Abstract

This paper introduces the fundamental physical characteristics of organic photovoltaic (OPV) devices. Photoelectric conversion efficiency is crucial to the evaluation of quality in OPV devices, and enhancing efficiency has been spurring on researchers to seek alternatives to this problem. In this paper, we focus on organic photovoltaic (OPV) devices and review several approaches to enhance the energy conversion efficiency of small molecular heterojunction OPV devices based on an optimal metal-phthalocyanine/fullerene (C(60)) planar heterojunction thin film structure. For the sake of discussion, these mechanisms have been divided into electrical and optical sections: (1) Electrical: Modification on electrodes or active regions to benefit carrier injection, charge transport and exciton dissociation; (2) Optical: Optional architectures or infilling to promote photon confinement and enhance absorption.

摘要

本文介绍了有机光伏（OPV）器件的基本物理特性。光电转换效率对于评估OPV器件的质量至关重要，提高效率一直激励着研究人员寻找解决该问题的替代方案。在本文中，我们聚焦于有机光伏（OPV）器件，并基于优化的金属酞菁/富勒烯（C(60)）平面异质结薄膜结构，综述了几种提高小分子异质结OPV器件能量转换效率的方法。为便于讨论，这些机制分为电学和光学两部分：（1）电学：对电极或有源区进行改性，以利于载流子注入、电荷传输和激子解离；（2）光学：采用可选的结构或填充材料，以促进光子限制并增强吸收。
