Promoting charge-separation in p-type dye-sensitized solar cells using bodipy

Abstract

The viability of applying bodipy sensitisers to NiO-based p-type dye-sensitised solar cells (p-DSCs) has been successfully demonstrated. The triphenylamine donor–bodipy acceptor design promotes a long-lived charge-separated state which is difficult to achieve with NiO-based devices. The current was above 3 mA cm⁻² and the IPCE was 28%.
