Abstract:
In this work we present the results we obtained by processing 1 ?*cm p-type alkaline textured multi-crystalline silicon wafers when a double hydrogenated amorphous/crystalline silicon heterojunction is applied to sandwich the substrate. At the sunward surface to form the emitter and at the rear side to act as back surface field. We investigate the efficiency limiting factors by evaluating the photogeneration mechanism and we address a way of improvement. Even if the obtained photovoltaic efficiency is not impressive (15%), it is worth to note that this result is one of the very few results obtained on hydrogenated amorphous/crystalline silicon heterostructure based on p-type textured multi-crystalline silicon wafer, and the best published up to now.
