6 FAQs about [Why is the surface of photovoltaic panels rough ]

How does surface roughness affect perovskite growth?

Surface roughness emerges as highly important, affecting the perovskite growth drastically, with the smooth substrate (ITO) exhibiting more monolithic film formation.

What is the surface roughness and contact angle of perovskite solution?

Table 1 Surface roughness and contact angle of perovskite solution on ITO, polished FTO, and FTO. The measured contact angle for a polished FTO substrate is 58.0° ± 1.19°, which lies between the surface roughness of FTO and ITO.

Which substrate has less surface roughness?

In contrast, the crystals on the smooth ITO substrate are more distinct and block-like. The grain boundaries tend to go from the bottom to the top contact. We checked our hypothesis on a polished FTO substrate, which has less surface roughness.

Can flexible perovskite solar be highly efficient?

We posit that one of the main challenges for achieving highly-efficient flexible perovskite solar is the different surface roughness. Most rigid PSCs have been processed on FTO, which is unsuitable for flexible PSCs as it requires a high processing temperature when manufactured. It is, therefore, necessary to change from FTO to ITO.
