RT info:eu-repo/semantics/article T1 Evolution of the external quantum efficiency of Si-based PV minimodules with encapsulated down-shifters and aged under UV radiation A1 González Díaz, Benjamín Jesús A1 Saw, Min Hsian A1 Hernández Rodríguez, Cecilio A1 Sanchiz, Joaquín A1 Khoo, Yong Sheng A1 Guerrero Lemus, Ricardo K1 lanthanides K1 down-shifters K1 aging K1 UV radiation K1 luminescence AB For the first time to our knowledge, a study about the increase in external quantumefficiency (EQE) by down-shifters (DS) encapsulated by industrial procedures onphotovoltaic (PV) modules is presented. EQE improves substantially in the UV range notonly because of the optical path optimization for photons reaching the solar cell, but alsoit is attributed to the substantial reduction of DS photons scattered out of the solar cellwhen the outermost surface of the DS layer is embedded in ethyl-vinyl-acetate.Consequently, a proper encapsulation of DS layers is required for the optimalcharacterization of EQE. Moreover, the encapsulation of the DS layer substantiallyreduces the degradation of its luminescent properties due to UV radiation. However, thereduction of the EQE under UV radiation for the encapsulated DS layer is still high andshould be substantially reduced for the integration of down-shifting properties in thelamination process of PV modules.
