Quantum-dot-sensitized solar cells (QDSSC) are an alternative solution to addressing some of these issues, in addition to reducing the costs of producing electrical energy. However, QDSSCs present stability problems and low efficiency, less than 16%. In light of this challenge, this review aims to present the main strategies adopted to reduce energy losses
Carbon-based electrodes have been widely applied in perovskite solar cells (PSCs) because of their chemical inertness and compatibility with up-scalable techniques, signifying their solid potential for mass-production. The material scarcity and complexity of metal ore extraction further highlights that conve
A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes.A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor.We then apply a few finer electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.

In competition with the common spin, the electrodeposition (ED) method has emerged as a cost-effective, scalable, and environmentally friendly alternative for perovskite deposition. This article combines an up-to-date critical review with experimental results for the development of perovskite photovoltaics.
Effects such as diffusion of elements from the electrodes to the internal layers, obstruction to moisture and oxygen, proper adhesion, and resistance to corrosion should also be taken under consideration. The choice of the electrodes also depends on the ETL or HTL materials used in the solar cells.
This review aims to summarize the significant research work carried out in recent years and provide an extensive overview of the electrodes used till date in perovskite solar cells. We present a critical survey of the recent progress on the aspect of electrodes to be used in perovskite solar cells.
Though the key work of the electrodes is to collect and transport holes from the HTL or electrons from the ETL, various other properties are equally important and should be studied to choose an appropriate electrode for the device architecture.
The enhancement in current density has resulted in an enhanced initial PCE of 9.9% when compared between the flat electrode-based solar cells and the solar cells based on the nanophotonic front electrode (9.6) (Fig. 7), respectively.
The photovoltaic action of a solar cell occurs as photo-generated carriers, electrons and holes, are generated in (or flow into) a central region of strong electric field, that sends carriers of opposite charge in opposite directions.
The traditional transparent electrode in dye-sensitized cells has been indium tin oxide ITO (or related FTO fluorine tin oxide), on which the anatase layer is deposited, followed by the dye. Graphene transparent electrodes (chemically exfoliated) were applied to dye-sensitized solar cells by Wang et al. (2008) and by Eda et al. (2008).
