Gradient Alloyed Metal Oxide Photovoltaics

Description:

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.

 

Advantages: 

Low fabrication cost and resource efficiency.

Thin form factor.

 

Intellectual Property Protection: 

Provisional US patent application filed.
