tailieunhanh - Synthesis of Cu+/bipyridyl based complex towards dye sensitized solar cell applications

This study aims to synthesize the Cu+/bipyridyl-based complex using Sonogashira cross coupling. The structure of the ligand and the complex were investigated by nuclear magnetic resonance spectroscopy; by single crystal X-ray diffraction and by UV-VIS absorption spectroscopy. The obtained experimental results were in good agreement with the theoretical calculations. The complex is a potential candidate to be the photo sensitizer in dye-sensitized solar cells. | Communications in Physics, Vol. 26, No. 2 (2016), pp. 165-171 DOI: SYNTHESIS OF Cu+ /BIPYRIDYL BASED COMPLEX TOWARDS DYE SENSITIZED SOLAR CELL APPLICATIONS VUONG SON1 , NGUYEN NGOC HA2 , LUONG THI THU THUY2 , TRAN QUANG THINH1 AND MAI ANH TUAN1,† 1 International Training Institute for Materials Science (ITIMS), Hanoi University of Science and Technology (HUST) 2 Faculty of Chemistry, Hanoi National University of Education (HNUE) † E-mail: Received 30 May 2016 Accepted for publication 25 July 2016 Abstract.

Solar cell operates according to the photovoltaics effect [1] in which the cell converts directly the solar radiation into a direct current. Three generations of solar cells have been introduced so far in which Si-wafer based cell had a share of around 90% of the total production in 2013 [2]. The first generation, which is Si-wafer based, and the second one, which is amorphous silicon based and copper indium gallium selenide (CIGS) based, are technologically matured and it is hard to reduce the price in fabrication processes. These technologies are also subjected to possible difficulties and environmental impacts after the solar cell life cycle. The liquid-based dye sensitized solar cell that belongs to the third generation was first reported in Ref. [3, 4], and
