Description |
The present study focuses on enhancing the efficiency of bifacial and back-illuminated dye-sensitized
solar cells (DSCs) by incorporating SiO2 mesoporous layer on TiO2 electrode. The performance of DSCs is
investigated by UVevisible spectroscopy, incident photon conversion efficiency (IPCE) and electrochemical
impedance spectroscopy (EIS). It is observed that the current ratio of back- to front-DSC increases
with the increase in the thickness of SiO2 layer, which in turn influences the incident light to
dyed-TiO2 electrode, especially in the wavelength of 400e600 nm. The Ti foil based flexible small
(0.28 cm2) and sub-module (5 cm � 10 cm) DSCs having this modification show high conversion efficiencies
of 6.76 and 5.54% respectively under 100 mW cm�2 (AM 1.5).
