The plasmonic electrodes can enhance the performance of PEC devices for electricity generation as well as water splitting by using more light. The plasmonic electrodes have more advantages than doped or dye sensitized electrodes. The PEC devices have lower efficiency upto 1%–5% [77]. The plasmonic TiO2 cell deposited with gold plasmonic nanoparticles at top surface has shown light to energy conversion efficiency of about 0.01%– 0.02% [78]. The photosensitization of plasmonic nanoparticles Lee et al. have made plasmonic photoanode using gold nanorod ceiled with semiconducting TiO₂ for solar to hydrogen (H₂) generation and achieved efficiency about 40% under visible light [88] Plasmonic Au nanoparticles act as a photosensitizer in PEC devices. This technology is still at laboratory scale. The device configuration and modifications in photoactive layers are needed to improve the efficiency in PEC cells [80].
