http://dx.doi.org/10.29088/sami/AJCA.2019.2.2144

Abstract
  A remarkable source of renewable energy is the Dye-­sensitized solar cells (DSCs). However, the major limitation of power conversion efficiency (PCE) of devices is their inability to produce electricity using photons from the near­infrared (NIR) spectral region. Some Metal-free organic sensitizers ...  Read More
