Three Mistakes We Have Made During Fabrication of Quantum Dots Solar Cell; How Can You Learn From Them

Solar cells are in focus for decades due to their capability to convert solar energy into electrical energy. Quantum dots sensitized solar cell (QDSC) gained much consideration due to their relatively simpler device structure and similarity to dye sensitized solar cell (DSSC). QDs are capable of del...
