From bio-solar cells and floating solar farms to energy harvesting trees and transmission of power from space, the future looks quite bright for renewable energy

Bio-solar cells

For the first time ever, researchers connected nine biological-solar (bio-solar) cells into a bio-solar panel and continuously produced electricity from the panel and generated the most wattage of any existing small-scale bio-solar cells.

Last year, the group took steps towards building a better bio-solar cell by changing the materials used in anodes and cathodes (positive and negative terminals) of the cell and also created a miniature microfluidic-based single-chambered device to house the bacteria instead of the conventional, dual-chambered bio-solar cells.

However, this time, the group connected nine identical bio-solar cells in a 3x3 pattern to make a scalable and stackable bio-solar panel. The panel continuously generated electricity from photosynthesis and respiratory activities of the bacteria in 12-hour day-night cycles over 60 total hours................Read more
