New Guide Available: Green OPV Solvents
Posted on Tue, Aug 14, 2018
Despite continuous improvement in the efficiencies of lab-scale organic solar cells, most devices still use aromatic halogenated solvents to dissolve active layers. Whilst good for making efficient solar cells, solvents of this type are subject to stricter regulation as they often have negative effects on the environment and human health.
This leads to a situation where the advantages of organic photovoltaics (OPVs) - low production cost and low environmental hazards - cannot be fully realised, because they clash with the disadvantages of halogenated solvents.
Fortunately, this can be resolved by using environmentally-benign 'green' solvents - a term used to describe non-halogenated solvents. The environmental accumulation of 'green' solvents is easier to manage, making them preferable for large-scale OPV manufacture.
Our latest guide - "Green Solvents for Organic Photovoltaics" explores the challenges of using 'green' solvents, explains what their use looks like in practice, and what the future might hold for environmentally-benign OPV systems.
