- W4295800757 abstract "This work presents a novel route for utilizing waste from power plants to create a new power source (solar cells). Bottom ash (BA) ceramic micro-particles were studied to improve an electrocatalytic activity in solar cell applications for the first time. In the counter electrodes (CE) of dye-sensitized solar cells (DSSC), bottom ash was mixed with PEDOT:PSS (PP) and polyvinylpyrrolidone (PVP) (BA/PP/PVP) in volume ratios of 3:7, 4:6, 5:5, and 6:4. We found that bottom ash has a significant impact in improving the electrocatalytic activity and DSSC efficiency of these cells. Moreover, the PP and PVP ratios have a high impact on solar cell performance. The BA/PP/PVP-(6:4) counter electrode attained a higher DSSC efficiency, 2.70%, compared to the other electrodes prepared under similar conditions and a Pt CE based DSSC (3.23%) at AM 1.5 (100 mWcm −2 ). The influences of bottom ash and PP/PVP ratios on film structure, electrocatalytic activity in <?CDATA ${{rm{I}}}_{3}^{-}$?> <mml:math xmlns:mml=http://www.w3.org/1998/Math/MathML overflow=scroll> <mml:msubsup> <mml:mrow> <mml:mi mathvariant=normal>I</mml:mi> </mml:mrow> <mml:mrow> <mml:mn>3</mml:mn> </mml:mrow> <mml:mrow> <mml:mo>−</mml:mo> </mml:mrow> </mml:msubsup> </mml:math> reduction, redox reaction rate, and electron transport were characterized using SEM, CV, Tafel, and EIS, respectively. The results show that low-cost BA/PP/PVP-(6:4) CE is a promising new alternative to Pt CEs in DSSCs." @default.
