A four-pixel-array superconducting transition-edge sensor (TES) microcalorimeter with a mushroom-shaped absorber was fabricated for the energy dispersive spectroscopy performed on a transmission electron microscope. The TES consists of a bilayer of Au/Ti with either a 50nm or 120-nm thickness. The absorber of 5.0 μm thick is made from a Au layer and its stem is deposited in the center of the TE...

We propose and numerically investigate a novel perfect ultra-narrow band absorber based on a metal-dielectric-metal-dielectric-metal periodic structure working at near-infrared region, which consists of a dielectric layer sandwiched by a metallic nanobar array and a thin gold film over a dielectric layer supported by a metallic film. The absorption efficiency and ultra-narrow band of the absorb...

A coherent perfect absorber is essentially a specially designed Fabry-Perot interferometer, which completely extinguishes the incident coherent light. The one- and two-beam coherent perfect absorbers have been analyzed using classical electrodynamics by considering index matching in layered structures to totally suppress reflections. This approach presents a clear and physically intuitive pictu...

The non-toxic and wide bandgap material TiO2 is explored as an n-type buffer layer on p-type Cu(In,Ga)Se2 (CIGS) absorber layer for thin film solar cells. The amorphous TiO2 thin film deposited by atomic layer deposition process at low temperatures shows conformal coverage on the CIGS absorber layer. Solar cells from non-vacuum deposited CIGS absorbers with TiO2 buffer layer result in a high sh...

In this paper, the structure optimization scheme of multi-layer absorber on surface human tissue is designed. The uses graphite, foam and other materials to build a resistance loss layer. Solve electromagnetic parameters graphite through its characteristics, use equivalent transmission line theory calculate reflection coefficient. Establish objective function coefficient, genetic algorithm opti...

We report on heterojunction solar cells whose thin intrinsic crystalline absorber layer has been obtained by plasma enhanced chemical vapor deposition at 165°C on highly doped p-type (100) crystalline silicon substrates. We have studied the effect of the epitaxial intrinsic layer thickness in the range from 1 to 2.4 μm. This absorber is responsible for photo-generated current whereas highly dop...

In this work, a wire-shaped perovskite solar cell based on TiO2 nanotube (TNT) arrays is demonstrated for the first time by integrating a perovskite absorber on TNT-coated Ti wire. Anodization was adopted for the conformal growth of TNTs on Ti wire, together with the simultaneous formation of a compact TiO2 layer. A sequential step dipping process is employed to produce a uniform and compact pe...

Our primary goal is to increase the stabilized efficiency of thin film silicon solar cells in the substrate (nip) configuration by using textured substrates and tandem structures, based on amorphous (a-Si:H) and microcrystalline silicon (μc-Si:H). In order to reduce costs of mass-produced thin film solar modules, special attention has been paid in developing processes compatible with plastic fo...

Organic Solar Cells (OSCs) have a great potential for solar energy harvesting due to their low material cost and cheap production. The most common and promising type of OSC is the bulk-heterojunction (BHJ) OSC, which have shown power-conversion efficiencies of 8-10% [1]. The absorber layer in these OSCs consists of a mix of two phases; (i) a polymer, that serves as an electron donor, and (ii) a...
