摘要

本文构筑了一种低层数SnO

反蛋白石光子晶体结构薄膜。基于反蛋白石光子晶体结构材料特有的有序多孔结构及慢光子效应，可有效提升光吸收，使其在太阳能电池、光催化等领域发挥出巨大的作用。本文通过无皂乳液聚合法，控制单体和引发剂的使用量，制备了3种粒径大小的聚苯乙烯(Polystyrene，PS)微球；采用垂直沉积自组装法，同时在分散液中滴加少量十二烷基硫酸钠(Sodium Dodecyl Sulfate，SDS)，制备低层数PS微球蛋白石模板；最后通过牺牲模板法制备低层数SnO

反蛋白石光子晶体薄膜。该结构薄膜相比于平面结构，在具有较高的比表面积的同时，在可见光波长范围内，吸光度与漫反射率均有所提升。该反蛋白石光子晶体薄膜为设计钙钛矿太阳能电池的电子传输层提供了新策略。

Abstract

A low-layer SnO

photonic crystal thin film with an inverse opal structure was constructed in this study. Based on the unique ordered porous structure and slow photon effect of inverse opal photonic crystal materials

it effectively enhances light absorption and plays a significant role in fields such as solar cells and photocatalysis. In this study

three sizes of polystyrene (Polystyrene

PS) microspheres were prepared using a soap-free emulsion polymerization method

with controlled amounts of monomers and initiators. A small amount of sodium dodecyl sulfate (Sodium Dodecyl Sulfate

SDS) was added dropwise to the dispersion

solution during vertical deposition self-assembly to prepare low-layer PS opal templates. Finally

a low-layer SnO

inverse opal photonic crystal film was obtained using a sacrificial template method. Compared with planar structures

this film exhibits enhanced light absorption and diffuse reflectance while maintaining a higher specific surface area within the visible wavelength range. The inverse opal photonic crystal film provides a new strategy for designing electron transport layers in perovskite solar cells.
