Study on photovoltaic stability and performance by incorporating tetrabutyl phosphonium iodide into the active layer of a perovskite type photovoltaic cell

Schematic representation of the solar cell configuration with alkylphosphonium modified perovskite layer.

Design of bifunctional quaternary phosphonium salt catalysts for CO2 fixation reaction with epoxides under mild conditions

An efficient synthesis of cyclic carbonates from epoxides and CO2 under mild reaction conditions was achieved via the use of a designed bifunctional quaternary phosphonium iodide catalyst.

Phosphonium iodide as a donor liquid electrolyte for dyesensitized solar cells

An efficient triphenylmethylphosphonium iodide-based liquid electrolyte was synthesized and used for the first time as an electrolyte in dye-sensitized solar cells (DSSCs). With the as-synthesized electrolyte, the DSSC yielded an overall light to electricity conversion efficiency of 5.34 % to 7.10 %, when the radiant power was tuned from 100 mW cm-2 to 10 mW cm-2. This may be attributed to the limitation of mass transport in the DSSC. The electronic and ionic processes in the DSSC were investigated by electrochemical impedance spectroscopy and linear voltammography, respectively.
