Unveiling The Mechanism: Decoding The Secrets Of Photocell …
Photocells, also known as photoresistors, convert light into electrical energy based on the photoelectric effect. When photons strike a light-sensitive material, usually a semiconductor, electrons are emitted. These emitted electrons generate an electric current between the cathode (electron emitter) and the anode (electron collector). The current''s …

Photocatalytic Oxygen Evolution from Water Splitting
Since the effect of doping can be affected by the types of element, it is interesting to investigate the influence of the valence state of doped elements in photocatalysts. As shown in Figure 27f, the O 2 evolution rates of TiO 2 doped with W 6+, Ta 5+, or Nb 5+ were higher than that of the pristine TiO 2, while doping of Zr 4+, Sn 4+, or Ge 4+ had little effect on the photocatalytic ...
