Understanding the design principles of organic sensitizers for highly efficient dye sensitized solar cells

Abstract The conversion of solar to electrical power has presented itself as a solution to meet the growing energy demand and replace our current fossil fuel dependence, which causes dramatic damages to the environment. At the heart of this challenge lies ...
