Abstract:
plasmonic solar cells are promising alternatives for expensive conventional bulk solar cells due to their unique light trapping properties and easy growth processes. Here we represent optical and electrical characteristics of a silicon asymmetric based plasmonic solar cell with nona particle architecture arrays, and compare its performance with symmetric and asymmetric nano particle solar cells. We describe the strong optical absorption of our proposed design by finite-difference time domain simulations. Nano particle show 13% enhancement in short current density, even in different angles of incident light, compared to cylindrical nano particle. This improved performance is due to efficient light confinement of plasmonic by increasing light trapping path for waves that are trapped inside the nano particle and conducting the waves that located in free space into the nano particle and substrate.
Plasmonics is based on the process of interaction between electromagnetic waves and conduction electrons in nano-sized metals. Data transmission is currently occurring through copper conduction through electrons, but in plasmonics, oscillating positive nuclei occur, and plasmons are considered for frequencies up to 100 terahertz, while typical wires are at 10 gigahertz Are very popular. In this thesis, several new structures for solar cells using gold and silver nanoparticles are proposed, which is proposed in the proposed structure, which uses nanoparticles of gold at the surface and the end of the solar cell, to be 14.47 millivolts per centimeter Square meters for maximum output power and 83/71 percent for fill factor. In a structure that uses the diameter of the silver nanoparticles in a solar cell, we arrived at a short-circuit current density of 21.54 mA cm2, and in the case of three-dimensional particles in the solar cell, the short-circuit current density was 26 / 78 mA per cm..
