Brian O'Regan (chemist)

Brian C. O'Regan is an American chemist known for the co-invention of dye-sensitized solar cells (DSSC, DSC, SSC). He was previously a Research Lecturer at Imperial College London where he conducts research on photovoltaic cells and other applications of nano-structured oxide electronic materials.

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.[1] 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.[2] 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.
