Investigators from School of Applied Sciences Have Reported New Data on Quantum Dots (Doped Heterojunction Used in Quantum Dot Sensitized Solar Cell)

July 25, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Data detailed on Quantum Dots have been presented. According to news reporting out of Beijing, People's Republic of China, by VerticalNews editors, research stated, "Incorporated foreign atoms into the quantum dots (QDs) used in heterojunction have always been a challenge for solar energy conversion. A foreign atom indium atom was incorporated into PbS/CdS QDs to prepare In-PbS/In-CdS heterojunction by successive ionic layer adsorption and reaction method which is a chemical method."

Our news journalists obtained a quote from the research from the School of Applied Sciences, "Experimental results indicate that PbS or CdS has been doped with In by SILAR method; the concentration of PbS and CdS which was doped In atoms has no significantly increase or decrease. In addition, incorporating of Indium atoms has resulted in the lattice distortions or changes of PbS or CdS and improved the light harvest of heterojunction."

According to the news editors, the research concluded: "Using this heterojunction, Pt counter electrode and polysulfide electrolyte, to fabricate quantum dot sensitized solar cells, the short circuit current density ballooned to 27.01 mA/cm(2) from 13.61 mA/cm(2) and the open circuit voltage was improved to 0.43V from 0.37V at the same time."
