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: The invention provides a temperature sensitive cell culture surface and preparation method thereof. The preparation method comprises the following steps: (1) preparing a temperature sensitive primary liquid by adding a temperature sensitive compound and a free radical into a solvent, mixing and dissolving the same, and obtaining the temperature sensitive primary liquid; and (2) distributing the temperature sensitive primary liquid on a cell culture surface, and leaving the cell culture surface at 50-150° C. to react for 5-120 mins.

Abstract: A coverslip for cell culture, capable of achieving seamless adhesion between the coverslip for cell culture and a target culture device, so as to solve the technical problem that cell suspension flows into gaps between the coverslip and a culture dish. Moreover, the coverslip for cell culture has exquisite structure, and is easy to carry out batch experiment and comparison. The coverslip is flake-like with upper and lower surfaces being parallel to each other, and comprises: a coverslip substrate (1) and sub-coverslips (2); the coverslip substrate (1) is provided with at least N hollowed-out parts (11); the sub-coverslips (2) are fixedly connected in the hollowed-out parts (11) by means of M fragile connecting pieces (3), wherein both N and M are natural numbers which are not related to each other.

Abstract: A three-dimensional cell culture scaffold and preparation method thereof. The preparation method comprises the following steps: designing, according to a shape of a cell culture device, a shape of the three-dimensional cell culture scaffold; printing once by a 3D printer to form the three-dimensional cell culture scaffold; performing a surface treatment, by a surface treating agent, on the three-dimensional cell culture scaffold manufactured by 3D printing to obtain a resultant three-dimensional cell culture scaffold. By adopting a three-dimensional printing technology to manufacture a three-dimensional fibrous cell culture scaffold having a three-dimensional fibrous network structure, raw materials and a manufacturing time can be saved, reducing production costs, increasing production efficiency, decreasing power consumption, preventing a flaw in the conventional manufacturing technique, and facilitating large-scale intelligent manufacturing.

Abstract: Provided are cell culture apparatus and method. The cell culture apparatus comprises a culture column and a perfusion system, the culture column comprising a first and a second tube-connecting caps and a support for cells to attach and grow thereon.
