Broad processing window (atmospherically applicable and scale-up) for efficient and stable perovskite solar devices/modules. Buried interface in perovskite solar cells (PSCs) is currently a highly focused study area due to their impact on device performance and stability. However, it remains a major challenge to rationally design buried interfaces.
Here we report a molecular hybrid at the buried interface in inverted perovskite solar cells that co-assembled the popular self-assembled molecule [4- (3,6-dimethyl-9 H -carbazol-9-yl)butyl]phosphonic acid (Me-4PACz) with the multiple aromatic carboxylic acid 4,4′,4″-nitrilotribenzoic acid (NA) to improve the heterojunction interface.
Buried interface has a profound influence on perovskite photostability. Passivation-free perovskite solar cells maintain 80 % efficiency after 47 days of light exposure. All-vapor-deposited perovskite solar cells (PSCs) offer promising potential for maintaining high efficiency across large-area solar modules.
Robust transporting layers do not guarantee durable perovskite solar cells. Vapor deposition promotes the structural orientation of perovskite polycrystal. Surface polarity dictates perovskite crystallography by precursor adhesion property. Buried interface has a profound influence on perovskite photostability.
Interfaces are crucial factors in perovskite solar cells (PSCs), determining carrier separation, transport, collection, and recombination. The buried interface shows serious defects that are challenging to address directly, thus attracting researchers' attention.
The cells were illuminated by a xenon lamp solar simulator (Solar IV-150A, Zolix) under air mass 1.5 G irradiation (100 mW cm −2), which was calibrated by a Newport calibrated KG5-filtered silicon reference cell.
