Abstract
Three-dimensional printing technologies represent a revolution in the manufacturing sector because of their unique capabilities for increasing shape complexity while reducing waste material, capital cost, and design for manufacturing. This project focuses on developing 3D printing technologies for the fabrication of Lumenesence solar concentrators. The use of 3D printing technology in this field is of special interest owing to the high-quality polymerization of the host material which otherwise presents strong limitations in shape and functionality when processed with traditional manufacturing methods. CH3NH3PbBr3 perovskite quantum dots are introduced as luminescent materials in these sheets and half-cylindrical LSCs. The smaller redshift of PL peak and also a lower PL intensity reduction in 2mm-LSC imply lower reabsorption loss in thinner QD based sheet LSC. The optical efficiency of 3.94% is obtained for 2mm-LSC due to higher waveguide efficiency in this LSC. Characterization of sheet LSCs with edge-mounted solar cell shows PCE of 6.64% and 2.73% for LSCs with 2mm and 5mm thicknesses, respectively. It is shown that half-cylindrical LSCs act as a lens to concentrate the incident light into the solar cell, which results in boosting the PCE of these LSC devices with respect to the sheet LSCs. Characterization of half-cylindrical LSCs with bottom mounted configuration is measured with three different backscatters. It is demonstrated that the backscatter has a major role in half cylindrical LSCs, in which the white background could scatter the lost incident light more effectively back to the LSC and hence boost the solar cell efficiency. Comparison of QD based half-cylindrical LSCs with Rhodamine 6G based ones results in better performance of QD based LSCs. Also, the performance of the parabolic 3D printed LSCs has been investigated. Eventually, parabolic shape LSC can boost the attached solar cell. The home-made system has been manufactured for absorption and IPCE measurement purposes and ran under several tests for accuracy confirmation. As a computational analysis, the parabolic LSCs with fixed-width (2 mm) and variable thickness (0.25-3 mm) have been simulated by COMSOL. Based on the outcomes, the optimized thickness is 1-1.5 mm.
