A study on light sensitization behavior in (Mph)2CuCl4 low-dimensional hybrid material with tetrahedral units and extended absorption up to the NIR region

Abstract

Abstract To develop toxic-free hybrids and hybrid perovskites with transition metals, copper is a potential candidate moreover, Cu settles to a layered structure with higher stability. Depending on the size of the organic cation, the organic inorganic copper halide hybrid settles into a lower dimensional perovskite structure or as a lower dimension hybrid material which lack the octahedral factor and form a regular array of tetrahedral units with organic cations affixing to them. Due to their unique optical properties, these hybrid structures have been comprehensively investigated for light emitting applications. According to the structural study, the synthesized morpholinum copper chloride ((Mph)2CuCl4) hybrid has inorganic tetrahedral units organized in layers, with organic bilayers between them. The band gap of the material was found to be 1.44 eV with good absorbance. This work examined the light sensitization properties of the organic inorganic hybrid semiconductor (Mph)2CuCl4. For that, a device of structure fluorinated tin oxide glass substrate/TiO2 compact layer/TiO2 mesoporous layer/(Mph)2CuCl4/Spiro-OMeTAD/Au was fabricated and encountered solar cell parameters and impedance.
