"Investigations of materials and metasurfaces for solar cells efficiency optimization"


Photovoltaic technology has established itself as one of the main contenders to replace fossil fuels as the principal source of energy, due to worldwide accessibility of sunlight, and the minimal impact this technology has on the environment. Extensive research has been conducted in the fields of materials science, metasurfaces engineering, and optics, which has led to an increase in the efficiency of solar cells from 14% to 40%. This enhancement has been made possible by means of doping, device structure optimization, or addition of light-trapping surfaces. This talk explores a series of studies and simulations carried out on material properties, metasurface designs, and device structures, with the purpose of solar cells efficiency optimization.
