Title:
SOLAR CELL DEVICE AND MANUFACTURING METHOD THEREFOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/035180
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a solar cell device and a manufacturing method therefor, and an electronic device. The solar cell device may comprise a first electrode, a second electrode, and a light absorbing layer, wherein the first electrode comprises a first conductive electrode; the second electrode comprises a second conductive electrode; the light absorbing layer is located between the first conductive electrode and the second conductive electrode; the first electrode further comprises a first bus electrode; the first bus electrode is connected to the periphery of the first conductive electrode; and the sheet resistance of the first bus electrode is smaller than the sheet resistance of the first conductive electrode, that is, in the first electrode, the sheet resistance of a peripheral region is smaller than the sheet resistance of a central region. In this way, compared with a first electrode comprising only a single first conductive electrode, the sheet resistance of the first electrode is reduced, and photocharges transmitted to the first conductive electrode can quickly gather to the periphery, reducing sheet resistance loss caused by long-distance uneven transmission of photocharges, thereby facilitating the collection of the photocharges, thus improving photoelectric conversion efficiency of the solar cell device.
