摘要

Abstract

BSTRACTWe herein provide a strategy to improve the solar cell performance by merging upconverting nanophosphors (UCNPs)

tri-doped NaYF

into TiO

photoanodes of quantum dot-sensitized solar cell (QDSSCs). The best performance was achieved at the UCNPs content of 8 wt% based on the systematic investigation of the power conversion efficiency (PCE) performance dependent on UCNPs amount. The short-circuit photocurrent (

) (21.30 mA cm

−2

) and open circuit photovoltage (

) (0.54 V) of QDSSC were obviously improved compared with those of pure TiO

photoanode (

of 14.67 mA cm

−2

of 0.48 V) under one sun illumination

resulting in a 42.6% enhancement in PCE.

Impact statement

The short-circuit photocurrent (

) (21.30 mA cm

−2

) and open circuit photovoltage (

) (0.54 V) of QDSSC using the upconverting nanophosphors incorporated TiO

photoelectrodes were remarkably improved under o

ne sun illumination

resulting in a 42.6% enhancement in power conversion efficiency.
