Performance of amorphous and microcrystalline silicon pin solar cells under variable light intensity (original) (raw)

This study investigates the performance of amorphous and microcrystalline silicon pin solar cells under varying light intensities. It emphasizes how the fill factor (FF)—a critical parameter for efficiency—behaves differently in these solar cells, especially as a function of short-circuit current density (Jsc). The findings reveal that while Jsc and open-circuit voltage (Voc) increase with light intensity, the FF of amorphous silicon cells decreases, contrasting with microcrystalline silicon cells where FF increases up to an optimal point under similar conditions. A simulation model, ASDMP, is utilized to provide deeper insights into the operational differences between these cell types.
