Aluminum doped zinc oxide (AZO) thin film, generally used as TCO in solar cells, has been grown onto n-type porous silicon (PS) substrate by rf-magnetron sputtering at room temperature using aluminum (3at%) doped nanocrystalline powder synthesized by the sol–gel method. The obtained AZO film with a thickness of about 0.4μm was polycrystalline with an hexagonal wurtzite structure and preferentially...
