Carbon-Based Perovskite Solar Cells: The Future Photovoltaic Technology

In recent years, perovskite solar cells (PSC) have attracted the attention of numerous research groups due to the dramatic increase in their energy conversion efficiency from 3.8% to 25.5% in just 12 years. This rapid evolution among all solar cells makes PSC a promising alternative for future electricity production, but not without first overcoming some barriers, including instability against humidity and costly manufacturing processes. For this work, a review of the literature related to the topic of PSC was carried out, with special emphasis on carbon-based perovskite solar cells, which stand out for their simple manufacturing process, low cost of components, and good stability, as carbon materials are inert to ion migration (which occurs from perovskite and metal electrodes) and are inherently resistant to water. Besides, they have developed fabrication technologies to scale-up, which makes them ideal candidates for industrialization, but first, these technologies must be optimized.
