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
