The basic concept for the future development of human society has become to reduce emissions of greenhouse gases such as carbon dioxide that cause climate change. As a result, one of the best sustainable and environmentally acceptable solutions to this challenge is to use perovskite solar cells (PSCs), which may be used as an efficient alternative for fossil fuels. The main objective of this work is to design and improve the performance of carbon quantum dot-based PSCs. We presented a simple method for modifying the physicochemical properties of hole transport layer (HTL) and electron transport layer (ETL) as the most efficient components in solar cells, using in-situ plasma surface treatment. Following that, the effects of the treatment on the microstructure, active sites, surface area, optical, and electrical characteristics of these nanolayers were examined. Whereas, these treatments resulted in a considerable improvement in the chemical functionalization of the nanolayers, as well as a rapid increase in surface roughness, which reduced photons reflection and therefore increased the generation of charge carriers.
