I need to find out the thickness of my perovskite thinfilm via Landau-levich equation. To calculate, I need to have viscosity and density of my perovskite solution. Is there anyone to help me?
I want to measure the thickness of tio2 mesoporous, perovskite and HTM layers in my perovskite solar cell samples accurately with FESEM images. but I dont know how to prepare my samples to avoid...
