Integration of Sustainable Carbon Nanoparticles Into Inverted Hybrid Perovskite Solar Cells to Enhance Optoelectronic Performance.

ABSTRACT: Hybrid Perovskite Solar Cells (HPSCs) using lead halide perovskites offer high performance and low-cost fabrication via solution processes. However, their environmental and thermal instability, along with poor polycrystalline quality-such as trap states and grain boundaries-limit device efficiency. In this study, we propose four novel compositions of carbon nanoparticles (CNPs) as additives for methylammonium PbI₃ (MAPI)-based HPSCs to enhance the optoelectronic performance. The CNPs are synthesized through a green, cost-effective method using citric acid and L-tryptophan for nitrogen doping. Their optical, structural, and morphological properties are thoroughly characterized prior to integration. To assess the impact of CNPs on perovskite crystallization and facet orientation,
