Abstract:The CdS layer was essential for CdSe quantum dot-sensitized solar cells (QDSSCs) as the seed layer and energy barrier. Here, a novel sol-gel method was employed to prepare the CdS interlayer (SG-CdS) for TiO2 nanorod-based QDSSCs. Due to the sufficient reaction of the Cd and S sources in the sol-gel solution, SG-CdS exhibited fewer impurities than CdS produced by commonly used chemical bath deposition (CBD-CdS). QDSSCs with SG-CdS exhibited an open-circuit voltage of 490 mV, a short-circuit current density of … Show more
