Abstract The average particle coordination number, one of the characters concerning the pore size distribution in the films, was introduced in dye-sensitized solar cell (DSC) modules with the size of 15cm × 20cm and the active area of 187.2cm² to estimate the performance of a TiO₂ nanoporous film, which is critical to the future DSC production. The current--voltage measurement of the DSC modules indicates that the average particle coordination number in the range of 4--5 typically appears in nanocrystalline TiO₂ films used in the DSC modules and that the average coordination number could provide a very valuable way to evaluate the performance of nanoporous TiO₂ films.
