Abstract

Photon management strategies are crucial to improve the efficiency of perovskite thin film (PTF) solar cell. In this work, a nano-cone (NC) based 2D photonic nanostructure is designed and simulated aiming at achieve superior light trapping performance by introducing strong light scattering and interferences within perovskite active layer. Compared to the planar PTF solar cell, the NC nanostructured device with 45 degrees half apex angle obtains highest short-circuit current density, which improved over 20% from 15.00 mA/cm to 18.09 mA/cm. This work offers an alternative design towards effective light trapping performance using 2D photonic nanostructure for PTF solar cell and could potentially be adopted as the nano-structuring strategy for the future perovskite solar cell industry.

摘要

光子管理策略对于提高钙钛矿薄膜（PTF）太阳能电池的效率至关重要。在这项工作中，设计并模拟了一种基于纳米锥（NC）的二维光子纳米结构，旨在通过在钙钛矿活性层内引入强光散射和干涉来实现卓越的光捕获性能。与平面PTF太阳能电池相比，半顶角为45度的NC纳米结构器件获得了最高的短路电流密度，从15.00 mA/cm提高到18.09 mA/cm，提高了20%以上。这项工作为使用二维光子纳米结构实现PTF太阳能电池的有效光捕获性能提供了一种替代设计，并有可能被用作未来钙钛矿太阳能电池行业的纳米结构化策略。
