What is Shunt Resistance in Solar Cell? Key Concept Explained

The short-circuit current (Isc) also drops with a low shunt resistance. It sends some light-generated current elsewhere. So, less current goes through the junction, affecting the solar cell''s power output. Fill Factor (FF) A low shunt resistance hurts the solar cell''s fill factor (FF). It reduces current and voltage outputs. This means less power is available, decreasing …
