Abstract :
In this work, the authors describe the fabrication and operating characteristics of GaAs/AlGaAs thin-film solar cells using the epitaxial liftoff (ELO) technique. This technique allows the transfer of these solar cells onto nonabsorbing glass substrates, and makes possible light-trapping operation. The enhanced performance of the lifted-off solar cell is demonstrated by means of electrical measurements under both dark and illuminated conditions
