Abstract
With the rapid rise of the internet of things (iot), organic solar cells (oscs) are increasingly sought for indoor applications due to their lightweight design, easy fabrication, and adaptability to indoor settings. However, morphology control of the oscs remains challenging due to variations in film-drying kinetics across fabrication methods. Recently, solid additives have shown promise in improving morphology, streamlining post-treatment, and enhancing stability, making them a preferred approach for optimizing oscs. Therefore, this study focused on fabricating p3ht:pcbm-c71-based oscs incorporated with solid additives (2,3-dhp) for indoor photovoltaic (ipv) applications, using pedot:pss as a hole transport layer (htl) and zno nps:alq3 as an electron transport layer (etl). The work was divided into four main parts: in the first part, composition optimization was achieved by adjusting the concentration of p3ht and pcbm using a solution-processing technique. The optimal morphology and crystallinity were observed in the 1:1 ratio blend using a co-solvent of 1,2-dichlorobenzene (dcb) annealed at 100 °c, resulting in a power conversion efficiency (pce) of 1.7% (as a reference device).
