Solar Cells with Extreme Absorption Capacity

Designable, Sustainable and Economical Solar Cells with Extreme Absorption Capacity

Solar power has the potential to contribute considerably to satisfying the universal energy demand, but current technologies have problems with sustainability from a life cycle standpoint and are limited both by aesthetic requirements and high cost. The key to solving this is through the development of affordable, designable, efficient, stable, and sustainable solar cells. Peafowl Solar Power is a spin-off from Uppsala University, Sweden, that has created a new kind of solar cell that exhibits promise to match these demands. The photovoltaic effect of the Peafowl Solar Cell is based on different physics that does not have the same characteristic limitations as earlier technologies.

Technology

The distinctiveness of Peafowl Solar technology is the use of plasmonic nanoparticles (LSP) as light absorbers. These structures can absorb equal to tenfold more sunlight compared to other materials. Their sunlight spectrum absorption is easily tweaked by modifying particle morphology.

In conventional photovoltaics, one photon excites one electron. In the plasmonic cell, a photon can produce several electrons because of the localized surface plasmon resonance, which is a fundamentally different mechanism. The theoretical boundaries for power generation that applies to conventional photovoltaics are thus not valid here. The cell itself comprises three layers, of which the plasmonic nanoparticles are in the middle layer. There are more than a few options for manufacturing but printing the cells looks like an economical and scalable solution.

Business Opportunities

The primary market that has been identified are low-power, off-grid applications, generally powering sensors, transmitters, processors, or displays of IoT devices. There are also opportunities associated with off-grid building integration, smart windows, airspace, automotive, and radio-frequency antennas.

Business Model

Peafowl Solar aims to develop Peafowl Solar cells for specific applications along with pilot customers and partners that can contribute with resources and expertise in up-scale manufacturing. For the future, Peafowl Solar considers licensing Peafowl Solar technology and/or selling components for the production of Peafowl Solar cells.
