摘要

Dye sensitized solar cells (DSSCs) were fabricated using anthocyanin dye and polymer electrolyte with ammonium iodide (NH_(4)I) salt. The study was designed to focus on increasing the efficiency of the DSSC. DSSC using 26.9 wt. percent chitosan-22 wt. percent NH_(4)I(+2.2 wt.percent I_(2))-48.9wt. percent IL solid electrolyte, black rice anthocyanin with Pt counter electrode showed J_(sc) of 172 (mu)A cm~(-2) and V_(oc) of 195 mV. The performance of the cell with Pt electrode was further improved by coating a blocking layer on the indium tin oxide (ITO) substrate. The black rice DSSC using 11 wt. percent (chitosan:PEO, wt. ratio 30:70)-9wt. percent NH_(4)I-80wt. percent BMII gel electrolyte exhibited J_(sc) of 1213 (mu)A cm~(-2), Voc of 400 mV, FF of 0.47, and eta of 0.23percent. The red cabbage anthocyanin DSSC containing (phthaloyl chitosan-PEO)-NH_(4)I-BMII gel electrolyte using tartaric acid to adjust the pH of anthocyanin solution showed the best performance with the fill factor of 0.39, J_(sc) of 3503 (mu)A cm~(-2), V_(oc) of 340 mV, and an overall conversion efficiency of 0.46percent.
