Abstract: Advantages of both inorganic and organic solar cells were brought together in a hybrid solar cell. Recent developments were carried out on these devices to improve their efficiencies. However, several factors limit the performance of hybrid solar cells and one such factor is the inorganic/organic interface. This study reports the deposition of cadmium selenide (CdSe) using successive ionic layer adsorption and reaction (SILAR) process and its application in solar cells for future studies of the interface. CdSe/poly(3-hexylthiophene) (P3HT) solid-state hybrid devices were fabricated. The SILAR process of CdSe was optimized to obtain a uniform film before the fabrication of devices was carried out. Bilayer devices and solid-state quantum dot-sensitized solar cells (QDSCs) were fabricated with CdSe layer deposited using SILAR process on a transparent electrode. A bilayer device consisting of CdSe and P3HT showed a photovoltaic effect with current density (Jsc) of 0.05mA/cm2, open-circuit voltage (Voc) of 0.34V and fill factor (FF) of 0.32, which resulted in a PCE of 0.006%.
