As the economy grows rapidly, energy demand increases. The main types of energy used are non-renewable, notably fossil fuels and nuclear energy. The depletion of fossil fuels, environmental pollution, and global warming caused by burning fossil fuels are also raising serious concerns. In the current climate change situation, exploiting renewable energy sources, particularly solar photovoltaics, has become a priority. Solar energy has the highest potential of all renewable resources, with the Earth's surface receiving enough energy from the sun in just one hour to meet humanity's energy requirements for a year. As solar energy is infinite and clean, solar cells can be used in everyday life to convert sunlight directly into electricity. Solar cells can be categorised into four generations using green chemistry and new materials.

This collection focuses on the latest advancements in new materials and thin-film solar cells. It showcases cutting-edge research in material synthesis, structural characterisation, physicochemical evaluation, simulation, and theoretical modelling.

The journal welcomes original research articles, reviews, and perspectives from academia and industry. Manuscripts should adhere to journal guidelines and undergo rigorous peer review.

Keywords: Organic-Inorganic Thin Film Solar Cells; Numerical Simulation; Green Chemistry; Sustainable Energy Materials; Photovoltaic Efficiency; Novel Materials Design; Perovskite Solar Cells; Material Synthesis and Structural Characterisation; Theoretical Modelling; Tandem Solar Cells.

This Collection supports and amplifies research related to SDG 7 and SDG 9.
