| Popis: | As a promising solar energy conversion device, quantum dot (QD) co-sensitized solar cells have been facing a great challenge of improving their efficiencies. To shed light on the possibilities and potential approaches of accomplishing such mission, this article presents an investigation based on the comparison between diverse cells including CdS/CdSe QD co-sensitized and solely sensitized ones, which differ in either anode structures or fabrication methods. We show the photoelectric characteristics and properties of two cells with CdSe@CdS and CdS@CdSe co-sensitization modes, respectively, and discuss the causes that influence the cell efficiencies in each modes. Subsequently, the two co-sensitization modes are compared each other in the aspects of anode structures, fabrication methods and their impacts on the basic battery parameters. By exploring the origins of the variations in basic battery parameters, we attempt to reach an access to reasonable clarification on the factors to cell efficiencies. |
