In an analytical study, researchers from Sharif University of Technology in association with researchers from the Spanish Universitat Jaume and the Japanese University of Tokyo studied the amount of voltage in solar cells sensitized with quantum dots and succeeded in introducing methods to increase efficiency of the cells.
In the field of solar cells sensitized with quantum dots, the majority of the researchers have so far followed the previous researches carried out on solar cells sensitized with pigments. The reason is the similarity between these two types of cells.
According to Dr. Mahmoud Samadpour, one of the researchers of the project, this analytical research shows that there are fundamental differences between these two types of cells, and a new approach has been presented in order to increase the efficiency of solar cells sensitized with quantum dots.
Dr. Samadpour said that the team could successfully solve a part of the problem in voltage drop in solar cells sensitized with quantum dots by using the result of this research.
In addition, the research presents a new method to increase the efficiency of solar cells sensitized with quantum dots as well as a solution to increase the voltage.
Nanotechnology plays an important role in the research, and according to Dr. Samadpour, using nanotechnology leads to an increase in the efficiency of the solar cells. Due to the presence of the nanometric structures used in the cell anode, the effective area of the cell increases significantly.
