In harnessing photosynthesis to produce green energy, the native photosynthetic system is interfaced with electrodes and electron mediators to yield bio-photoelectrochemical cells (BPECs) that transform light energy into electrical power. Researchers from the National Research and Innovation Agency (BRIN) showed a battery cell developed using the photosynthesis protein complex reaction center-light harvesting 1 (RC-LH1) from purple bacteria as the light-absorbing layer in the solar cell device. With the accelerated advancement of solar-driven CO 2. Photosynthetic solar panels are an innovative technology that converts sunlight into energy while mimicking the natural process of photosynthesis observed in plants. They harness solar energy effectively, 2. Senior Scientist, Chemical Biodynamics Division, Lawrence Berkeley Laboratory, University of California, Berkeley, 1978–86; Research. Photosynthesis[note 1] is a system of biological processes by which photopigment -bearing autotrophic organisms, such as most plants, algae and cyanobacteria, convert light energy — typically from sunlight — into the chemical energy necessary to fuel their metabolism.
