A direct impact of substrate on the back contact properties of thin-film solar cells cannot be neglected in case of metallic sheets, mainly, because of roughness and impurities diffusion. In this work, the influence of substrate roughness on Mo back contact sheet resistance was preliminary studied. The roughness of different substrates was analyzed by DEKTAK 150 profilometer. Next, an advanced Mo back contact was deposited. Finally, the resulting sheet resistance of the back contact was measured by 4-point probe technique.
