One of the key challenges we face today is to use renewable energy sustainably. Compared to other PV technologies, CIGS technology offers enormous application and yield potential.
CIS, or CIGS, stands for the constituents copper (Cu), indium (In), gallium (Ga) and selenium (Se). The main feature of CIS technology is its wafer-thin 2µm semiconductor layer. Due to its spectral response, this is all it takes to capture the sunlight very efficiently and convert it into sustainable electrical power. By comparison, the semiconductor layer of crystalline silicon solar cells are one hundred times thicker than those of CIS solar cells. Valuable resources are also saved in the manufacture of solar cells, as CIGS technology requires much lower energy consumption than other PV technologies.
