摘要

宽带隙(WBG)过氧化物太阳能电池(PSC)已被广泛用作串联太阳能电池的顶层电池。然而,光诱导相分离和高开路电压损耗是开发 WBG PSCs 的重大障碍。本文报告了一种分两步的小尺寸 A-位和大尺寸 X-位掺杂策略,该策略基于两步沉积法调节晶格畸变并改善 WBG 甲脒-甲基铵(FAMA)包晶石薄膜的薄膜质量,从而实现光稳定性 PSCs。首先,引入 0-20% 的 CsI 来调节带隙为 1.70 eV 的 FAMA 包晶石的晶格畸变和薄膜质量。然后,加入 4% 的 RbI 以进一步调节包晶的生长和晶格畸变,从而抑制 RbCsFAMA 四阳离子包晶中的光诱导相分离。因此,掺杂了 20%CsI/4%RbI 的器件的效率达到了 20.6%,而且相应的过氧化物薄膜显示出良好的光热稳定性。即使没有封装,该器件在 1 个太阳当量的白光发光二极管照明下连续工作 1000 小时后,仍能保持 92% 的初始效率。

Suppressed Phase Segregation with Small A-Site and Large X-Site Incorporation for Photostable Wide-Bandgap Perovskite Solar Cells.

Suppressed Phase Segregation with Small A-Site and Large X-Site Incorporation for Photostable Wide-Bandgap Perovskite Solar Cells.

Wide-bandgap (WBG) perovskite solar cells (PSCs) have been widely used as the top cell of tandem solar cells. However, photoinduced phase segregation and high open-circuit voltage loss pose significant obstacles to the development of WBG PSCs. Here, a two-step small-size A-site and large-size X-site incorporation strategy is reported to modulate the lattice distortion and improve the film quality of WBG formamidinium-methylammonium (FAMA) perovskite films for photostable PSCs based on two-step deposition method. First, CsI with content of 0-20% is introduced to tune the lattice distortion and film quality of FAMA perovskite with a bandgap of 1.70 eV. Then, 4% RbI is incorporated to further modulate the perovskite growth and lattice distortion, leading to the suppression of photoinduced phase segregation in the resultant RbCsFAMA quadruple cation perovskites. As a result, the 20%CsI/4%RbI-doped device obtains a promising efficiency of 20.6%, and the corresponding perovskite film shows good photothermal stability. Even without encapsulation, the device can maintain 92% of its initial efficiency after 1000 h of continuous operation under 1 sun equivalent white light-emitting diode illumination.
