We demonstrated the performance of inverted CH3NH3PbI3 perovskite-based solar cells (SCs) with a thermally oxidized nickel/gold/copper (Ni/Au/Cu) trilayer transparent electrode. Oxidized Ni/Au/Cu is a high transparent layer and has less resistance than the oxidized Ni/Au layer. Like the oxidized Ni/Au layer, oxidized Ni and Cu in oxidized Ni/Au/Cu could perform as a hole transport layer of the perovskite-based SCs. It leads to improved perovskite SC performance on an open circuit voltage of 1.01 V, a short circuit current density of 14.36 mA/cm2, a fill factor of 76.7%, and a power conversion efficiency (η%) of 11.1%. The η% of perovskite SCs with oxidized Ni (10 nm)/Au (6 nm)/Cu (1 nm) improved by approximately 10% compared with that of perovskite SCs with oxidized Ni/Au.

具有氧化Ni/Au/Cu透明电极的高效CH3NH3PbI3钙钛矿/富勒烯平面异质结混合太阳能电池

我们展示了具有热氧化镍/金/铜 (Ni/Au/Cu) 三层透明电极的倒置 CH3NH3PbI3 钙钛矿基太阳能电池 (SC) 的性能。氧化的 Ni/Au/Cu 是高透明层，电阻比氧化的 Ni/Au 层低。与氧化的 Ni/Au 层一样，氧化的 Ni/Au/Cu 中的氧化 Ni 和 Cu 可以作为钙钛矿基 SCs 的空穴传输层。它在 1.01 V 的开路电压、14.36 mA/cm2 的短路电流密度、76.7% 的填充因子和 11.1% 的功率转换效率 (η%) 下提高了钙钛矿 SC 性能。与具有氧化 Ni/Au 的钙钛矿 SCs 相比，具有氧化 Ni (10 nm)/Au (6 nm)/Cu (1 nm) 的钙钛矿 SCs 的 η% 提高了约 10%。
