Research question
Despite achieving record power conversion efficiencies (PCEs) exceeding 18% and device lifetimes ranging from months to years, OPV has not yet gained commercial success on a large scale. The use of inorganic zinc oxides (ZnO) in OPVs has drawbacks, including UV activation that damages organic layers and poor interface properties, leading to reduced performance and shorter module lifetimes. OPV technology offers lower production costs due to roll-to-roll printing at room temperature. However, the challenge lies in developing water-based n-type inks with high conductivity, processability, and stability, equivalent to conventional hole transporting layer materials, which would have a significant impact on OPV manufacturing.
Sustainability aspects
We aim to use the innovative idea of water-soluble n-type conductive polymers to create a material that serves as both an electron transport layer (ETL) and a low-work function electrode. This novel class of material is expected to enhance both power conversion efficiency (PCE) and longevity while simplifying OPV-stack construction through the use of environmentally friendly and sustainable inks.
