论文摘要
具有透明电极的钙钛矿太阳能电池（PSC）可以与串联配置中的现有太阳能电池板集成，以提高功率转换效率。半透明的PSC中的临界层是无机缓冲层，它在将透明电极溅射到顶部时可以保护PSC免受损伤。缺乏合适的P型缓冲层层，N-I-P结构半透明的PSC的发展受到了阻碍。 In this work we develop a p-type CuOx buffer layer, which can be grown uniformly over the perovskite device without damaging the perovskite or organic charge transport layers, can be grown using industrially scalable techniques and has high hole mobility (4.3 +/- 2 cm2 V-1 s-1), high transmittance (>95%), and a suitable ionisation potential for hole extraction (5.3 +/- 0.2 EV）。使用Cuox缓冲层可实现效率高达16.7％的半透明PSC。我们的工作展示了一种将PSC集成到串联配置中的新方法，并可以开发需要高质量P型层的其他设备。
Perovskite solar cells (PSCs) with transparent electrodes can be integrated with existing solar panels in tandem configurations to increase the power conversion efficiency. A critical layer in semi-transparent PSCs is the inorganic buffer layer, which protects the PSC against damage when the transparent electrode is sputtered on top. The development of n-i-p structured semi-transparent PSCs has been hampered by the lack of suitable p-type buffer layers. In this work we develop a p-type CuOx buffer layer, which can be grown uniformly over the perovskite device without damaging the perovskite or organic charge transport layers, can be grown using industrially scalable techniques and has high hole mobility (4.3 +/- 2 cm2 V-1 s-1), high transmittance (>95%), and a suitable ionisation potential for hole extraction (5.3 +/- 0.2 eV). Semi-transparent PSCs with efficiencies up to 16.7% are achieved using the CuOx buffer layer. Our work demonstrates a new approach to integrate PSCs into tandem configurations, as well as enable the development of other devices that need high quality p-type layers.
