Organic Photovoltaics (OPVs) have attracted considerable attention as a promising alternative
to traditional silicone based solar cells due to its mild nature, mechanical flexibility and low costs, capacity
to build large areas. This review focuses on the photovoltaic performance of organic semiconductors
produced through spin coating technology, which is a widely used statement method in OPV research. It is
emphasized that spin coating parameters such as spin speed, solvent system and additive use affect active
layer data and, in turn, affect the device efficiency and stability. Donor acceptor systems such as PM6: Y6
and PTB7-Th: PC71BM are discussed in relation to their optical properties, compatibility with transport
behaviour and spinning coating. Recent studies demonstrate that optimized spin coating procedures can
achieve power conversion efficiencies that exceeds 17% in non-fullerene based OPVs. In addition, paper
that undergoes characteristic techniques is often used to assess the quality and device performance for the
film, including UV-V is spectroscopy, AFM, SEM and J-V analysis. The review also addresses current
challenges such as scalability, environmental impact and processing of reproducibility. Overall, this work
provides a broad understanding of how spin coatings affect the performance of organic solar cells and
outlines directions for future research and development.
