6 FAQs about [Electrode reactions of solar cells]
Are electrodes used in perovskite 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.
Does silver alloy electrode deteriorate on crystalline silicon solar cells?
In this paper, the deteriorated silver alloy electrode on crystalline silicon solar cells was analyzed using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS).
Which electrode is used in dye-sensitized solar cells?
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).
Why do solar cells fail early?
However, along with the introducing minor elements in the silver paste, the early discoloration of silver electrode appears on solar cells within a short time. Such a deterioration would lead to the poor solderability of silver electrode during modules encapsulation, thereby causing the early failure of solar modules.
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.
Does silver paste deteriorate a silver alloy electrode on solar cells?
Therefore, the higher the content of Bi in the silver paste is, the faster the deterioration of silver alloy electrode on solar cells. The results of the peel test show that the solderability of the deteriorated electrode becomes poor, which causes a significant decrease in the peel force of ribbon.
