Mixed Organic Halide Perovskite Energy Harvester for Solar Cells

Abstract

Organic- inorganic hybrid perovskite shows promising properties such as optical, electrical, and magnetic. To address issues in the standard methylammonium lead iodide perovskite such as toxicity and stability, lead was replaced with Cu in metal ion part and iodine replaced by chlorine in the anionic position. In this work, methyl ammonium copper chloride (MA2CuCl4) and phenyl ethyl ammonium copper chloride (PEA2CuCl4) were synthesised. Optical and structural property variations of solution obtained by mixing MA2CuCl4 and PEA2CuCl4 in 1:1 ratio was studied. Methylammonium lead iodide has a wide range of applications, particularly in solar cells and photovoltaic systems. Phenylethyl ammonium copper chloride material exhibits both ferroelectric and ferromagnetic properties. Methylammonium copper chloride is hygroscopic and unstable. To increase the stability of the material the organic part can be replaced with higher-order functional groups. Phenylethyl ammonium copper chloride is found to be thermally stable and has more moisture resistance ability compared to methyl ammonium copper chloride. From angle of efficiency, methyl ammonium copper chloride possessed higher performance than phenylethyl ammonium copper chloride, particularly in the field of solar cell perovskites. Uv-vis spectroscopy, FE-SEM, XRD, FTIR characterizations were done.

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

“…The first peak spans the wavelength range from 240 to 563 nm, and the second peak spans from 563 to 870 nm. In most reported cases, Cu-based HOIPs and HOIHs have narrow multiple absorption peaks spanning the UV-Vis-NIR wavelength range [27,[39][40][41]. We obtained two broad peaks across the region with enough absorbance for light sensitization here, which prompted us to examine the use of (Mph) 2 CuCl 4 in solar cells.…”

The effect of precursor concentrations on the structure and optoelectronic properties of quasi low-dimensional hybrid 2-methylpyridinium lead bromide crystalline phases

“…Keeping in mind the structure-property relationship, this approach paves the way to the design of materials that are interesting from both fundamental research and industrial applications perspectives. They can be formed from numerous organic 4,9,[21][22][23][24] and inorganic 21,25,26 cations, halide anions, and their mixtures, 21,[27][28][29] leading to technologically promising optical, 21,30 physico-chemical, 31 and electrical 10,30 properties. The structure-property relationship is most prominent in the case of quasi low-dimensional hybrid organometal halides with aromatic organic cations.…”
