The cell isdesigned for use in concentrating PV (CPV), a technology that achieves more than twice theefficiency of conventional PV power plants in sun-rich locations, Fraunhofersays.
“Thisfour-junction solar cell contains our collected expertise in this area overmany years. Besides improved materials and optimisation of the structure, a newprocedure called wafer bonding plays a central role,” says Frank Dimroth,project leader at Fraunhofer ISE in charge of the development.
