Application of metal, metal-oxide, and silicon-oxide based intermediate reflective layers for current matching in autonomous high-voltage multijunction photovoltaic devices

A logical next step for achieving a cost price reduction per Watt peak of photovoltaics (PV) is multijunction PV devices. In two-terminal multijunction PV devices, the photo-current generated in each subcell should be matched. Intermediate reflective layers (IRLs) are widely employed in multijunction devices to increase reflection at the...
