“…146 Similar reports detail an isopropanol ultrasonically-treated graphene-based encapsulant enhancing the stability of a PSC by 90% within 60 h by reducing oxygen oxidation and moisture attack. 164 In addition, the high thermal conductivity of graphene helps with thermal stress on PSCs, leading to additional stability benefits. 95,109 A graphene derivative–carbon paste has been reported as a suitable encapsulant of PSC modules of areas 0.09, 1 and 4 cm 2 that achieved champion PCEs of 15.81%, 14.06% and 13.86%, respectively.…”

“…The bond between the shielding molecules and perovskite molecules is insufficient to protect the material from water and oxygen for a lengthy period of time. Inorganic materials have a large bandgap that can reduce the surface recombination speed and change the surface work function energy level for a better match [ 118 , 119 , 120 , 121 ]. They are chemically stable in humid air and can be used as a passivation material for lead–halide perovskites.…”

Perovskite solar cells (PSCs) are the most promising substitute for silicon-based solar cells. However, their power conversion efficiency and stability must be improved. The recombination probability of the photogenerated carriers at each interface in a PSC is much greater than that of the bulk phase. The interface of a perovskite polycrystalline film is considered to be a defect-rich area, which is the main factor limiting the efficiency of a PSC. This review introduces and summarizes practical interface engineering techniques for improving the efficiency and stability of organic–inorganic lead halide PSCs. First, the effect of defects at the interface of the PSCs, the energy level alignment, and the chemical reactions on the efficiency of a PSC are summarized. Subsequently, the latest developments pertaining to a modification of the perovskite layers with different materials are discussed. Finally, the prospect of achieving an efficient PSC with long-term stability through the use of interface engineering is presented.

“…In addition to their utilization as electrode materials in energy storage devices, graphene is also applicable for energy conversion as well as energy generation purposes. ,,, In devices like fuel cells (FCs) and dye-sensitized solar cells (DSSCs), graphene plays an important role in the efficient conversion of chemical/solar energies into electrical energy. In FCs, graphene derivatives were suitably applied for decreasing the loading of Pt-based catalysts, as a catalyst support/standalone catalyst, or as an electrolyte membrane with the similar performances to that of other materials. − In the case of dye-synthesized solar cells, graphene derivatives were found to be improving the efficiency as well as stability of DSSCs by employment at the photoanode, electrolyte, and the counter electrode. − As these energy converting/harvesting devices utilize the expensive and limited Pt-based catalysts, the use of graphene derivatives as an alternative as well as supportive material not only reduces the cost but also acts as a viable replacement with accepted performance and stability.…”

In the last decade, there has been a phenomenal development in the commercially viable, large-scale synthesis of graphene, a multifunctional advanced carbon nanomaterial, which is gaining popularity for its diverse range of applications, especially in energy storage, composites, sensors, and membranes. With the increasing demand, a large number of worldwide research efforts have been employed, resulting in a series of enormous breakthroughs both in its fundamental science and innovative applications. The earlier reviews on graphene show that the increase in the production yield is often accompanied by the generation of substandard graphene quality, making the process unsuited for commercialization. However, recent studies on graphene synthesis have shown the use of naturally available carbonaceous sources for the production of low-cost graphene derivatives is becoming an emerging trend in graphene research. In this present review, the most recent advances in the synthesis of high-quality graphene from solid carbon precursors, particularly abundant coal, biomass, and waste materials, have been extensively discussed along with their potential scalability for commercial production. The quality and yield of these graphene derivatives synthesized through different methods like chemical vapor deposition, exfoliation, laser-induced, microwave irradiation, and chemical methods are also examined to determine the best-suited synthetic methodology from the available literature. The utilization of graphene derivatives in the energy sector was further discussed, particularly in the emerging field of energy storage. Finally, the challenges and future prospects of this study are highlighted to have a better understanding of the current graphene production scenario, with an insight into the most efficient method for synthesizing high-purity low-cost graphene and their potential for scaleup and energy applications in the distant future.
