Abstract Photon management is an efficient route to ameliorate optical issues for improving the efficiency of solar cells. On account of reflection loss and spectral mismatch for silicon solar cells, we herein firstly demonstrate a photon management of combining antireflection and luminescence down-shifting coatings to simultaneously suppress the reflection of incident light with nanoporous structure and improve the spectra response of silicon solar cells in short wavelength with in-situ fabricated perovskite quantum dots composite film. Antireflection film can be obtained by sacrificing CdxZn1-xSeyS1-y/ZnS quantum dots template in PDMS composite film, which can bring 9.7% improvement in photocurrent for amorphous silicon solar cells. By further combining perovskite quantum dots down-shifting luminescence coating, an absolute improvement of 1.05% in power conversion efficiency was achieved. The photon management combining the antireflection and luminescence down-shifting coatings could provide a low-cost, simple but effective way to address the optical issues and improve the device performance of optoelectronic devices.

摘要 光子管理是改善太阳能电池效率的光学问题的有效途径。由于硅太阳能电池的反射损失和光谱不匹配，我们在此首次展示了一种结合抗反射和发光下移涂层的光子管理，以同时抑制具有纳米多孔结构的入射光的反射并改善硅太阳能电池的光谱响应。原位制备的钙钛矿量子点复合薄膜的短波长。通过牺牲PDMS复合膜中的CdxZn1-xSeyS1-y/ZnS量子点模板可以获得减反射膜，可为非晶硅太阳能电池带来9.7%的光电流提升。通过进一步结合钙钛矿量子点下移发光涂层，绝对提升1。实现了 05% 的功率转换效率。结合抗反射和发光下移涂层的光子管理可以提供一种低成本、简单但有效的方法来解决光学问题并提高光电器件的器件性能。
