Organic-inorganic halide perovskite solar cells have enormous potential to impact the existing photovoltaic industry. As realizing a higher conversion efficiency of the solar cell is still the most crucial task, a great number of schemes were proposed to minimize the carrier loss by optimizing the electrical properties of the perovskite solar cells. Here, we focus on another significant aspect that is to minimize the light loss by optimizing the light management to gain a high efficiency for perovskite solar cells. In our scheme, the slotted and inverted prism structured SiO2 layers are adopted to trap more light into the solar cells, and a better transparent conducting oxide layer is employed to reduce the parasitic absorption. For such an implementation, the efficiency and the serviceable angle of the perovskite solar cell can be promoted impressively. This proposal would shed new light on developing the high-performance perovskite solar cells.
有机-无机卤化物钙钛矿太阳能电池对现有光伏产业具有巨大的潜在影响。由于实现更高的太阳能电池转换效率仍然是最关键的任务，人们提出了大量方案，通过优化钙钛矿太阳能电池的电学性能来最小化载流子损失。在此，我们关注另一个重要方面，即通过优化光管理来最小化光损失，以提高钙钛矿太阳能电池的效率。在我们的方案中，采用开槽和倒置棱镜结构的二氧化硅层将更多的光捕获到太阳能电池中，并使用更好的透明导电氧化物层来减少寄生吸收。通过这样的实现方式，钙钛矿太阳能电池的效率和可用角度可以得到显著提高。该提议将为高性能钙钛矿太阳能电池的开发提供新的思路。
