Maturing effects in carbon‐based perovskite solar cells: understanding and consequences on photovoltaic performances

Résumé

Recent investigations have highlighted the potential of post‐treatments to enhance the performance of specific perovskite solar cells, notably focusing on those incorporating carbon‐based materials (C‐PSC). However, the precise mechanisms underpinning this performance boost remain somewhat elusive. This study aims to delve deeper into the maturation phenomenon observed in C‐PSC, concentrating on two distinct methods of perovskite deposition: drop casting and inkjet printing. Upon subjecting the cells to the maturation process, a noteworthy elevation in power conversion efficiency (PCE) becomes evident. Specifically, drop‐cast cells exhibited a PCE advancement from 10.5% to 14%, while inkjet‐printed cells showcased an improvement from 10% to 14%. In the context of drop‐cast cells, characterized by a relatively thicker and spatially heterogeneous perovskite layer, maturation primarily prompted alterations within the perovskite layer itself. Conversely, in the realm of inkjet solar cells boasting a thinner yet more uniform active layer thickness, maturation exerted distinctive impacts, primarily manifesting at the interfaces. The observed maturation phenomenon exhibits a profound dependence on the solar cell’s architecture and morphology, underscoring the pivotal role of these aspects in determining the ensuing effects. These revelations offer illuminating insights into the intricate dynamics of perovskite solar cells and offer valuable guidance for the ongoing refinement of their performance.
