用于钙钛矿太阳能电池的高效光管理
Highly efficient light management for perovskite solar cells
摘要:
有机-无机卤化物钙钛矿太阳能电池具有巨大的潜力来影响现有的光伏产业。由于实现更高的太阳能电池的转换效率仍然是最关键的任务,因此提出了大量的方案,以通过优化钙钛矿太阳能电池的电性能来最小化载流子损耗。在这里,我们关注另一个重要方面,即通过优化光管理来最大限度地减少光损失,以获得钙钛矿太阳能电池的高效率。在我们的方案中,采用开槽和倒棱镜结构的SiO2层,以捕获更多的光进入太阳能电池,并采用更好的透明导电氧化物层,以减少寄生吸收。对于这样的实施方式,可以显著地提高钙钛矿太阳能电池的效率和可使用角度。这一提议将为开发高性能钙钛矿太阳能电池提供新的思路。
英文摘要:
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.
