Energy transfer examination of Er3+/Nd3+ to produce a high-performance light conversion layer for enhancing the solar cells' efficiency
Abstract
Aiming to enhancing the solar cells efficiency, a spectral upconversion layer of a developed oxy-fluorophosphate glass containing Er3+/Nd3+ ions will be produced. The structural changes resulting from the penetration of Nd3+ ions into the glass network will be examined using X-ray diffraction, density and density-based parameters, Fourier transforms infrared, spectra, and Raman spectra. Being a major nerve in the spectral conversion layers, the thermal stability of the produced glasses will be investigated by studying the temperature of glass transition and crystallization using differential scanning calorimetry. Under the influence of appropriate wavelengths, the studied glasses will be pumped, and the resulting light emission will be examined to explore its efficiency as conversion layers for solar cells.
Keywords: Solar cell, light upconversion, Er3+/Nd3+, oxy-fluorophosphate glass.
