Abstract

Porous CdSe photoelectrochemical converter is fabricated and tested using highly porous substrate of metallic Cd. Following mean PEC characteristics obtained: efficiency: 5%. On the other hand,  CdSe  semiconductor  developed  on  the  highly  porous  (60%) cadmium  substrate  showed  some 2%  of  efficiency  with  high  dark  current  value    only.  It  was  shown  that  the  light-sensitive  phase  is monoclinic  2  corresponding  to  Cd 0.53 Se 0.47  formula  determined  by  the  X-Ray,  SEM  and  elementary analysis tool methods.
