Why does a photovoltaic module have a low shunt resistance?

The electrical performance of a photovoltaic (PV) module is greatly hindered by the existence of parasitic resistance losses, such as high series resistance (R s ) and low shunt resistance (R sh ). Contact resistance at metal grid/semiconductor interface and emitter sheet resistance are two major contributors to cell R s .
