Abstract
The remarkable rise in power conversion
efficiency (PCE) of perovskite solar cells (PSCs), now exceeding 26%, has
positioned them as front-runners in next-generation photovoltaic technologies.
However, persistent challenges related to long-term operational stability,
interfacial degradation, and charge carrier recombination hinder their
large-scale commercialization. In this context, graphene and its
derivatives—including graphene oxide (GO), reduced graphene oxide (rGO), and
functionalized graphene nanostructures—have emerged as promising materials to
enhance PSC performance and durability. This review systematically analyzes
recent advances in integrating graphene-based materials into perovskite solar
cells. It begins with an overview of perovskite materials and device
architectures, followed by a detailed examination of the optoelectronic
properties of graphene. The core of the article discusses how graphene enhances
different layers in PSCs—electron transport layers (ETL), hole transport layers
(HTL), electrodes, and interfacial layers—through improvements in conductivity,
stability, and carrier mobility. Emphasis is placed on synthesis methods,
doping strategies, and device engineering approaches that utilize graphene
composites, nanoribbons, and hybrids with quantum dots or conjugated polymers.
The article also highlights challenges such as interfacial incompatibility,
environmental instability, and synthesis scalability. It concludes with future
research directions including flexible graphene-based PSCs, environmentally
benign materials, and industrial-scale fabrication. This review serves as a
guide for materials scientists, chemists, and engineers aiming to design
robust, high-efficiency perovskite solar devices empowered by graphene
innovations.
