This paper presents the first attempt to learn semantic boundary detection using image-level class labels as supervision. Our method starts by estimating coarse areas of object classes through attentions drawn by an image classification network. Sinc

Photovoltaic devices based on the copper–indium–gallium–selenium (CIGS) materials system are limited to thermal cycles below 350 °C. This is an obstacle for making higher performance devices and a significant barrier to building multi-junction

Thin-film photovoltaic research based on ternary or quaternary absorber materials has mainly concentrated on copper (indium/gallium) diselenide, CuIn x Ga 1-x Se 2 (CIGS). This material has demonstrated exceptional energy conversion efficiencies. By

Molybdenum (Mo) back contacts have been widely used for thin film based solar cells, especially for CuIn1-xGaxSe2 (CIGS) and Cu2ZnSnS4 (CZTS) based devices. Traditionally, a bilayer approach at two different sputtering pressures is used to produce hi

The saturation of V O c at larger band gaps in Cu(In, Ga)Se 2 devices presents a major challenge in developing high efficiency solar devices for tandem solar applications. Although recent studies have shown that recombination at the buffer/absorber i

A vast majority of existing sub-millimeter-scale sensors have a planar, 2D geometry as a result of conventional top-down lithographic procedures. However, 2D sensors often suffer from restricted sensing capability, allowing only partial measurements

Spectroscopy of planetary nebulae (PNe) provides the means to investigate s-process enrichments of neutron(n)-capture elements that cannot be detected in asymptotic giant branch (AGB) stars. However, accurate abundance determinations of these element

CuInxGa1-xSe2 (CIGS) solar cell junction properties were tailored by altering the buffer layer properties by chemical bath deposition method. An efficiency of > 12% was observed in large area of 5 cm2. Thickness of the CdS buffer layer was measured b
