Abstract
Low-temperature-processed carbon-based perovskite solar cells (C-PSCs) are a potential candidate for industrial development, due to their low cost, high stability, and easy preparation methods. However, their power conversion efficiencies still lag behind that of metal-contact-based PSCs, due to poor compatibility of the carbon electrode with the underlying layers. Here, we introduce a doping-free poly(3-hexylthiophene) (P3HT) hole-transport layer deposited from chloroform to improve solar cell performance of PSCs that are prepared in ambient air. The resulting P3HT films have a lower roughness and a higher conductivity. A champion device with power conversion efficiency of 19.4% was obtained with negligible hysteresis and a remarkably enhanced fill factor (FF) of 80.2%. Unencapsulated devices maintained 70% of initial efficiency value after 350 hr under thermal stress at 85°C in dark and ambient air.

期刊介绍：
Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
