Oxygen doping of P3HT:PCBM blends: Influence on trap states, charge carrier mobility and solar cell performance

, 2010
We investigated the influence of oxygen on the performance of P3HT:PCBM (poly(3-hexylthiophene):[6,6]-phenyl C61 butyric acid methyl ester) solar cells by current--voltage, thermally stimulated current (TSC) and charge extraction by linearly increasing ...

Mathematical Modeling and Mechanism of VUV Photodegradation of H2S in the Absence of O2

International Journal of Photoenergy, 2018
The existence of H2S has limited the biogas energy promotion. The traditional photodegradation of H2S is usually conducted in the presence of O2, yet this is unsuitable for biogas desulfurization which should be avoided.

Synthesis of titanate nanostructures using amorphous precursor material and their adsorption/photocatalytic properties

, 2012
This paper reports on a new and swift hydrothermal chemical route to prepare titanate nanostructures (TNS) avoiding the use of crystalline TiO2 as starting material. The synthesis approach uses a commercial solution of TiCl3 as titanium source to prepare

Mechanism of the Photodegradation of A-D-A Acceptors for Organic Photovoltaics.

Angewandte Chemie, 2021
In this work, we elucidate the photodegradation pathway of A-D-A type nonfullerene acceptors for organic photovoltaics. Using IT-4F as a benchmark example, we isolated the photoproducts and proved them isomers of IT-4F formed via a 6-e electrocyclic ...
