This review focuses on different types of third-generation solar cells such as dye-sensitized solar cells, Perovskite-based cells, organic photovoltaics, quantum dot solar cells, and tandem solar cells, a stacked form of different materials utilizing a maximum solar spectrum to. Third-generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells. This includes a range of alternatives to cells made of semiconducting p–n junctions ("first generation") and thin-film. Solar energy has become an increasingly popular source of renewable energy in recent years, with advancements in technology leading to the development of more efficient solar cells. Third-generation solar cells are the latest innovation in this field, offering improved performance and capabilities. Third-generation solar cells are designed to achieve high power-conversion efficiency while being low-cost to produce. These solar cells have the ability to surpass the Shockley–Queisser limit. Four main approaches are highlighted: multi-junction cells, intermediate-band cells, hot carrier cells and spectrum conver-sion. These cells aim for higher efficiencies using modern chemicals and technologies while minimizing manufacturing costs.
