实现高效薄膜硅太阳能电池的最大挑战之一是设计高效的光捕获系统，因为固有的薄吸收层所施加的短光程长度。在本文中，提出了一种有效的光捕获系统的随机纹理表面和一维光子晶体（随机纹理光子晶体; RTPC）的组合。利用实验和时域有限差分模拟的结果，讨论了织构对RTPC光学性能的影响。该RTPC背反射器（BR）可以提供高反射率和强光散射，从而导致氢化非晶硅（a-Si：H）太阳能电池的光电流密度增加。结果表明，高织构RTPC BR的a-Si：H太阳能电池效率为9.6%，远高于平坦AZO/Ag BR的7.6%和织构AZO/Ag BR的9.0%。这种RTPC BR为制造高效率、低成本的薄膜硅太阳能电池提供了一种新方法。
One of the foremost challenges in achieving high-efficiency thin-film silicon solar cells is in devising an efficient light trapping system because of the short optical path length imposed by the inherent thin absorption layers. In this paper, an efficient light trapping system is proposed using a combination of randomly textured surfaces and a one-dimensional photonic crystal (randomly textured photonic crystal; RTPC). The influence of the texture on the optical performance of RTPCs is discussed using the results of an experiment and a finite-difference time-domain simulation. This RTPC back reflector (BR) can provide high reflectivity and strong light scattering, resulting in an increased photocurrent density of the hydrogenated amorphous silicon (a-Si:H) solar cell. As a result, the highly textured RTPC BR yielded an efficiency of 9.6% for a-Si:H solar cell, which is much higher than the efficiency of 7.6% on flat AZO/Ag BR and 9.0% on textured AZO/Ag BR. This RTPC BR provides a new approach for creating high-efficiency, low-cost thin-film silicon solar cells.
