Abstract

The photoelectric and optical characteristics of an organic solar cell (OSС) with a hole-transport layer based on a polyaniline complex and a photoactive layer with a bulk heterojunction based on P3HT polythiophene derivative and PC₇₁BM fullerene have been studied. The results of modeling the optical properties of the functional layers and experimental measurements of the OSC characteristics enabled the optimal values of the thickness of the functional layers resulting in the maximum power conversion efficiency of the device to be identified. It has been determined that the hole-transport layer with a thickness of 30–60 nm, while having a transmission of more than 80%, effectively transferred holes to the photoanode from the photoactive layer, in which the exciton generation rate was 5.6–5.9 × 10¹⁶ cm^–2 s^–1. These values of the exciton generation rate at the maximum total light absorption in the device were provided by a photoactive layer with a thickness of 90–100 nm.

摘要

研究了具有基于聚苯胺络合物的空穴传输层和基于 P3HT 聚噻吩衍生物和 PC ₇₁ BM 富勒烯的本体异质结光敏层的有机太阳能电池 (OSС) 的光电和光学特性。功能层的光学特性建模和 OSC 特性的实验测量结果能够确定功能层厚度的最佳值，从而确定设备的最大功率转换效率。已经确定，厚度为 30-60 nm 的空穴传输层，同时具有超过 80% 的透射率，有效地将空穴从光敏层传输到光电阳极，其中激子产生率为 5.6-5.9 × 10¹⁶厘米^–2秒^–1 . 这些器件中最大总光吸收时的激子生成速率值由厚度为 90-100 nm 的光敏层提供。
