Problems solved by technology

There are various problems in the photoelectrodes of existing commercial photoelectrochemical electrolysis cells, such as figure 1 As shown, the photoelectrode is directly inserted into the electrolyte, and the area of ​​the electrode is often controlled by a tape mask. It is difficult to control the size of the area in actual operation, and it is difficult to compare the experimental results. In addition, the connection of the electrode needs to be fixed with conductive silver glue. The curing of the glue takes a long time, and the conductive silver glue will increase the contact potential of the electrode, which has a certain influence on the measurement of the potential

In addition, the existing photoelectrodes are sealed and fixed with flanges, and the assembly process of the photoelectrodes is relatively cumbersome. The actual operation requires an urgent need to redesign the structure of the existing photoelectrochemical cell.
