a new fabrication method for multicrystalline silicon layers

Novel method for integrating silicon CMOS and

In FIG. 17, several layers can be distinguished: the polycrystalline silicon carbide substrate, the silicon planarization layer, single crystal silicon layer, and the buried oxide. As a result, clear advantages have been demonstrated over the conventional art devices, which have poor thermal conductivities arising from the utilization of oxide bonding layers.

An Innovative Light Trapping Structure Fabrication Method

An innovative fabrication method of light trapping structures on the surface of diamond‐wire‐sawing multi‐crystalline silicon (DWS mc‐Si) is proposed, which may trigger new progress in photovoltaic (PV) industry. A simple pre‐etching step with HNO 3 /HF solution is used to remove the saw marks of the wafers as well as amorphous silicon layers, and form vermicular micro‐hollows.

Simulation of device parameters of high ef ciency multicrystalline silicon solar cells

Multicrystalline silicon (mc-Si) solar cells account for around 50% of the total solar cell production. According to the January 2011 issue of Solar Industry (Magazine Article, 2011), mc-Si technology represents roughly 80% of the c-Si market on a dollar per watt

A surface of a multicrystalline silicon substrate is etched with an alkaline aqueous solution in a condition so that a surface area-to-planar surface area ratio R is smaller than 1.1. A multiplicity of fine textures are formed over the irregularities by dry etching. This

Reflectance control for multicrystalline

A new texturing method especially for multicrystalline silicon solar cells was investigated. This technique is based on a maskless acidic etching of silicon. It can texturize surfaces quite homogeneously in a short time and eliminate a saw damage removal process.

Silicon Growth Technologies for PV Applications

2016/10/10Crystalline silicon is the most used semiconductor material for solar cell applications accounting for more than 90% of the market share. Nowadays, multicrystalline and monocrystalline silicon are mainly produced from directional solidification and Czochralski method, respectively. Solar cells made of these two types of material have shown efficiencies below the theoretical limit due to the

Atomic force microscopy (AFM) and Raman spectroscopy reveal that the as-grown ultrathin MoSe 2 layers change from a single layer to a few layers. Photoluminescence (PL) spectroscopy demonstrates that while the multi-layer MoSe 2 shows weak emission peaks, the monolayer has a much stronger emission peak at ∼1.56 eV, indicating the transition from an indirect to a direct bandgap.

Polycrystalline silicon

Polycrystalline silicon, or multicrystalline silicon, also called polysilicon or poly-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process.

Top-down fabrication of silicon SiNWs can be produced by many different methods, normally divided into bottom-up growth mechanisms and top-down etching processes. While growing of SiNWs normally is conducted by using the vapor-liquid-solid (VLS) mechanism [ 14 ], which needs high temperatures, toxic gases and expensive vacuum equipment, top-down etching can be performed in easier ways.

Here, we developed a novel stereolithographic (SLA) 3D printing method that, for the first time, can be used to fabricate multi-layer constructs (polypills) with variable drug content and/or shape. Using this technique, six drugs, including paracetamol, caffeine, naproxen, chloramphenicol, prednisolone and aspirin, were printed with different geometries and material compositions.
