In the quest to develop efficient semitransparent perovskite solar cells (ST-PSCs), the primary challenge lies in transparent electrode fabrication. n–i–p-type ST-PSCs often suffer from low fill factors (FF) and power conversion efficiency (PCE), attributed to the undesirable buffer layer/transparent conductive oxide combination of the transparent electrode. In this context, this study proposes an efficient composite transparent electrode (CTE) system comprising an ultrathin MoO3 buffer layer (5 nm) and low-power sputtered indium zinc oxide (45 W–220 nm). The electrode demonstrates excellent compatibility with Spiro-OMeTAD-based devices, effectively addressing the low FF and PCE challenges of ST-PSCs. Employing the new CTE, the best-performing ST-PSCs with the absorption edge at 1.57 eV achieve a remarkable PCE of 21.96% with an FF of up to 83.80%. More transparent ST-PSCs with thickness-modulated absorbers and average transmittance of 50.77% at 600–1200 nm wavelength result in a PCE of up to 20.91% with the highest known FF of 84.02%. This study presents a general and viable approach for fabricating efficient ST-PSCs.

填充因子超过 84% 的半透明钙钛矿太阳能电池复合透明电极的受控制造

在开发高效半透明钙钛矿太阳能电池(ST-PSC)的过程中,主要挑战在于透明电极的制造。 n- i -p 型 ST-PSC 通常会遇到填充因子 (FF) 和功率转换效率 (PCE) 较低的问题,这归因于透明电极的缓冲层/透明导电氧化物组合不理想。在此背景下,本研究提出了一种高效复合透明电极(CTE)系统,包括超薄MoO 3缓冲层(5 nm)和低功率溅射氧化铟锌(45 W-220 nm)。该电极与基于 Spiro-OMeTAD 的设备具有出色的兼容性,有效解决了 ST-PSC 的低 FF 和 PCE 挑战。采用新的 CTE,吸收边缘为 1.57 eV 的性能最佳 ST-PSC 实现了 21.96% 的显着 PCE 和高达 83.80% 的 FF。更透明的 ST-PSC 具有厚度调制吸收体,在 600-1200 nm 波长下的平均透射率为 50.77%,PCE 高达 20.91%,已知的最高 FF 为 84.02%。这项研究提出了一种制造高效 ST-PSC 的通用且可行的方法。
