Effect of the electrochemical etching (anodization) that is one of the manufacturing process of porous silicon (PS) on the electrical parameters of metal-porous silicon direct hydrogen cell (Metal-PS-DHC) is considerably high. There is 4 basic anodization parameters of n-type, (111) oriented, single crystal PS fabricated in this study (time, current density, HF ratio and light). 5-100 Min. of anodization time, 5-75 mA/cm2 of current density, 1:1- 1:11 of HF:deionized H2O ratio and 1000-7000 lux light intensity is applied. The best anodization time is 40 minutes and corresponding Metal-PS-DHC electrical cell parameters are Voc= 590 mV and Isc=30 µA. The best HF: H2O ratio is 1:3 and the corresponding Metal-GS-DHP electrical cell parameters are Voc= 540 mV and Isc=18 µA. The best light intensity is 4000 lux and the corresponding MetalGS-DHP electrical cell parameters are Voc= 540 mV and Isc=18 µA. As the experimental results show, Metal-GS-DHP electrical cell parameters are directly related to the anodization conditions. |
