Major scientific contributions

Brian O'Regan is known for his pioneering work on the deposition of meso-porous oxides from colloidal solutions that ultimately led to the first high efficiency DSSC. He has also developed the first high efficiency non-aqueous electrolyte for DSSC and more recently has overturned the belief that water is poisonous to dye sensitisation by designing water based and water tolerant DSSC. He has invented TiO₂ electrodeposition from TiCl₃, electrodeposition of CuSCB and non-aqueous electrodeposition of aligned mesoporous ZnO. He holds 5 patents and is the author of numerous research papers.
