| Abstract: |
| Perovskite solar cells (PSC) have attracted much attention in recent years due to their high efficiency and low manufacturing cost. To use this type of cells as transparent photovoltaic coatings, it is necessary to make PSCs transparent. To achieve this important feature and at the same time to optimize their performance, transparent and semi-transparent electrodes have become the subject of many researches. In this article, the use of graphene as a promising material for transparent and semi-transparent electrodes in PSCs is investigated. Graphene, a two-dimensional carbon allotrope with exceptional electrical conductivity, mechanical strength, and high transparency, is a suitable alternative to traditional transparent conducting oxides (TCO) in PSCs. In this study, the recent advances in the use of graphene in PSC fabrication are reviewed and the characteristics of electron extraction and collection and optimal current generation from it, which increases the overall efficiency of the cell, are discussed. In addition, the use of graphene in the anode and cathode electrodes allows more of the incident light to penetrate the perovskite active layer, which leads to improved photon absorption and subsequently higher power conversion efficiency. This article also addresses challenges and future prospects for the use of graphene-based conductive electrodes, including device stability, scalability, and cost-effectiveness. |
