II-IV Semiconductors for Optoelectronics: CdS, CdSe, CdTe

  title={II-IV Semiconductors for Optoelectronics: CdS, CdSe, CdTe},
  author={Minoru Isshiki and Jifeng Wang},
Owing to their suitable band gaps and high absorption coefficients, Cd-based compounds such as CdTe and CdS are the most promising photovoltaic materials available for low-cost high-efficiency solar cells. Additionally, because of their large atomic number, Cd-based compounds such as CdTe and CdZnTe, have been applied to radiation detectors. For these reasons, preparation techniques for these materials in the polycrystalline films and bulk single crystals demanded by these devices have advanced…
