Hybrid Perovskite Creates Opportunities for Efficient Solar Energy Harvesting at High Latitudes

High latitudes, characterized by extremely low temperatures, unique day-night cycles, and year-round ice and snow cover, present substantial challenges for energy supply and sustainability. Perovskite solar cells (PSCs) have emerged as a viable option due to their exceptional optoelectronic properties and low fabrication costs. Moreover, PSCs demonstrate unique application advantages in the face of distinctive climatic conditions of high latitudes, owing to their improved power generation performance under low temperatures and low irradiance, as well as superior bifacial light-harvesting potential. Herein, we examine the environmental conditions of high latitudes, including low temperatures, low irradiance, and high albedo, and evaluate the performance and suitability of perovskite films and solar cells under these conditions. We systematically review the structural and optoelectronic properties of perovskite absorption layer, as well as recombination mechanisms and performance of PSCs. Additionally, the potential of perovskite-based bifacial solar cells for large-scale power generation at high latitudes is explored. This review provides critical insights and guidance for the future development of PSCs at high latitudes.
