Hong Kong researchers achieved a conversion efficiency of 17% with a CIGS solar cell that is thin and portable. Thin-film solar cells can be installed on roofs and outer walls and can also be integrated into consumer products such as handbags and backpacks for charging electronic products instantly.
CIGS solar cell has the highest efficiency, comparable to crystalline solar cell, yet 50 times thinner and fabrication costing 50% less. When mass production technology matures and becomes widely adopted, we believe that CIGS will be the most cost competitive solar cell, demonstrating bright market prospects.”
