Research project on making organic solar cells inspected

01/07/2011

On April 8th, the research project to make organic solar cells by Prof. Dr. Nguyen Duc Nghia was inspected at the Institute of Chemistry under Vietnam Academy of Science and Technology. This two-year project was carried out by the Institute of Chemistry in two years to conduct scientific and technological research into making dye-sensitized solar cells (DSSC) with the productivity of solar energy transformation of 2% to 5%.

After two years of implementing the project, scientists from the Institute were successful in the initial pilot of making DSSC by biological simulation using Chlorophyll in bindweed leaves as a dye sensitive susbtance, to make DSSC whose energy transform productivity is good and life span is long.

Researchers also conducted the research on making a semiconductor electrode with TiO2 nano particles, which can receive and transmit electrons well. Especially, for the first time, DSSC production technology reused Titanium Dioxide pellicle and quantum dots (TiO2/Qd), to improve the productivity of transforming solar energy from 3.57 to 4.36 and an increase of fill factor from 58.3 to 61.8.

The project initially researched and used solid electrolyte in Gelpolymer form instead of liquid electrolyte, and synthesized Ruthenium (II) bipyrin containing cacbozol group to make DSSC, which can absorb wide light in the region having a wavelength of under 900nm. This dye was used to make DSSC with a transformation productivity of 6.1%.

Member of the Council for Project Inspection, Assoc. Prof. Dr. Pham Van Hoi from the Institute of Material Sciences, said that the project by Mr. Nghia was adequate, obtained research demands and had scientific significance.

According to Assoc. Prof. Pham Huu Ly, from the Institute of Chemistry, the project achieved objectives in science and technology, created young scientists with high qualifications and established a cooperative relationship with researchers from Republic of Korea, Japan and Australia.

Prof. Academician. Nguyen Van Hieu, president of the Council for Project Inspection made a speech

This was an essential research project in the situation of present scientific and technological development, said Prof. Academician. Nguyen Van Hieu, president of the Council for Project Inspection. He was glad to know that Vietnam had undertaken such a practical research. He hoped that young people would make an effort in their study and research to conduct useful projects, contributing to the development of science and technology of the State.
