| dc.description.abstract | In recent years, inorganic halide perovskites have come up as a great al ternative for hybrid organic-inorganic perovskites for photovoltaic applications. Methyl ammonium lead halide, although quite popular for its large power conversion efficiency and manufacturing ease, has certain draw backs owing to structural denaturation when exposed to UV rays, heat and moisture, and due to the toxicity of Pb element. An all inorganic halide perovskites like RbGeI3 can be an alternative, as the cations have similar configurations to the organic-inorganic counterpart, but they make up for the drawbacks the latter has. We studied the structural, electronic, and optical properties a particular phase- pn21a phase of RbGeI3to deter mine its suitability as a photoabsorber. We analyzed the material through DFT, which is a powerful approximation tool for many-electron systems like solids. Our compound shows a direct bandgap of 1.16 eV, and a wide absorption spectrum is observed in UV-Visible range, indicating this com pound can be a good photoabsorber. | |
