Perovskite solar cells (PSCs) are believed to be one of a promising choice of the third-generation technology platforms to address the increasing green energy demands. The main objective of this work is to fabricate a hole transport layer (HTL) based on doped polyaniline (PANI) and graphene oxide with different ratios. This layer was characterized using Raman spectroscopy, scanning electron microscope (SEM), atomic force microscopy (AFM), UV–Visible spectroscopy, photoluminescence, contact angle, Hall effect and current density–voltage measurements. Photoluminescence confirmed that the HTL of PANI/GO with 1:0.5 ratio had the highest efficiency to extract hole carriers. The conductivity and carrier concentrations of this layer were increased with the addition of small amounts of GO up to 1:0.5 and declined at the high ratio of 1:1. The optimal performance of the fabricated inverted PSC using HTL of PANI/GO with 1:0.5 ratio had short-current density (J_sc), open circuit voltage (V_oc), fill factor (FF) and efficiency of 21.23 mA/cm², 0.52 V, 0.67 and 9.24%, respectively.

钙钛矿太阳能电池（PSC）被认为是解决日益增长的绿色能源需求的第三代技术平台的一种有前途的选择。这项工作的主要目的是基于掺杂聚苯胺（PANI）和氧化石墨烯以不同比例制造空穴传输层（HTL）。使用拉曼光谱，扫描电子显微镜（SEM），原子力显微镜（AFM），紫外可见光谱，光致发光，接触角，霍尔效应和电流密度-电压测量来表征该层。光致发光证实，PANI / GO的HTL以1：0.5的比例提取空穴载体的效率最高。通过添加少量的GO至1：0.5可以增加该层的电导率和载流子浓度，并以1：1的高比率降低。Ĵ _SC），开路电压（V _OC），填充因子（FF）和21.23毫安/厘米的效率²，分别0.52 V，0.67和9.24％。
