A seminar entitled Fabrication and characterization silicon nano wires heterojunction for Photonic Devices hold at the College of Science, Department of physics. The presenter( Hanaa Hashim inaya) aim the study is to Structural, morphological and optical properties of prepared SiNWs are investigated silicon nanowire arrays are prepared by metal-assisted chemical etching (MACE) method using an Ag as a catalyst and different etching time and application forthe solar cells , photosensor heterojunction and using SiNWs as working electrode in the Photoelectrochemical
