Preparation of biomimetic micro-nano structure and its improvement on power generation of crystalline silicon solar cells

以提高晶体硅太阳能电池发电量为目的,通过仿真设计,阳极氧化辅助微纳米加工的方法制备了一种仿生类复眼多级微纳米结构,并将该结构通过纳米压印的方法制备到高分子聚合物薄膜上,结合目前市场晶体硅组件的封装技术,将该多级结构薄膜应用到晶体硅太阳能电池中。测试结果表明:该多级结构由尺寸约为30μm的六边形微透镜阵列及约为200 nm的点阵组成。使用该多级结构的聚合物薄膜的商业晶体硅太阳能电池的发电量可以提高4%以上,具有良好的应用前景。

The purpose of this study was to increase the power generation of silicon based solar cells. Based on the design of simulation,the compound-eye-like hierarchical micro-nano structures were abtained by anodizing assisted micro-nano processing. Then the hierarchical nanostructures were prepared on polymer films by nanoimprinting,and the films were used on the commercial silicon based solar panel by common encapsulated technology. The hierarchical nanostructure was comprised of a hexagonal microlens array of approximately 30 μm and 200 nm lattice arrays. The power generations of commercial silicon solar cells were enhanced about 4% by utilizing the hierarchical nanostructures.It has good application prospects.
