This paper presents the optical hydrogen sensor based on transparent 3C-SiC membrane and photovoltaic effect. Gasochromic materials of Pd and Pd/WO3 were deposited by sputter on 3C-SiC membrane for gas sensing area. Gasochromic materials change to transparency by exposure to hydrogen. The variations of light intensity by hydrogen generate the photovoltaic of P-N junction between N-type 3C-SiC and P-type Si. Single layer of Pd shows higher photovoltaic compared with Pd/WO3. However, phase transition from to is shown at 6 %. Pd/WO3 structure show the more linear response to hydrogen range of 2 % 10 %. Also, almost 2 times fast response and recovery characteristics are shown at Pd/WO3. These fast performances are come from the fact that Pd promoted the chemical reaction between hydrogen and WO3.
