Quantum wire solar cell

In this work a new solar cell design, where a vertical array of nanometric wires (or vertical closely coupled dots) is inserted between the p and n conductivity regions of conventional solar cell is proposed. The proposed approach is shown to enhance the photo-absorption of the solar cell toward the infra-red, and, owing to an efficient 1 D-electron gas-assisted carrier collection, to improve significantly current output and efficiency of single junction solar cells.
