Sb2S(e)3 is good light absorber because Sb2S(e)3 has strong absorption coefficient, large dipole moment which enable separate charge easily and suitable band gap for adapting solar cells. However, it is difficult to achieve the efficient solar cells because we can not synthesize the highly pure Sb2S(e)3 by conventional methods such as chemical bath deposition (CBD) and single source precursor (SSP). Conventional methods cause the impurity, which degrade the power conversion efficiency of solar cells. Therefore, we suggest the developed method to synthesize the highly pure Sb2S(e)3 by using hydrazine solution. Through the hydrazine method, we synthesized the highly pure Sb2S(e)3 and adapted these materials for fabricating the solar cells. The Sb2S(e)3 sensitized thin film solar cells exhibited 14.67 Jsc (short circuit current), 0.39 Voc (open circuit voltage), 52.61 F.F. (fiil factor), and 3.01 η(power conversion efficiency). |
