The production of electricity is important, suitable and secure for human living, yet electricity is actually generated mainly from fossil fuels and nuclear energy, calling for renewable energies such as solar, wind and tidal renewable energies such as solar, wind and tidal. Solar energy is broadly harvested by various types of solar cells. Three-dimensional perovskite solar cell exhibits high power conversion efficiency of 25.2% with low stability, whereas two-dimensional perovskite solar cell exhibits better stability with moderate power conversion efficiency. Hence, we review two-dimensional perovskite solar cells fabricated with varying numbers of hybrid two-dimensional perovskite layers, organic cations, deposition techniques, the addition of additives and capping layers to improve power conversion efficiency with long-term better stability.

电力生产对于人类生活来说是重要的、合适的和安全的，但实际上电力主要来自化石燃料和核能，需要太阳能、风能等可再生能源和太阳能、风能和潮汐能等潮汐可再生能源。太阳能广泛地由各种类型的太阳能电池收集。三维钙钛矿太阳能电池表现出25.2%的高功率转换效率和低稳定性，而二维钙钛矿太阳能电池表现出更好的稳定性和中等功率转换效率。因此，我们回顾了用不同数量的混合二维钙钛矿层、有机阳离子、沉积技术、添加添加剂和覆盖层制造的二维钙钛矿太阳能电池，以提高功率转换效率和长期更好的稳定性。
