FAQS about Solar cell electrode function
How do solar cells work?
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
How to choose a solar cell electrode?
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.
How do electrodes work?
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.
Which electrode material is best for inverted hybrid solar cells?
The electrodes made of Al and Ag shows higher output power compared to the device made of Au electrode. These experimental data leads to the conclusion that Ag is the optimal top electrode material for use in inverted devices. Thus, electrodes made of Ag are relatively a better option for the back electrode in inverted hybrid solar cells.
Which metals are used for back-contact electrodes in perovskite solar cells?
Metallic layers of Al, Au, and Ag have been reported to be used regularly for back-contact electrodes in the current advancements in perovskite solar cells. The metals with suitable work function and resistivity have been chosen as electrodes in PSCs.
Operation Principle of Solar Cell
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics –. . 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. . When light photons reach the p-n junctionthrough the thin p-type layer, they supply enough energy to create multiple electron-hole pairs, initiating the conversion process. The. Solar cells convert sunlight directly into electricity. They use semiconductors as light absorbers. When the sunlight is absorbed, the energy of some electrons in the semiconductor increases. [pdf]
