Effect of CdSMg-Doped CdSe Cosensitized Photoanode on Quantum Dot Solar Cells

Abstract EN

Quantum dots have emerged as a material platform for low-cost high-performance sensitized solar cells.

And doping is an effective method to improve the performance of quantum dot sensitized solar cells (QDSSCs).

Since Kwak et al.

from South Korea proved the incorporation of Mg in the CdSe quantum dots (QDs) in 2007, the Mg-doped CdSe QDs have been thoroughly studied.

Here we report a new attempt on CdS/Mg-doped CdSe quantum dot cosensitized solar cells (QDCSSC).

We analyzed the performance of CdS/Mg-doped CdSe quantum dot cosensitized solar cells via discussing the different doping concentration of Mg and the different SILAR cycles of CdS.

And we studied the mechanism of CdS/Mg-doped CdSe QDs in detail for the reason why the energy conversion efficiency had been promoted.

It is a significant instruction on the development of Mg-doped CdSe quantum dot sensitized solar cells (QDSSCs).
