A group of scientists from the Helmholtz-Zentrum Berlin research institute and the Delft University of Technology have created a solar fuel device that is economical, steady, and efficient. The technology utilises a solar cell and a photo anode fashioned from metal oxide. Bismuth vanadate metal oxide, which is inexpensive and inert, was used in conjunction with a silicon-based thin film solar cell. Artificial photosynthesis was then executed, causing the water to break down into hydrogen and oxygen, leading to chemical energy storage.
A number of steps were taken to increase the efficiency of the entire process. One of them was the separation of charges and splitting of the water molecules to improve light absorption. They are now hard at work scaling up the technology in order to yield higher quantities of hydrogen.
