Photovoltaic Intelligent Gas Sensors Based on Porous Silicon-crystalline Silicon Heterojunction. Technology and Application

The concentration of polar gases in the measuring chamber affects the way of employing photo-electromotive forces on the heterojunction between porous silicon thin layer and crystalline silicon wafer. Electrochemical etching on a p-type silicon wafer produced the porous silicon thin layer. To this porous layer, a gas and light transparent electrical contact was created. Controlling…
