German semiconductor maker Infineon has announced a reduction in losses during the three months to June.

BBC: Infineon losses narrow

The CO2 reduction takes place on a metal catalyst at the opposite side of nitride semiconductor photo-electrode.(See Fig. 1) The metal catalyst plays an important role in selecting and accelerating the reaction.
