Electrochemiluminescence (ECL) is a phenomenon of luminescence that is initiated by a step of transferring electrons to the surface of an electrode. On the other hand, photoelectrochemistry on semiconductors (SCs) is an antagonistic phenomenon converting light absorption into electrochemical current. The aim of this thesis is to explore potential technologies coupling ECL and photoelectrochemistry on SC. This will involve preparing and characterizing SCs photoelectrodes and studying their behavior in a solution containing an emissive molecule allowing the generation of ECL.
