Does zinc oxide enhance photovoltaic properties of PSCs?

To enhance the photovoltaic properties of PSCs, several materials for the electron transport layer (ETL) have been investigated. Zinc oxide (ZnO) is a significant ETL due to its high electron mobility and optical transparency in PSCs. As a result of various deposition methods, ZnO ETL can be processed at low temperatures.

Is zinc oxide an electron transport layer in planar perovskite solar cells?

How is ZnO used in photovoltaic cells?

In photovoltaic field, ZnO has been widely used in different emerging solar cells devices such as perovskite solar cells, kesterite-based devices, quantum dot, dye-sensitized, and organic solar cells [11, 12, 13, 14]. ZnO versatility and variety of synthesis methods allow to have a diversity of roles in this kind of devices for the same material.

Does high temperature annealing reduce interstitials in ZnO thin films?

It was observed that the ZnO thin films annealed at 400 °C exhibited high electrical conductivity and carrier concentration confirming the presence of Zn interstitials. High temperature annealing caused reduction in both of the above parameters which suggested the elimination of Zn interstitials at higher annealing temperature.

What materials are used in emerging photovoltaic technologies?

One of the most used materials in the emerging photovoltaic technologies is the ZnO, which can be used in several emerging devices and which has been widely studied by using different techniques.

How does ZnO layer synthesis affect the performance of inverted OPV devices?

It is also to be noted that the performance of inverted OPVs devices is largely influenced by the method of ZnO layer synthesis and hence the properties of the ZnO layer such as morphology, microstructure, thickness, crystallinity, and the optoelectronic properties.
