X-ray photoelectron spectroscopy and auger electron spectroscopy studies of Al-doped ZnO films
TLDR
In this article, the chemical state of oxygen, aluminum and zinc in Al-doped ZnO (ZAO) films was investigated by X-ray photoelectron spectroscopy (XPS), as well as the transition zone of the film-to-substrate, by auger electron spectrography (AES), showing that zinc remains mostly in the formal valence states of Zn2+.About:

Inverted Polymer Solar Cells Integrated with a Low‐Temperature‐Annealed Sol‐Gel‐Derived ZnO Film as an Electron Transport Layer
TL;DR: BHJ solar cells are typically fabricated with a transparent conductive anode, a low-work-function metal cathode, and an active layer sandwiched between the anode and cathode.

Oxygen vacancy induced band-gap narrowing and enhanced visible light photocatalytic activity of ZnO.
Junpeng Wang,Zeyan Wang,Baibiao Huang,Yandong Ma,Yuanyuan Liu,Xiaoyan Qin,Xiaoyang Zhang,Ying Dai +7 more
TL;DR: The ZnO with oxygen vacancies are found to be efficient for photodecomposition of 2,4-dichlorophenol under visible light irradiation and a narrowing bandgap can be confirmed by the enhancement of the photocurrent response when theZnO was irradiated with visible light.

Oxygen Vacancy Enhanced Photocatalytic Activity of Pervoskite SrTiO3
Huaqiao Tan,Zhao Zhao,Wanbin Zhu,Eric N. Coker,Binsong Li,Min Zheng,Weixing Yu,Hongyou Fan,Hongyou Fan,Zaicheng Sun +9 more
TL;DR: UV-vis spectra and photocatalytic results indicate that oxygen vacancies on STO surface play an important role in influencing the light absorption and photoc atalytic performance, however, an excess amount of oxygen vacancies leads to a decrease of photocatallytic performance.

Oxygen vacancy induced band gap narrowing of ZnO nanostructures by an electrochemically active biofilm
Sajid Ali Ansari,Mohammad Mansoob Khan,Shafeer Kalathil,Ambreen Nisar,Jintae Lee,Moo Hwan Cho +5 more
TL;DR: A simple biogenic approach for the promotion of oxygen vacancies in pure zinc oxide (p-ZnO) nanostructures using an electrochemically active biofilm (EAB), which is different from traditional techniques for narrowing the band gap of nanomaterials, resulted in band gap narrowing of the ZnO nanostructure.
