This paper reports an organic-inorganic hybrid solar cell with a hierarchical surface composed of high density silicon nanoholes and micro-desert textures. High-efficiency organic-inorganic hybrid solar cell Si/PEDOT-PSS with a hierarchical surface, showing a power conversion efficiency of 12%. The structure provides excellent light absorption over 97% for the spectral range of 300 to 1100 nm with a thickness of 60 μm due to internal multiple reflections caused by subwavelength features of high density silicon nanoholes and micro-desert textures. In addition, from the angle of incidence (AOI) observed, even at the large angle of 75°, the reflectance value still exhibits less than 1%. With the advantage of very thin silicon material and inexpensive processing, hybrid silicon/polymer solar cells are promising for various applications and thus could be an economically feasible alternative energy solution in the future.
本文报道了一种具有高密度硅纳米孔和微沙漠纹理的分层表面的有机-无机杂化太阳能电池。具有分层表面的高效有机-无机杂化太阳能电池 Si/PEDOT-PSS，其功率转换效率为 12%。该结构由于高密度硅纳米孔和微沙漠纹理的亚波长特征引起的内部多次反射，在 300nm 至 1100nm 的光谱范围内提供了超过 97%的优异光吸收，厚度为 60μm。此外，从入射角（AOI）观察，即使在 75°的大角度下，反射率值仍小于 1%。由于具有非常薄的硅材料和廉价的处理工艺的优势，混合硅/聚合物太阳能电池在各种应用中具有广阔的前景，因此在未来可能是一种经济可行的替代能源解决方案。
