovskite Solar Cells (PSCs) with Poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT:PSS) as hole transport layer on account of its low-temperature solution processability, good flexibility and good film forming ability. Bis(acetylacetonato)dioxomolybdenum(VI) [CH₃COCH = (O-)CH₃]₂MoO₂ (BADM) as an effective dopant has been introduced into PEDOT:PSS for planar PSCs. The results show that the power conversion efficiency (PCE) is increased from 14.26% to 17.11% by using BADM to modify PEDOT:PSS, which is mainly due to the increase of filling factor and short circuit current density. Not only that, BADM doping can also improve the extensibility of perovskite film, which can be reflected on flexible substrate, when slightly bending, there are almost no cracks.

由于其低温溶液加工性、良好的柔韧性和良好的成膜能力，具有聚（3,4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）作为空穴传输层的倒置钙钛矿太阳能电池（PSC）。双(乙酰丙酮)二氧代钼(VI) [CH ₃ COCH = (O-)CH ₃ ] ₂ MoO ₂(BADM) 作为一种有效的掺杂剂已被引入到用于平面 PSC 的 PEDOT:PSS 中。结果表明，利用BADM修饰PEDOT:PSS，功率转换效率(PCE)从14.26%提高到17.11%，这主要是由于填充因子和短路电流密度的增加。不仅如此，BADM掺杂还可以提高钙钛矿薄膜的延展性，这可以体现在柔性基板上，稍微弯曲时，几乎没有裂纹。
