    Abstract: A transfer method for micro flip chips includes forming a first bonding member on a surface of one side of a second electrical connection piece of each of a plurality of micro flip chips facing away from a temporary substrate to which they are adhered. The micro flip chips are transferred onto a drive substrate. The second electrical connection pieces of the micro flip chips are connected to a corresponding one of first electrical connection pieces of the drive substrate via the first bonding members. The micro flip chips are inspected to determine bad point positions of defective chips on the drive substrate. The first bonding member is irradiated at each bad point position by laser and the defective chip is removed. The method ensures stable bonding between the micro flip chips and the drive substrate and prevents the first electrical connection pieces from being damaged by laser irradiation.

    Abstract: The present application provides a positive electrode material for a lithium ion secondary battery and a preparation method therefor. The positive electrode material for a lithium ion secondary battery comprises polycrystalline particles of a ternary positive electrode material and a modifying material. The polycrystalline particles comprise a plurality of primary particles. The modifying materials are located on the surface of the polycrystalline particles and/or at the grain boundary interfaces between the primary particles, wherein the modifying material comprises an oxide of a positive pentavalent or positive hexavalent transition metal. By using the positive electrode material for a lithium ion secondary battery and the preparation method therefor of the present application, the problem of cracking of secondary particles of the material during the circulation process is avoided. Thus, the mechanical strength and structural stability of the ternary positive electrode material are effectively improved, and at the same time, the high-temperature cycle stability of the ternary positive electrode material is significantly improved, and the impedance increase during the cycle of the lithium ion secondary battery prepared thereby is effectively reduced.

    Abstract: A method for predicting performance of solar cell structure includes: collecting and extracting input feature parameters of solar cell structures and corresponding output feature parameters; establishing corresponding data sets, and preprocessing the data sets according to a known criterion; constructing a model by utilizing a machine learning algorithm, and setting structural parameters and performing initialization training on the model; performing training optimization on the model subjected to setting the structural parameters and performing the initialization training by using a preprocessed training data set to obtain a prediction model; and inputting a preprocessed test data set of a to-be-predicted solar cell structure into the prediction model to obtain predicted values of output feature parameters of the to-be-predicted solar cell structure. The performance of solar cell structure can be rapidly predicted, which is convenient to operate and has a high accuracy.

    Abstract: The present disclosure discloses a contact angle measuring device, including a light source, a container, a photodetector, a bubble generating unit, and a processing unit. The container includes a first and a second side walls that are opposite. The first side wall is made of a light-transmitting material, the container is filled with a liquid with light transmission inside. The monochromatic light emitted by the light source passes through the first side wall and enters an interface between the first side wall and the liquid. The bubble generating unit is configured for generating a bubble that is in contact with an inner surface of the first side wall. The photodetector is configured for detecting light intensity distribution of the monochromatic light through the liquid.
