Study of MASrCl3 and MASr(1-x)Sn(x)Cl3 Perovskite As Light Harvesting Material in Optoelectronic Devices

In the past decades, the organic-inorganic halide perovskites (OHIP) based materials are the fast developing area in the field of material science. It has tremendous growth in the new generation of optoelectronic devices, such as solar cells, light emitting diode and photodetectors. It is inexpensive, easy to process and highly crystalline in nature. It also has the disadvantages that the compounds contain toxic lead ions in their inorganic part. To overcome the toxicity of leadcontaining material, we have synthesized strontium based organic-inorganic halide perovskites as the alternative material. The newly synthesized MASrCl3 and MASr(1-x) Sn(x)Cl3 has been characterized by x-ray diffraction, UV-Visible spectroscopy and photoluminescence for the analysis of crystalline, absorption and emission properties. This shows good absorption and emission properties for solar cells, LEDs, photodetector applications.
