Abstract
Solar energy is usually difficult to utilize efficiently once it reaches the building through the window glass. Smart glass regulates and utilizes the solar energy spectrum through its material and structural properties, greatly improving the utilization of solar energy. This article offers a multilayers structure smart glass with a metal-particle-doped photovoltaic material layer, which can reach selective transmission of human eye spectral response and relatively high photoelectric conversion efficiency. Four typical doping combinations were calculated and optimized by a multi-island genetic algorithm to obtain structural parameters that give better performance. Under the optimized weighting of 1:1, the average transmittance in the spectral response range of the eye can reach more than 0.75, while the photovoltaic conversion efficiency is between 0.1 and 0.2 or greater than 0.2. The work in this paper provides a reference for the design of smart glass structures to improve the energy efficiency of buildings.
