Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have developed advanced solar cells that deliver over 40% efficiency under indoor lighting. It’s a major progress that will help run Internet of Things (IoT) devices.
These III-V semiconductor-based cells, improved using gallium indium phosphide (GaInP), perform exceptionally well even under low light conditions, such as 100 lux, according to a study published in Applied Physics Letters.
The result could bring big changes to how we power small devices indoors, especially in systems like the Internet of Things (IoT), where it’s hard to recharge batteries often.
The n-doped GaInP solar cells worked better than the p-doped ones because they hold electric charges for a longer time and can produce more electricity.
This new technology is the result of several government-supported research programs: the 50Percent project, backed by the Federal Ministry for Economic Affairs and Climate Action (BMWK); the H2Demo project, funded by the Federal Ministry of Education and Research (BMBF); and the SMART project, which was created together with AZUR SPACE and the German Space Agency DLR.
These efforts show Germany’s strong dedication to developing advanced solar technologies for future generation applications.
