This paper introduces a novel approach to conventional Photovoltaic (PV) modules that involves regulating the internal connections of the PV strings (or submodules) using a set of switches to isolate shaded submodules while leaving unshaded submodules unaffected. By extending the connection types of the PV submodules to include parallel or series v...

The COVID-19 pandemic has had a significant impact worldwide, impacting schools, undergraduate, and graduate university education. More than half a million lives have been lost due to COVID-19.

This article describes the spatial variations of the shunt resistance in a-Si:H, PV cells across the absorber layer (i-layer).
