Is there any specific value for Meso-TiO2 porosity, and pore size? Shouldnt it be fixed with perovskite grain size?

My meso-TiO2 pore size is about 50nm, but perovskite grain size is far more, how can they get fixed?

Aside from measuring PCE, how can I measure the quality of Spiro-OMeTAD and its performance (JUST Spiro) in perovskite solar cells?

I need to measure a parameter for evaluating Spiro layer performance, this parameter should be a quant, and just represent the Spiro performance, without Au.
