In this work, buffer layers with various conditions are inserted at an n/i interface in hydrogenated amorphous silicon semitransparent solar cells. It is observed that the performance of a cell strongly depends on arrangement and thickness layer. When arranging bandgaps ascending order from intrinsic layer to n layer, relatively high open circuit voltage short current observed. addition, fill factors improved, owing enhanced shunt resistance under every instance introduced layers. Among during layers, reverse V shape energy bandgap found be most effective for efficiency, which also exhibits intermediate transmittance among all samples. This inspiring result, enabling independent control conversion efficiency transmittance.
