MOS solar cells with oxides deposited by sol-gel spin-coating techniques

The metal-oxide-semiconductor (MOS) solar cells with sol-gel derived silicon dioxides (SiO2) deposited by spin coating are proposed in this study. The sol-gel derived SiO2 layer is prepared at low temperature of 450°C. Such processes are simple and low-cost. These techniques are, therefore, useful for largescale and large-amount manufacturing in MOS solar cells. It is observed that the short-circuit current (Isc) of 2.48 mA, the open-circuit voltage (Vos) of 0.44 V, the fill factor (FF) of 0.46 and the conversion efficiency (η%) of 2.01% were obtained by means of the current-voltage (I–V) measurements under AM 1.5 (100 mW/cm2) irradiance at 25°C in the MOS solar cell with sol-gel derived SiO2.
