Photovoltaic Cell from Thermophilic Cyanobacteria

Photochemical nanoelectrode stable up to 80°C

 

Categories	Energy, Optoelectronics/Photonics, Nano Structures, Cleantech
Development Stage	Advanced research stage – proof of concept
Patent Status	Pending
Market	Global nanoelectronics market to reach $409.6 billion by 2015. Integration of molecular biology and nanoelectronics creates avenues for developing hybrid devices for utilization in a wide range of biological and medical applications.

Highlights

• System that uses the natural photosynthetic light-harnessing system of cyanobacteria to convert light to electricity or fuels.
• In vitro system derived by isolating the photosynthetic complex from native bacteria that grow in hot springs and adding platinum to convert light into electric current or fuels.
• Combines nanotechnology, complex chemistry, and biotechnology to produce a functional biological molecule
• Significant current already achieved - >2µA/cm2 of electrode surface with relatively high efficiency (5%)

Our Innovation
