AbstractMetal doping can effectively enhance the photovoltaic performance of quantum dot (QD) sensitized solar cells (QDSSCs). In this study, we investigated the effect of a Mg-doped CdS (Mg-CdS) QD post-deposition layer on the optoelectronic properties of CuInSe2 (CISe) QDSSCs, which were synthesized by a low-temperature hot injection method. The ex-situ peptization technique was adopted for sensitization of CISe QDs, followed by cosensitization of Mg-CdS through a successive ionic layer adsorption and reaction method. The fabricated TiO2/CISe/Mg-CdS sensitized solar cell displayed excellent photovoltaic performance with a power conversion efficiency of 4.65% (Jsc = 17.43 mA/cm2, Voc = 0.66 V) under AM 1.5 G one full-sun illumination. Furthermore, the Mg-CdS layer passivated the surface of the CISe QD solar cell, which reduced current leakage at the surface of the CISe QDs. Moreover, the Mg-CdS passivation improved stability of the solar cell.
