‘Graphene’ can solve the Rainy Day Riddle of Solar Power

Dilemma of solar power working on nights or during inclement weather has given hesitant reasons to rely on this source of green energy. As technology leapfrogs rainy days might also not affect the potential of solar. Researchers are undergoing revolutionary experiments with the wonder material ‘graphene’ (its potential has defined new dimensions in semiconductors too) […]
