Numerical investigation on efficiency enhancement and influence of electrical parameters on PBDBT-INTIC bulk heterojunction organic solar cells.

Non-fullerene acceptor (NFA) based bulk heterojunction organic solar cells (BHJOSC) offer a promising pathway for advancing organic photovoltaic (OPV) technology. These solar cells have the potential to improve performance and offer greater versatility in material design. Due to their broad absorption spectra, tunable energy levels, and reduced energy loss, researchers are actively exploring NFA materials and device architectures to further enhance the efficiency and viability of these solar cells. In this study, we focus on efficiency enhancement and investigating the influence of varying bandgap, thickness, and electron affinity of (PBDBT) Poly[[4,8-bis[5-(2-ethylhexyl)-2-thienyl]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl]-2,5-thiophenediyl[5,7-bis(2-ethylhexyl)-4,8-dioxo-4H,8H-benzo[1,2-c:4,5-c′]dithiophene-1,3-di yl]]/-2,2'-((2Z,2'Z)-((6,6'-(5,10,10-tris(2-ethylhexyl)-5,10-dihydroindeno[1,2-b]indole-2,7-diyl)bis(2-octylthieno[3,4-b]thio-phene-6,4-diyl))bis(methanylylidene))bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1diylidene))dimalononitrile (PBDBT-INTIC) based NFABHJOSC with the incorporation of graphene derivative in the hole transport layer (HTL) and electron transport layer (ETL). To conduct our research, we utilize a One-Dimensional Solar Cell Capacitance Simulator (SCAPS1D) for simulation studies. Additionally, we also examine the impact of varying the work function of anode in our investigation. This comprehensive study aims to provide valuable insights into the performance and characteristics of NFABHJOSC, contributing to the advancement of organic photovoltaic technology [ABSTRACT FROM AUTHOR]
