Always scientists around the world have been trying to create a low cost solar cell that is both efficient and easy to manufacture.
The purpose is to make solar energy affordable for the common people.
Swiss researchers from Swiss Federal Laboratories for Materials Science and Technology’s (EMPA) Laboratory for Thin Film and Photovoltaics have established a new world record efficiency of 18.7% for flexible copper indium gallium (di)selenide (CIGGS) solar cells on plastics.
This new discovery has the potential to lower the cost of solar energy drastically because they are cheaper to produce and this latest breakthrough brings them closer to the highest efficiency levels achieved by crystalline silicon and rigid CIGS cells.
These highly efficient solar cells will drop the cost of solar energy and make them ideal for use in demanding applications such as solar facades and portable electronic devices.
