Studies on the impact of panel shading on PV system output have long focused on large modules. Now, Chinese researchers are shifting the focus to single cells and two cells connected in series or in ...

Researchers from Trina Solar and China’s Nanchang University claim to have verified that back-contact solar modules outperform TOPCon modules only when fewer than three cells in a substring are shaded ...

Because cell shading gave them the graphical look they were after? I don't think I get the question, why do you think some other technique should have been used?
