  The photosynthetic reaction center of plants and bacteria is an extremely
efficient energy to charge conversion device. Solar photons create excitons in
the pigment molecules. These excitons are then transferred to the reaction
center where charge separation takes place. These processes - excitonic
generation and subsequent charge separation are extremely efficient with almost
unity efficiency. Taking pointers from this biophysical process, we propose a
GaN quantum dot based solid state energy to charge conversion device idea that
emulates the photosynthetic reaction center. This further suggests that highly
efficient quantum biological processes can give important pointers for
developing energy harvesting quantum technologies.
