Solar technology of flexible Cu(In,Ga)Se2 (CIGS) thin film

Solar technology of flexible Cu(In,Ga)Se2 (CIGS) thin film


  • Cu(In, Ga)Se2 (CIGS) compound semiconductor has a direct-transition-type energy bandgap. Also, because of its highest light absorption coefficient among all semiconductors, it is possible to manufacture a high-efficiency solar cell with a thin film of 1 ~ 2 ㎛ thickness.
  • The thin film solar cell with metal or plastic substrate instead of traditional glass substrate has a high output ratio.
