CIGS Solar Cells Minimize Solar Energy Costs

DayStar Technologies develops CIGS solar cells. These solar cells are known as copper-indium-gallium-di-selenide cells and are manufactured as thin films. CIGS solar cells are designed for converting sunlight into electricity directly and can minimize solar energy costs.

These solar cells have been manufactured by combining semiconductor material with layers of other materials. The net result is the formation of a solar cell with a photovoltaic effect that can generate electricity from sunlight. The solar cell is converted to a solar module by placing different cells on glass substrates. CIGS solar modules are formed from CIGS solar cells by employing the process of monolithic integration.

The monolithic integration technology used for producing CIGS solar modules involves formation of individual cells using delineating process scribes. This method, which requires interconnection of the individual solar cells, is possible when a non-conducting substrate such as glass is used. CIGS solar cells provide a higher performance when compared to other silicon and cadmium telluride materials because of its higher conversion efficiency. Solar cells and modules manufactured with CIGS can be used in any kind of photovoltaic system and mounting system.
