Definitions

  • the present invention relates to a method for interconnection of solar cells. More specifically, the invention relates to interconnecting back-contacted solar cells during module assembly by tabbing and stringing.
  • Photovoltaic (PV) modules are generally manufactured by interconnection of several individual photovoltaic solar cells made from silicon wafers, each solar cell generating a relatively large amount of current delivered at a relatively low voltage typically between 0.5-0.8 Volts.
  • interconnection of the individual cells is generally performed in a way such that the negative terminal of one cell is connected to the positive terminal of another cell, i.e. the individual solar cells are connected in a series connection.
  • Such interconnection is generally achieved by soldering conductive wires, so called tabs, to the terminals of the different solar cells (see International Pat. No. WO 92/22929, J.T. Borenstein et al.).
  • the two polarity terminals are present at different surfaces of the cells, one of the terminals typically being at the back surface and the other terminal typically being at the front, i.e. the light-receiving, surface.
  • the tabs are thus soldered such that the front surface of one solar cell is connected to the back surface of the adjacent solar cell. This results in obscuration of a portion of the light-receiving surface of the solar cells, thus reducing the amount of current generated by the PV module.
  • the tabs are connected alternately between the front and back surfaces of the individual solar cells, a non-negligible spacing between the solar cells are needed to accommodate the tabs, reducing the packing density of the solar cells within the module.
  • the solar cells may incorporate a carrier collecting region on the light- receiving surface, in combination with methods to pass current through or around the substrate to a connection area on the back surface.
  • Current can be passed from a collection grid on the light-receiving surface to the back surface around the edges of the solar cell by incorporation of metallized regions on one or several sides of the cells, often referred to as metallization wrap around (MWA), (see B.T. Cavicchi et al., "Large area wrap around cell development", Proc. 16 th European PVSEC, 1984; W. Joos et al., "Back contact buried contact solar cells with metallization wrap around electrodes", Proc. 28 th IEEE PVSC, 2000).
  • MWA metallization wrap around
  • current can be passed to the back surface through metallized holes (or vias) through the substrate, often referred to as metallization wrap through (MWT) when a current collection grid is present on the light-receiving surface, or emitter wrap through (EWT) when no such collection grid is present,
  • MTT metallization wrap through
  • EWT emitter wrap through
  • connection to the front side grid is in this method achieved by small pins attached to the interconnection media, extending through holes in the individual solar cells. This requires very precise alignment of each solar cell, and may thus complicate the assembly process. To the extent necessary, the teachings of the above-mentioned paper and the above two mentioned patents are incorporated herein by reference thereto.
  • E. Van Kerschaver describes interconnection of individual back-contacted solar cells, where one polarity terminal is connected to a current collecting grid on the light-receiving surface through holes in the substrate, and where the two polarity terminals are accessible at the back surface as two separate and individually insulated regions.
  • Series connection of individual solar cells is then achieved by applying one wide conductive lead, covering both the one polarity terminal of one cell and the other polarity terminal of the adjacent cell.
  • Such interconnection poses strict requirements on the geometry of the contact regions at the back surface. Specifically, the two polarity regions must be accessible for contacting near opposite edges of the back surface.
  • each of the two polarity contact regions needs to be one continuous area, excluding the possibility of contacting solar cells where one of the polarity terminals is accessible as contact points or islands.
  • teachings of that document are incorporated herein by reference thereto.
  • the claimed invention aims to overcome the limitations of the above techniques, by allowing interconnection of back contacted solar cells where both polarity terminals are accessible at the same surface. Specifically, the claimed invention allows such interconnection where one or both of the two polarity terminals are accessible as isolated regions or contact points, without short circuiting the cells, thus not posing particular limitations to the geometrical arrangement of the contacting terminals.
  • the present invention relates to a method for interconnecting solar cells, where each solar cell having first and second polarity terminals accessible at the same surface, comprising connecting conductors between the first polarity terminal(s) of a first solar cell and the second polarity terminal(s) of a second solar cell, wherein the conductors connected to the first polarity terminal of the first solar cell is electrically insulated from the second polarity terminal(s) of the same solar cell by an insulation layer.
  • the present invention also relates to a solar cell device comprising interconnected solar cells, where each solar cell comprises first and second polarity terminals accessible at the same surface, where conductors are connected between the first polarity terminal(s) of a first solar cell and the second polarity terminal(s) of a second solar cell and where the conductors connected to the first polarity terminal of the first solar cell is electrically insulated from the second polarity terminal(s) of the same solar cell by an insulation layer.
  • the present invention achieves a simplified assembly of photovoltaic modules consisting of back-contacted solar cells.
  • the invention allows such back- contacted solar cells to be interconnected using existing manufacturing techniques, thus reducing the investment costs and easing implementation of the invention.
  • Modules manufactured using the methods according to the present invention exhibit increased current generation compared to prior art, and simplified processing compared to other techniques of interconnecting back-contacted solar cells.
  • FIG. 1-a is an illustration of interconnection of individual cells.
  • FIG. 1-b is an illustration of an alternative embodiment of fig. 1-a, in which alternate cells do not need to be rotated.
  • FIG. 1-c illustrates the interconnection conductors with insulation material.
  • FIG. 2-a illustrates one embodiment where an insulation material covers the conductors to be used for interconnection of the individual solar cells.
  • FIG. 2-b illustrates another embodiment where insulation layers in the form of precut sheet is placed on each of the individual solar cells in a suitable geometry.
  • individual solar cells are assumed to be interconnected in a series fashion, i.e. by electrically connecting a first polarity terminal region(s) of a first solar cell to a second polarity terminal region(s) of a second solar cell, both polarity terminal region(s) being accessible at the back side surface of the individual solar cells.
  • the assumption of such interconnection in a series fashion is only intended as one possible interconnection scheme, and the claimed invention is equally suitable for interconnecting such back contacted solar cells by electrically connecting the first polarity terminal of the first solar cell to the same polarity terminal of the second solar cell, i.e. in a parallel interconnection of individual solar cells.

  • the individual solar cells 1 are preferably aligned in such a fashion that one or more of the first polarity terminal regions 3 of the first solar cell and one or more of the second polarity terminal regions 4 of an adjacent solar cell lies along the same axis in the plane of the surface 2 at which the terminals 3 and 4 are accessible.
  • One or more of the first polarity terminal regions 3 of the first solar cell is then electrically connected to one or more of the second polarity terminal regions 4 of an adjacent solar cell by conductors 5.
  • an insulation material (not shown in the FIG. 1-a) is provided underlying the conductors' 5.
  • Methods to achieve electrical contact between the conductors 5 and the different polarity terminal regions 3 and 4 of the adjacent solar cells 1 include, but are not limited to, hot air soldering, infrared light soldering, local heat probe soldering, and ultrasonic bonding.

  • FIG. 2-a illustrates one embodiment of the claimed invention, in which such electrical insulation is achieved by an insulating material 6 covering the electrical conductor 5 prior to interconnection.
