  • Publication number: 20240047593
    Abstract: A thin film photovoltaic structure has a substrate, a first conductive layer, a photovoltaic layer, a second conductive layer, multiple serial connection conductive layers and multiple first insulating areas. By using the serial connection conductive layer, each width between each adjacent serially connected photovoltaic structures is reduced, and an effective area of the thin film photovoltaic structure for collecting optic energy is increased, thus enhancing a geometry fill factor of the thin film photovoltaic structure. Further, by using the serial connection conductive layer and the first insulating area to form contact overlap areas in an overlapping arrangement, it can effectively protect conductive areas in the first conductive layer when etching the second conductive layer during the manufacturing process, which prevents the conductive areas from being damaged to not act as electrodes, and efficiently increases a manufacture yielding rate of the thin film photovoltaic structure.

  • Patent number: 11809667
    Abstract: A transparent conductive substrate structure used for a thermoforming process includes a transparent cover plate and a touch sensing layer structure. The transparent cover plate includes a toughening layer on one side thereof. The touch sensing layer structure arranged on one surface of the toughening layer, and includes a first transparent conductive layer, a dielectric layer, a barrier layer, a second transparent conductive layer, and a buffer protective layer. Each transparent conductive layer is directly applied to the transparent cover plate, so that the thickness between the transparent conductive layers is below 1 ?m. The thickness between layers may be reduced to increase the sensitivity of the touch sensing layer structure. To prevent each transparent conductive layer and an electrode wire layer from breaking during the thermoforming process, the transparent conductive substrate structure is combined with the buffer protective layer to strengthen the structure of each transparent conductive layer.

  • Publication number: 20230142280
    Abstract: A capacitive sensing identification tag includes a substrate and a touch sensing layer disposed on one side of the substrate. The touch sensing layer includes high-sensing regions and low-sensing regions with different shapes. Both the high-sensing regions and the low-sensing regions have different stacked conductive layers and dielectric layers. A difference between the high-sensing regions and the low-sensing regions is that each of the high-sensing regions contains a dielectric layer, while each of the low-sensing regions does not. The capacitive sensing identification tag achieves an effect of sampling and identification of a touch panel by a capacitive sensing quantity that is different from a capacitive touch panel. And the capacitive sensing identification tag will not cause a difference in color or light transmittance between the high-sensing regions and the low-sensing regions, so there is no visible difference between the high-sensing regions and the low-sensing regions.
