Abstract

Here, we report photonic nanostructures replicated from the adaxial epidermis of flower petals onto light-polymerized coatings using low-cost nanoimprint lithography at ambient temperature. These multifunctional nanocoatings are applied to confer enhanced light trapping, water repellence, and UV light and environmental moisture protection features in perovskite solar cells. The former feature helps attain a maximum power conversion efficiency of 24.61% (21.01% for the reference cell) without any additional device optimization. Added to these merits, the nanocoatings also enable stable operation under AM 1.5G and UV light continuous illumination or in real-world conditions. Our engineering approach provides a simple way to produce multifunctional nanocoatings optimized by nature's wisdom.

摘要

在此，我们报告了利用低成本的纳米压印光刻技术在室温下将花瓣近轴表皮复制到光聚合涂层上形成的光子纳米结构。这些多功能纳米涂层应用于钙钛矿太阳能电池，可增强光捕获、防水以及紫外线和环境湿度防护功能。前一个功能有助于在无需任何额外器件优化的情况下实现24.61%的最大功率转换效率（参考电池为21.01%）。除了这些优点外，纳米涂层还能在AM 1.5G和紫外线连续照射下或实际条件下实现稳定运行。我们的工程方法提供了一种简单的方式来生产受自然智慧优化的多功能纳米涂层。
