摘要

Fast epitaxial growth is an attractive method for reducing III-V photovoltaic device cost. Here, we grow a high-performance, rear-junction GaAs solar cell at 1 µm/min via metal organic chemical vapor deposition. We integrate an epitaxial distributed Bragg reflector with the solar cell to increase the optical path length for photons near the band-edge, enhancing photon recycling without the need fo...
