High-efficiency solar cell development at the Fraunhofer ISE
Abstract
An overview of the high-efficiency solar cell development at Fraunhofer ISE is given. Five types of cells are discussed: (1) the LBSF (= local back surface field) cell, (2) the RP-PERC (= passivated emitter and rear cell with random pyramids), (3) the MESC (= mesh-structured emitter solar cell), (4) the RCC (=rear contacted cell) and (5) the high-efficiency thin film cell based on SO1 (= silicon on insulator). All these cells show very good efficiencies near and above 20 %.
