Efficiency Enhancement of Dye Sensitized Solar Cells with a Low Cost Co-Adsorbant in N719 Dye

Abstract

Sunlight is a limitless form of renewable and clean energy which is amply accessible. Economic consumption of solar energy can boundlessly fulfil the energy demand. Dye-sensitized solar cells (DSSCs) are acknowledged as third generation solar cell technology because of their environmental friendliness, cost effectiveness, simple fabrication and capability to be manufactured on huge substrates. The prospective for development of various Dye sensitized solar cell components is massive. We have under taken a series of investigations on the photovoltaic performance enhancement of DSSCs. In this work, effect of chenodeoxycholic acid (CDCA) in N719 dye solution as a co-adsorbent and low cost additive was investigated. The cells were fabricated with and without the addition of CDCA. The co-adsorbent significantly improved the photovoltage open circuit (Voc), photocurrent density (Jsc) and the solar energy power conversion efficiency (). The impedance spectroscopy is also discussed in the paper.
