Abstract

Abstract : Boron and fluoride co-doped TiO2 nanomaterial is successfully synthetized using a facile process, followed by chemical bath deposition in an organic solution to ensure high wettability and superior penetration ability of the B/F co-doped TiO2 films. Abstract : A highly crystalline mesoporous boron and fluoride (B/F) co-doped TiO2 nanomaterial is successfully synthetized using a facile process, followed by chemical bath deposition (CBD) in an organic solution to prepare the QD-cell to ensure high wettability and superior penetration ability of the B/F co-doped TiO2 films. A modified polysulfide redox couple, ((CH3 )4 N)2 S/((CH3 )4 N)2 S n, was employed in a cadmium sulfide (CdS) quantum dot (QD)-sensitized B/F co-doped TiO2 solar cell covered with ZnS passivation layers with cobalt sulfide (CoS) as a counter electrode; then, an open-circuit photovoltage of 1.223 V, a high FF of 85.9%, a short-circuit photocurrent ( J sc ) of 4.52 mA cm −2, and a high overall energy conversion of 4.74% were obtained.
