UNLABELLED
In recent years, inorganic/organic hybrid solar cell concept has received growing attention for alternative energy solution because of the potential for facile and low-cost fabrication and high efficiency. Here, we report highly efficient hybrid solar cells based on silicon nanowires (SiNWs) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (
PEDOT
PSS) using transfer-imprinted metal mesh front electrodes. Such a structure increases the optical absorption and shortens the carrier transport distance, thus, it greatly increases the charge carrier collection efficiency. Compared with hybrid cells formed using indium tin oxide (ITO) electrodes, we find an increase in power conversion efficiency from 5.95% to 13.2%, which is attributed to improvements in both the electrical and optical properties of the Au mesh electrode. Our fabrication strategy for metal mesh electrode is suitable for the large-scale fabrication of flexible transparent electrodes, paving the way towards low-cost, high-efficiency, flexible solar cells.

近年来，无机/有机混合太阳能电池概念因其易于低成本制造和高效率的潜力，在替代能源解决方案方面受到越来越多的关注。在此，我们报告了基于硅纳米线（SiNWs）和聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS），使用转移压印金属网前电极的高效混合太阳能电池。这种结构增加了光吸收并缩短了载流子传输距离，因此，大大提高了电荷载流子收集效率。与使用氧化铟锡（ITO）电极形成的混合电池相比，我们发现功率转换效率从5.95%提高到了13.2%，这归因于金网电极的电学和光学性能的改善。我们的金属网电极制造策略适用于大规模制造柔性透明电极，为低成本、高效率、柔性太阳能电池铺平了道路。
