Photocatalytic Oxidation of Triiodide in UVA-Exposed Dye-Sensitized Solar Cells

open access: yesInternational Journal of Photoenergy, 2012
UVA irradiation of glass mounted dye-sensitized solar cells without UV filtration causes failure within 400 hours of light exposure. The failure mode is shown to relate to consumption of I3−, which is directly related to TiO2 photo-catalysis.

Novel Voltage Control Method of the Primary Feeder by the Energy Storage System and Step Voltage Regulator

open access: yesEnergies, 2019
With the intention of keep the customer voltage within a nominal voltage boundary (the South Korea voltage regulation in range of 220 V ± 6% for a single phase), the SVR (step voltage regulator) method in the primary feeder has been seriously ...

UV Filtering of Dye-Sensitized Solar Cells: The Effects of Varying the UV Cut-Off upon Cell Performance and Incident Photon-to-Electron Conversion Efficiency

open access: yesInternational Journal of Photoenergy, 2012
With current technology, UV filters are essential to ensure long-term dye-sensitized solar cell (DSC) stability. Blocking photons, however, will have an obvious effect on device performance and upon its incident photon-to-current conversion efficiency ...

Synthesis and electrochemical Li-storage performance of Li2ZrO3-Li3V2(PO4)3/C composites

open access: yesElectrochemistry Communications, 2021
A simple and efficient synthetic route was developed to obtain composites by mechanically ball-milling Li2ZrO3 (LZO) with Li3V2(PO4)3/C (LVPC). LZO improves the ionic conductivity of LVPC, compensates for the transfer of Li+ between the LVPC and the ...
