Recent Progress in Carbon Electrodes for Efficient and Cost-Benign Perovskite Optoelectronics

Abstract

With popularity of the perovskite optoelectronics, its material properties and device performances have been widely studied. However, the issues in cost management and continuous fabrication still hinder the commercialization of the perovskite optoelectronics. Especially, the conventional electrodes such as metal and transparent conducting oxide (TCO) have limitations due to the difficulties in fabrication which requires high temperature and vacuum processes, largely increasing the time and cost. Therefore, carbon materials with high electric conductivity and favorable work function are recently being noticed as alternatives to the conventional electrodes since the carbon materials are abundant in nature and low in the fabrication cost. Therefore, carbon electrode for the perovskite optoelectronics is widely studied to replace the conventional electrode, and utilizing carbon as an electrode can be the alternative solution for a future electrode model. In this review, the recent progress of carbon electrodes in perovskite optoelectronics and various applications will be discussed. [GRAPHICS] .
