    摘要: The invention relates to a multi-junction solar cell comprising at least two sub-cells based on silicon and at least one material other than silicon, wherein a first sub-cell is designed to use photons in a spectral region of a shorter wavelength than a spectral region of a longer wavelength of a second sub-cell, the second sub-cell being based on silicon and the first sub-cell being based on a material which has a larger band gap than silicon, wherein the first sub-cell and the second sub-cell are designed as a monolithic unit consisting of a layer stack, and wherein the first sub-cell and the second sub-cell are electrically connected to one another in series by means of a tunnel diode, such that the tandem solar cell is equipped with two terminals, wherein the tunnel diode has a tunnel diode n layer and a tunnel diode p layer. The problem addressed is that of proposing a multi-junction solar cell of simple construction. The problem is solved by multi-junction solar cells in which the tunnel diode n layer and/or the tunnel diode p layer is/are silicon-based layer(s).

    摘要: A metal electrode structure for a solar battery and a battery assembly are provided. The structure of the metal electrode for the solar battery includes multiple main grid lines provided parallel to one another and multiple fine grid lines perpendicular to the main grid lines. Spacing between adjacent two main grid lines is defined as L, and a distance between two end points of each fine grid line is less than L. And connecting ends of adjacent two fine grid lines of the multiple fine grid lines between adjacent two main grid lines are connected to different main grid lines of the adjacent two main grid lines.
