The invention relates to a method of interconnecting photovoltaic cells into a module by using a tape carrying tabbing wires. The tape makes possible to build modules at a reduced cost. In the tape method individual photovoltaic cells (1) are interconnected into modules by using electrical interconnecting conducting strips (21, 43, 52, 74a, 74b) carried by a tape (51). The strips are laid out on the topsides and backsides of the PV cells. The strips are cut in such a manner that the cells will be interconnected in series after lamination. The present invention concerns an improvement of the tape used in the tape method.

A solar module having at least two substring groups, each including an upper substring having solar cells connected in series and arranged in a matrix having two adjacent columns and a plurality of rows, and a lower substring having solar cells connected in series and arranged in a matrix having two adjacent columns and a plurality of rows. The lower and upper substrings include the same number of solar cells. A cross-connector interconnects the lower and upper substrings electrically in parallel forming the substring group. A bypass diode is arranged electrically in the cross-connector, and cross-connectors of each substring group are interconnected electrically in series. Two columns of the lower substring include a different number of solar cells and two columns of the upper substring include a different number of solar cells, such that the number of solar cells of the upper substring and of the lower substring is odd.

A back contact solar cell assembly and methods for its manufacture and assembly onto a panel for use in space vehicles are described. The solar cell assembly includes a compound semiconductor multijunction solar cell having a contact at the top surface of the solar cell, a conductive semiconductor element extending from the contact on the top surface to the back surface of the assembly where it forms a first hack contact of a first polarity type, and a second back contact of a second polarity at the back surface of the assembly electrically coupled to the back surface of the solar cell.

This application provides a solar cell, a method for preparing the solar cell, smart glasses, and an electronic device. The solar cell includes a first conductive layer, a second conductive layer, a first conductive lattice, a second conductive layer, and a functional layer. The functional layer is disposed between the first conductive layer and the second conductive layer, the functional layer is configured to absorb light and generate a photocurrent, and both the first conductive layer and the second conductive layer are configured to receive the photocurrent. The first conductive lattice is in contact with a surface that is of the first conductive layer. The second conductive lattice is in contact with the second conductive layer, and the first conductive lattice and the second conductive lattice are configured to output the photocurrent to the target device. This application can mitigate impact of a sheet resistance on cell efficiency.

A solar panel includes: a cell group in which a plurality of solar cells is arranged in one direction; and a connecting element for electrically connecting the solar cells to each other.

A high efficiency configuration for a solar cell module comprises solar cells arranged in an overlapping shingled manner and conductively bonded to each other in their overlapping regions to form super cells, which may be arranged to efficiently use the area of the solar module. Rear surface electrical connections between solar cells in electrically parallel super cells provide alternative current paths (i.e., detours) through the solar module around damaged, shaded, or otherwise underperforming solar cells.
