Investigation of Effective Parameters on the Performance of Hot Carrier Solar Cells
Nowadays silicon crystalline solar cell efficiency has reached about 25%. Quantum dot solar cells can considerably increase the cell’s efficiency. The underlying concept of hot carrier solar cells is slowing the rate of photo-excited carrier cooling that is made by phonon interaction in the lattice and allowing much time for the carriers to be collected until they are still at elevated energies. In this condition higher cell voltage can be achieved and also the total efficiency of solar cell has increased. In this paper the affective parameters on the efficiency and performance of the hot carrier solar cell has been investigated. The results show that if the size of quantum dots be 8 times their total energy has reduced 5 times. Also by using quantum dots in cell’s contact the efficiency could be increased to 81%. If the temperature of the hot carriers 25 percent increases, the cell efficiency increases to 60 percent. As well as 100 degree rise up in temperature, is caused efficiency decreases till 2 percent. This results shows that the cell is not sensitive to changes in ambient temperature. According to cell efficiency variation based on band gap, using InN and Ge quantum dots in the cell’s contacts is proposed.
