Yilmaz, P. (author), de Wild, J. (author), Aninat, R. (author), Weber, T. (author), Vermang, B. (author), Schmitz, J. (author), Theelen, M. (author)A post-mortem analysis is conducted after potential-induced degradation (PID) of a commercial copper-indium-gallium-selenide (CIGS) photovoltaic module. After PID, the conversion efficiency of the total module decreased by 62%. Electroluminescence images of the module show that the edges of the modules were much more affected by the PID than the...article 2023

(author), Shukla, S. (author), Vermang, B. (author), Van Bael, M. (author), Hardy, A. (author)A new benign aqueous route toward bismuth-containing photoelectrodes is proposed to eliminate the need for harmful organic solvents and/or acids. A CuBi2O4 photocathode is prepared by stabilizing the metal ions through complexation in pH neutral aqueous solutions. Merits of the proposed approach are elemental homogeneity (with unique doping...article 2023

(author)Monolithic two-terminal (2T) perovskite/CuInSe2 (CIS) tandem solar cells (TSCs) combine the promise of an efficient tandem photovoltaic (PV) technology with the simplicity of an all-thin-film device architecture that is compatible with flexible and lightweight PV. In this work, we present the first-ever 2T perovskite/CIS TSC with a power...article 2022

(author)The solid-state hydration of salts has gained particular interest within the frame of thermochemical energy storage. In this work, the water vapor pressure-temperature (p-T) phase diagram of the following thermochemical salts was constructed by combining equilibrium and nonequilibrium hydration experiments: CuCl 2 , K 2 CO 3 , MgCl 2 ·4H 2 O,...article 2019

Blanker, J. (author), Vroon, Z.A.E.P. (author), Zeman, M. (author), Smets, A. (author)Copper-indium-gallium-di-selenide (CIGS) is the present record holder in lab-scale thin-film photovoltaics (TF-PV). One of the problems of this PV technology is the scarcity of indium. Multi-junction solar cells allow better spectral utilization of the light spectrum, while the required current generation per layer is much lower, allowing much...conference paper 2018

van de Wiel, H.J. (author), Vardøy, A.S.B. (author), Hayes, G. (author), Fischer, H.R. (author), Lapadatu, A. (author), Taklo, M.M.V. (author)A flux-less copper-tin (Cu-Sn) solid-liquid inter-diffusion (SLID) bonding process, providing a cost-effective hermetic vacuum sealing at wafer-level, has been investigated. Observations have been made indicating that the storage time of Cu-Sn plated wafers before bonding is critical with regard to voiding. Growth of the intermediately formed...conference paper 2012

Gubbels, G.H.M. (author), Kouters, M.H.M. (author), Dos Santos Ferreira, O. (author)In high power automotive electronics copper wire bonding is regarded as the most promising alternative for gold wire bonding in 1st level interconnects. In the Cu-Al ball bond interface the growth of intermetallic compounds can deteriorate the electrical and mechanical properties of the interconnection. A summary of the thermo-mechanical...conference paper 2012
