Graphitic carbon nitride as a photovoltaic booster in quantum dot sensitized solar cells: a synergistic approach for enhanced charge separation and injection

Abstract

A binary hybrid composite of g-C3N4 and ZnO is introduced as a photoanodic material in QDSSC devices and ∼70% improvement in power conversion efficiency is achieved.

Quantum dot sensitized solar cell: Recent advances and future perspectives in photoanode

“…In a very interesting study, graphitic carbon nitride (g-C 3 N 4 ) sheets are used as photovoltaic booster in CdS QDSSC [151]. g-C 3 N 4 has optical band gap of $ 2.77 eV.…”

Graphitic Carbon Nitride Film: An Emerging Star for Catalytic and Optoelectronic Applications

“…Chetia et al. report that a g‐CN nanosheet can serve as a barrier to prevent the reverse tunneling of electrons at the interface; charge injecting from g‐CN to ZnO enhances the conversion efficiency and decreases charge recombination …”
