Solar Cells and Artificial Photosynthesis Make Hydrogen Directly

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Science 2.0.com reports on an exciting potential breakthrough in solar energy and its direct transformation into hydrogen fuel.  Usually, solar cells generate current from photons, making electricity which can run things or be stored in batteries. This new and different approach, using an innovative and inexpensive solar cell and a metal oxide photo anode, can store nearly five percent of solar energy chemically as hydrogen. The metal oxide bismuth vanadate (BiVO4) photo anode includes a small dose of tungsten atoms, was then sprayed onto conducting glass and “coated with an inexpensive cobalt phosphate catalyst,” which helped speed up oxygen formation during water splitting. Science 2.0 reports Professor Dr. Roel van de Krol’s remarks.  He’s head of the Helmholtz Zentrum Berlin …
