Photocurrent Generation by Polymeric Carbon Nitride Solids: An Initial Step towards a Novel Photovoltaic System

Polymeric carbon nitride, which is cheap, amenable to mass preparation and chemical modification, and highly stable against oxidation up to 550 °C in air, has been exemplified to be potentially promising as a photoactive material in directly converting solar light into electricity. It would not only strengthen the emerging applications of the kaleidoscopic carbon nitride solids, but also contribute to a more open discussion in photovoltaics.
