Abstract :
Compared to conventional solar cells on a substrate, thin film GaAs cells show a higher efficiency at a lower thickness due to back surface reflection. The optimal cell thickness is 1.7 /spl mu/m. Thin film cells can also be illuminated from the rear side with an efficiency only 15% (relative) lower than for front side illumination.
