Which outcome occurs when rapid cooling induces defects within polycrystalline photovoltaic thin films?

💡 Explanation

Reduced power occurs due to increased grain boundary surface area; grain boundary recombination *mechanism* reduces carrier lifetimes. The process of carrier recombination loses free electrons, therefore lowering current, because the overall efficiency drops, rather than improved characteristics under different fabrication methods.
