TAILIEUCHUNG - Effect of UV filtering on dye-sensitised solar cells

This work aimed to investigate the effect of commercial UV filter films (PS65, SEC04) on the performance and long-term outdoor stability of dye-sensitised solar cells (DSCs). The application of UV filter films to the DSCs lead to a slight decrease in cell performance. However, the cell performance remained constant after 2,000 h of outdoor exposure. Electrochemical impedance analysis showed a small transfer resistance in the TiO2 photo-anode, which corresponded to the low recombination process of the electrons in TiO2 . The low electron recombination process supports the stable performance of the DSCs with the SEC04 film under outdoor conditions. | PHYSICAL SCIENCES CHEMISTRY Doi 1 .38-42 Effect of UV filtering on dye-sensitised solar cells Thai Hoang Nguyen1 2 Le Thanh Nguyen Huynh1 2 Thi Phuong Linh Tran1 Viet Hai Le1 University of Science Vietnam National University Ho Chi Minh city Applied Physical Chemistry Laboratory Vietnam National University Ho Chi Minh city Received 3 July 2019 accepted 15 November 2019 Abstract This work aimed to investigate the effect of commercial UV filter films PS65 SEC04 on the performance and long-term outdoor stability of dye-sensitised solar cells DSCs .

Classification number Introduction During the past half-century the excessive consumption of fossil energy together with the uneven distribution of fossil energy resources in the world has pushed humanity to face serious environmental problems such as the greenhouse effect and lack of renewable energy resources. To overcome these problems the development of clean and renewable energy sources must be a mandatory requirement at present and in the future. Among existing renewable energy sources solar energy is considered to be the cleanest and safest choice. Solar cells are considered to be the most convenient method to turn solar energy into electricity and may even be an alternative to other energy sources since the invention of single-crystal solar cells in 1954. However the issue of high cost is the biggest .
