ZnO Nanowire Based Dye Sensitized Solar Cells

• We are using ZnO nanowires grown from aqueous
  solution of methenamine and zinc nitrate at Tlt100
  oC as the wide band gap semiconductor in dye
  sensitized solar cells.
• NNIN facilities are used to characterize the ZnO
  nanowires and NFC is used to fabricate the solar
  cell electrode contacts.
