Rheological analyses, such as amplitude sweep studies and tack tests, indicate that gels with good rigidity, strength and adhesiveness were attained upon inclusion of 20 wt% of HEC onwards. However, beyond 60 wt% of HEC, the mechanical properties and ionic conductivity of the gels were considerably compromised. Gels comprising 20�60 wt% of HEC were then fabricated into quasi-solid dye-sensitised solar cells (QSDSSC) with the addition of tetrapropylammonium iodide/iodine. The highest efficiency of 3.02% was recorded with gels comprising 70 wt% of PhSt and 30 wt% of HEC, which to the best of our knowledge is the highest ever efficiency in literature for starch-based electrolytes. Electrochemical impedance spectroscopy (EIS) of the QSDSSC revealed that the adhesive property of the gels plays a crucial role in charge transfer processes at the electrode/electrolyte interfaces. � 2020 International Solar Energy Society Final 2023-05-29T08:11:18Z 2023-05-29T08:11:18Z 2020 Article 10.1016/j.solener.2019.12.074 2-s2.0-85077659192 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85077659192&doi=10.1016%2fj.solener.2019.12.074&partnerID=40&md5=d4b6266072914dd944f2ab07695749f2 https://irepository.uniten.edu.my/handle/123456789/25586 197 144 153 Elsevier Ltd Scopus |
