We investigated a range of different mesoporous NiO electrodes prepared by different research groupsand private firms in Europe to determine the parameters which influence good quality photoelectrochemicaldevices. This benchmarking study aims to solve some of the discrepancies in the literature regarding theperformance of p-DSCs due to differences in the quality of the device fabrication. The informationobtained will lay the foundation for future photocatalytic systems based on sensitized NiO so thatnew dyes and catalysts can be tested with a standardized material. The textural and electrochemicalproperties of the semiconducting material are key to the performance of photocathodes. We found thatboth commercial and non-commercial NiO gave promising solar cell and water-splitting devices. TheNiO samples which had the two highest solar cell efficiency (0.145% and 0.089%) also gave the bestoverall theoretical H2 conversion.
