Photovoltaic technology using perovskite solar cells has emerged as a potential solution in the photovoltaic makings for cost-effective manufacturing solutions deposition/coating solar cells. The hybrid perovskite-based materials possess a unique blend from low bulk snare concentrations, ambipolar, broad optical absorption properties, extended charge carrier diffusion, and charge transport/collection properties, making them favourable for solar cell applications. However, perovskite solar cells devices suffer from the effects of natural instability, leading to their rapid degradation while bared to water, oxygen, as well as ultraviolet rays, are irradiated and in case of high temperatures. It is essential to shield the perovskite film from damage, extend lifetime, and make it suitable for device fabrications. This paper focuses on various device strategies and computational attempts to address perovskite-based solar cells' environmental stability issues.
使用钙钛矿太阳能电池的光伏技术已成为光伏制造领域中一种具有潜力的解决方案，可实现具有成本效益的太阳能电池制造解决方案的沉积/涂层。基于混合钙钛矿的材料具有独特的特性组合，包括低体陷阱浓度、双极性、宽光学吸收特性、扩展的电荷载流子扩散以及电荷传输/收集特性，这使得它们非常适合用于太阳能电池应用。然而，钙钛矿太阳能电池器件会受到自然不稳定性的影响，导致在暴露于水、氧气、紫外线照射以及高温环境时迅速降解。保护钙钛矿薄膜免受损害、延长其寿命并使其适合器件制造至关重要。本文重点关注各种器件策略和计算方法，以解决基于钙钛矿的太阳能电池的环境稳定性问题。
