Reverse-bias protected thin-film solar resists local shading/ maintains 97% operational efficiency over 2K hours of continuous stress

"solar panels suffer degradation/ efficiency loss as unshaded sections force current through shaded cells causing localized overheating, overcome redistributing electrical current under non-uniform illumination while preserving core photovoltaic performance... this structural mitigation provides a viable framework for mass-producing durable, highly efficient solar arrays for urban, residential, and transport applications where intermittent shading is unavoidable"
