We studied the twins structure, optical properties, electrical properties and cell performance of chlorine doped CdTe (CdTe:Cl) polycrystalline film deposited by magnetron sputtering. Serried twins structure consisting of only several atomic layers can be found in both as-deposited CdTe:Cl and CdTe:Cl with annealing. Relatively heavy chlorine doping by magnetron sputtering may also cause rapid donor-acceptor pair (DAP) recombination. These cause the series resistance of CdTe:Cl film to be too high compared to undoped CdTe film with CdCl 2 treatment.
