摘　　要：Si hybrid solar cells have attracted tremendous research attention in recent years because of their low production costs and high performance. However, flexible Si hybrid solar cells have rarely been reported owing to the difficulty of fabricating single-crystalline Si with good flexibility. In this study, we fabricated flexible Si/PEDOT：PSS hybrid solar cells with micro-pyramid-structured Si light absorbers using a facile approach. Compared with planar flexible hybrid solar cells with a power-conversion efficiency of 4%, solar cells with micro-pyramid-structured Si light absorbers have a higher efficiency of 6.3%. External quantum efficiency and electrochemical impedance spectroscopy measurements revealed that the solar cells with micro-pyramid-structured Si light absorbers exhibited a pronounced light-harvesting enhancement in the spectra region of 400-1,000 nm and had a smaller series resistance and larger recombination resistance compared with the planar cells, yielding a higher efficiency. Additionally, in mechanical-bending tests, the flexible solar cells with micro-pyramid-structured Si light absorbers exhibited an excellent performance stability after bending for 600 cycles. Our findings lay the foundation for the real-world applications of flexible Si/PEDOT：PSS hybrid solar cells in next-generation portable electronics.因为他们的低生产费用和高效， Si 混合太阳能电池在最近的年里吸引了巨大的研究注意。然而，灵活 Si 混合太阳能电池很少由于与好灵活性制作单人赛水晶的 Si 的困难被报导了。在这研究，我们制作了灵活 Si/PEDOT : 有用一条灵巧的途径的 micro-pyramid-structured Si 轻吸收器的 PSS 混合太阳能电池。与有 4% 的力量变换效率的平面灵活混合太阳能电池相比，有 micro-pyramid-structured Si 轻吸收器的太阳能电池有 6.3% 的更高的效率。外部量效率和电气化学的阻抗光谱学大小表明有 micro-pyramid-structured Si 轻吸收器的太阳能电池在 4001,000 nm 的系列区域展出了显著轻收获的改进并且与平面房间相比有一个更小的系列电阻和更大的再结合抵抗，产出更高的效率。在机械弯曲的测试，另外，有 micro-pyramid-structured Si 轻吸收器的灵活太阳能电池在为 600 个周期弯曲以后展出了优秀表演稳定性。我们的调查结果为灵活 Si/PEDOT 的真实世界的应用程序打了基础: 在下一代的便携式的电子学的 PSS 混合太阳能电池。
