Additionally, the use of perovskites with mixed cations and halides as luminescent materials has significantly improved the stability of perovskites in optoelectronic devices, attracting the interest of many researchers. Given that conventional polymerization techniques for fabricating luminescent solar concentrators, such as thermal and photopolymerization methods, are time-consuming and costly, a luminescent solar concentrator based on low-cost polyamide epoxy resin was fabricated using a triple-cation perovskite. This concentrator, with a simple fabrication process and no need for specific environmental conditions, was produced in customizable dimensions and exhibited a 170% increase in relative efficiency.</span></span><br> &nbsp; Epoxy resin, Luminescent Solar Concentrator (LSC), Optical properties, Triple-Cation Perovskite. 207 212 http://ijop.ir/browse.php?a_code=A-10-152-1&slc_lang=en&sid=1 Sohrab Ahmadi-Kandjani s_ahmadi@tabrizu.ac.ir 10031947532846005466 10031947532846005466 Yes aPhysics of Optics & Lasers Department, Faculty of Physics, University of Tabriz, Tabriz, Iran.
