Enhanced Photovoltaic Efficiency by Heterojunction Assisted Impact Ionization
Charge multiplication by impact ionization (II) produces ~1% of the photogenerated charge in silicon photovoltaic (PV) devices under solar illumination and ~30% for photons above the silicon direct band gap. Despite these observations, few efforts have been reported to find materials and structures that optimize the rate of II and thereby conve...
