This critical review traces the historical evolution and technological advancement of PV systems, emphasizing key innovations across various photovoltaic cell types such as crystalline silicon, amorphous silicon, cadmium telluride, perovskites, and organic materials. . Solar photovoltaic (PV) technology stands as a central pillar in the global shift toward renewable energy. However, its large-scale deployment continues to be hindered by notable technical and economic constraints. These advancements. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power.
