of solar cells. In this study, we synthesized Ag-Zn-Ga-S-Se-based alloyedQDs by colloidal hot injection and characterized them. The X-ray photoelectron spectrum analysis confirms the +1, +2, +3, −2, and −2 oxidation states of, respectively, Ag, Zn, Ga, S, and Se in the QDs, and the energy-dispersive
performance studies. The fabricated QDSC have superior electrochemical activity with a photoconversion efficiency of 4.91%.

Human life depends on various forms of energy. Approximately 13 terawatts of
. Hence, they have application potential in optoelectronic devices.
Herein, we synthesized, for the first time, Ag, Zn, Ga, S, and Se-based alloyedQDs (AZGSSe QDs) and investigated the optoelectric and morphological properties. Due to the near-infrared (NIR) light absorption, the QDs were used as
