Abstract
recently, It has been actively studied for the improving efficiency of Solar cell as an alternative energy of fossil fuel. at this experiment, silicon nano particles were applied for improving efficiency of perovskite solar cell as the hole transporting layer. silicon nano particles were synthesized from the reaction of magnesium silicide and ethylene diammonium chloride in chlorobenzene. Optical characterizations of Si-ncs were achieved by using ultraviolet-visible (UV-Vis) and photoluminescence (PL) spectroscopy. The blue photoluminescence emitting of sinps is at 435 nm with an excitation wavelength of 355 nm. the average size of sinps was 1.9-2.1nm that was achieved via Transmission electron microscopy and dynamic light scattering. perovskite has ABX3, organic inorganic complex crystal structure, A is organic cation, B is metal cation, X is halide anion for combining A, B cation. at this work, to use methylammonium lead triiodide, solar cell was fabricated. in this fabricating solar cell, anode was transparent materials, Indium tin oxide glass. hole transporting material, PEDOT-PSS was spin coated on the ITO glass. next all processes were in glove box filled by nitrogen gas. sinps ,perovskite, PC61BM were spin coated in sequence on the PEDOT-PSS layer. Sinp that is diluted 25times was the highest power conversion efficiency, Jsc, Voc. The efficiency was 9.8%, up 38% compared to reference, Jsc is 16.5mA/cm, Voc is 0.77V, the fill factor is 0.8.
