We describe a laboratory-scale process for recycling rare earth metals from end-of-life rare-earth/iron/boron alloy permanent magnets using a 2-h chlorine gas treatment at 673 K. This treatment does not require any special preparation of the magnets;

An electrochemical cell containing molten Li2CO3-Li2O has been proposed for the conversion of the greenhouse gas CO2 to CO, which can then either be used to power gas turbines or converted to methanol. Since efficient electrolysis takes place at 900

The photovoltaic performance of solar cells, based on a Cu(In1-XGaX)Se2 (CIGS) absorber layer, is directly correlated with Ga composition. We have used scanning capacitance microscopy and conducting probe atomic force microscopy (CP-AFM) to provide m

Compositional uniformity of Cu(In,Ga)Se2 (CIGS) solar cells was studied, using thin cross sections of complete cells prepared by focused ion beam (FIB) and examined in the transmission electron microscope (TEM). This methodology revealed the composit

Despite many recent research efforts, the influence of grain boundaries (GBs) on device properties of CuIn1−xGaxSe2 solar cells is still not fully understood Here, we present a microscopic approach to characterizing GBs in polycrystalline CuIn1−x

Thermally oxidized 0.1 and 1 μm thick n-type PbTe:In films were studied in this work. Two main processes induced during the thermal treatment in oxygen atmosphere were identified. These are the formation of an oxide phase on the surface and generati

Irradiation by the beam of the scanning electron microscope is shown to induce a systematic decay of the cathodoluminescence intensity in gallium nitride semiconductor doped with carbon. This decay is accompanied by increased electronic carrier diffu

The superior performance of certain polycrystalline (PX) solar cells compared to that of corresponding single-crystal ones has been an enigma until recently. Conventional knowledge predicted that grain boundaries serve as traps and recombination cent
