Challenge: Use of copper oxide as a semiconductor in solar cells promises to reduce fabrication and material cost of photovoltaics. Despite this, the highest reported actual energy conversion efficiency is less than 5%, and as such is not yet competitive on the market for most applications as compared to existing silicon-based cells.
Technology: This technology employs low-cost electrodeposition of metal oxide films and boosts solar energy conversion efficiency by interdiffusing metal oxide layers at the p-n junction to form multiple gradient bandgap structures without dopants.
Low fabrication cost and resource efficiency.
Thin form factor.
