Abstract
A photoelectrode (12) for use in a photocell (10) comprises a graphene substrate (22) functionalized with carbon quantum dots (CQDs) (20). A photocell (10) comprises a photoelectrode (12), a counter electrode (14), and an electrolyte (26). The electrolyte (26) may be a solid polymer electrolyte. The photocell (10) may be an electrochemical UV sensor. A method for sensing UV radiation comprises quantifying a power density of UV radiation using an electrochemical UV (10) sensor comprising CQDs (20) as a photoactive material. The CQDs (20) may be nitrogen-doped CQDs.
