Economical eco-friendly fabrication of high efficiency chalcopyrite solar cells

Clean, sustainable energy solutions are essential to meet the ever-increasing energy demands of the human population. High efficiency solar cells are promising candidates to reduce carbon emissions and achieve carbon neutrality. In this regard, solution-processed copper indium gallium sulfur diselenide solar cells (CIGSSe) solar cells have generated significant interest owing to their excellent photovoltaic properties, such as high absorption of visible light, stability, and tunable bandgap.
