SOLAR CELL WITH CURRENT BLOCKING LAYER

摘要

A solar cell includes an active layer, a blocking layer and a contact layer. The blocking layer is disposed between a portion of the top surface of the active layer and the bottom surface of the contact layer. The blocking layer serves to reduce current flow between the contact layer and the portion of the active layer covered by the blocking layer. Current flow to the contact layer may occur via gridlines electrically connecting the active layer to the contact layer.
