The quantum dots were synthesized on a nanoporous TiO2 electrode. To improve efficiency, passivation treatments including a TiO2 under layer and additional treatments including annealing and an Au counter-electrode were used. The crystallinity and morphology were characterized by X-ray diffraction and transmission electron microscopy. The optical properties of the AgBiS2 quantum dots were characterized by UV-vis spectroscopy. Polysulfide was used as the electrolyte. The best cell yields a short-circuit current of 7.61 mA/cm2, an open circuit voltage of 0.18V, a fill factor of 38.6% and a power conversion efficiency of 0.529 % at one sun.
