The toxicity and instability of lead- halide perovskite materials in the solar cells are
yet demands must be resolved to vie to find alternatives of free lead-based halide perovskites
and double perovskite materials. Here we report on the experimental synthesis of a new family
of lead-free inorganic halide double perovskites Cesium copper antimony chloride
(Cs2CuSbCl6) and perovskite Cesium copper chloride (CsCuCl3) as a based sensitizer of the
solar cells and studies of its characterize and optical properties of the Photo-Voltaic (PV)
device. The configuration structural of PV devices is (FTO/TiO2/CsCuCl3 or
Cs2CuSbCl6/Cu2O/Al electrode). The double perovskite Cs2CuSbCl6 and Perovskite CsCuCl3
are successfully synthesized, performed of structural investigations by X-ray diffraction, and
depicted of optical properties via optical absorption of UV−vis measurement. The perovskite
(CsCuCl3) belongs to the space grope P6122 and the Hexagonal structure phase. The strongest
peeks of the XRD diffraction pattern of the double perovskite Cs2CuSbCl6 are taken at the
reflection points (-201), (-202), (-3-11), (220), (-223) and (-5-34). From UV−vis measurements
obtained values of a direct gap of both (Cs2CuSbCl6) and (CsCuCl3) are (1.5 and 2.2) eV,
respectively. The optimum power conversion efficiency (PCE) of the PV device which used
Cs2CuSbCl6 as a sensitizer is 0.94%, the filling factor is 24%, the open-circuit voltage is 582.5
mV and the short circuit current was 2
