Abstract: A preparation method of a heterojunction solar cell includes following steps: depositing a first passivation layer on a first surface of a silicon substrate by using a gas source, a base material of the first passivation layer being hydrogenated amorphous silicon; during depositing hydrogenated amorphous silicon of the first passivation layer, allowing the gas source to gradually incorporate carbon dioxide, and controlling a proportion of carbon dioxide in the gas source to gradually increase with increase of a thickness of the first passivation layer which has been deposited.

Abstract: A solar cell is provided, includes: a substrate, a first passivation layer, an emission layer, a first conductive layer, a second passivation layer, a back surface field layer and a second conductive layer. The first passivation layer, the emission layer and the first conductive layer are sequentially disposed on a surface of one side of the substrate, and the second passivation layer, the back surface field layer and the second conductive layer are sequentially disposed on a surface of another side of the substrate. The first conductive layer includes a first transparent conductive oxide layer, a first conductive metal layer and a second transparent conductive oxide layer which are sequentially stacked.

Abstract: The present application provides a transparent conductive oxide film and a heterojunction solar cell, which relates to the technical field of solar cells. The transparent conductive oxide film includes a seed layer, a conductive layer and a protection layer. The seed layer includes an indium tin oxide film or a gallium/aluminum co-doped zinc oxide film. The conductive layer is a gallium/aluminum co-doped zinc oxide film. The protection layer is an indium tin oxide film. The thickness of the indium tin oxide film in the transparent conductive oxide film is smaller than the thickness of the gallium/aluminum co-doped zinc oxide film. It can ensure battery efficiency and reduce battery attenuation, while reducing costs.

Abstract: A method to correct amplification bias in amplicon sequencing is disclosed. Amplification efficiency is not constant among different loci in a sample, nor for the same locus in different samples. Differences in 3?-end stability, primer Tm, amplicon length, amplicon GC content, and GC content of amplicon flanking regions all may contribute to amplification bias. Such bias interferes with accurate calculation of copy number for a genomic region of interest and hinders the application of amplicon sequencing for detection of minor copy number variation. The methods of the invention allow correction of amplification bias and enable detection of minor copy number variation using amplicon sequence data.

Abstract: An image preprocessing module is provided by the present invention to pre-process pathological images through superpixel segmentation in the cloud infrastructure, and meanwhile stores the boundary thereof by using the binary image; and performing multi-user data recording by the data recording module, so that the user can collaborate on image annotation; through the front-end interaction module, the capturing action of the user and displaying the pathological image; through the back-end processing module, the responding to the request sent by the front-end interaction module and completing the annotation of the data and the suggesting possible annotation sub-regions to the users. Through the effects achieved by the above modules, the present invention accomplishes the purpose of multi-user collaborative and convenient pixel-level annotation on pathological images via a webpage.

Abstract: An excess heat recovery apparatus and process for high temperature chlorine dioxide bleaching of pulp is provided. The pulp of the high temperature chlorine dioxide bleaching stage enters a tube-side of a chlorine dioxide preheater through a pipeline. The low-temperature chlorine dioxide in the storage tank enters a shell-side pipeline of the chlorine dioxide preheater. 0.5 mol/L of a stabilizer may be added during preheating to prevent ClO2 from decomposing during the heating process. Preheated chlorine dioxide is then moved into a pulp mixer and the pH is adjusted to 3.2-3.8. The mixed pulp is then moved into a high temperature chlorine dioxide bleaching tower for bleaching. The cooling pulp, now out of the preheater, is washed in an alkaline extraction stage. The waste water from the washing flows directly into an effluent treatment system and is recycled after treatment.

Abstract: Materials and methods for processing a cell population, such as enriching for a cell of interest from a cell population, are disclosed. The method may include: obtaining a cell population dispersed in a cytocompatible matrix; applying one or more labels to the cell population to distinguish a cell of interest from one or more cells of the cell population; identifying a portion of the cytocompatible matrix containing the cell of interest; and optionally isolating the portion of the cytocompatible matrix containing the cell of interest. The methods may, for example, advantageously provide reduced cell damage or loss relative to other procedures. Also disclosed are devices and compositions that may be useful for performing the methods.

Abstract: Apparatus and Methods are provided for a microfabricated fluorescence activated cell sorter based on a switch for rapid, active control of cell routing through a microfluidic channel network. This sorter enables low-stress, highly efficient sorting of populations of small numbers of cells (i.e., 1000-100,000 cells). The invention includes packaging of the microfluidic channel network in a self-contained plastic cartridge that enables microfluidic channel network to macro-scale instrument interconnect, in a sterile, disposable format. Optical and/or fluidic switching forces are used alone or in combination to effect switching.
