Changes in Optimal Ternary Additive Loading when Processing Large Area Organic Photovoltaics by Spin‐ versus Blade‐Coating Methods

Abstract

Solution-Processed Photovoltaics In article number 2100432, Salima Alem, Benoît H. Lessard, and co-workers observed that optimal device performances are dependent on changing the optimal concentration of the ternary additive in the active layer of the OPV when moving from spin-coating on glass to large area blade-coating on flexible substrates. Silicon phthalocyanines are promising ternary additives in OPV devices but their loading must be tuned as the process is scaled up.
