Although alternatives such as Freon gases (e.g.,
dichlorofluoromethane) have been used, Cd[Cl.sub.2] still remains a commonly exploited chemical to produce high efficiency solar cells.
Nitrobenzene and chloroflorocarbons (
dichlorofluoromethane, dichlorodifluoromethane and trichlorofluoromethane) complexes (5-7) showed interactions in the same fashion i.e through single oxygen of nitrobenzene and chlorine atom of chlorofluorocarbons, was very similar as we observed in case of all halogen complexes.
