Photovoltaic cell electrode adhesive

What is a self-adhesive laminate solar-cell electrode?

A self-adhesive laminate solar-cell electrode is presented based on a metal grid embedded in a polymer film ( x – y conduction) and set in contact with the active layer using a pressure-sensitive adhesive containing a very low quantity (1.8%) of organic conductor, which self-organizes to provide z conduction to the grid.

Can a polymer replace a silver-based electrically conductive adhesive?

Here, we use poly (3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), a conducting conjugated polymer, as an intrinsically conductive adhesive (ICA) to replace silver-based electrically conductive adhesives (ECAs) as the adhesive interconnect for shingled solar modules.

How do solar cells bond?

The bonding process uses an electrically conductive adhesive (ECA) to connect the cell strips together. The shingled strings are interconnected through a metal ribbon to fabricate a high power and high density photovoltaic module. Therefore, the solar cell should exhibit the electrode structure suitable for dividing and bonding.

Can a solar cell have a divided electrode structure?

Fabrication of solar cells with a divided electrode structure A screen printing process was used for metallization, and a 6-inch multicrystalline blue wafer without electrodes was used. A multicrystalline silicon solar cell with an electrode pattern for division was fabricated to verify the simulation results.

Can self-adhesive laminate electrodes scale up flexible lightweight PV applications?

Here we describe a major breakthrough which allows a highly conducting self-adhesive laminate electrode to be applied to devices at room temperature which could be applied to scale up flexible lightweight PV applications.

How are shingled Solar Cells fabricated?

Shingled cells were fabricated from Sunpreme SHJ solar cells using PEDOT:PSS-based ICAs and silver-based ECAs (Figures 2 A and S5–S7). We note that all interconnected cells described here are unlaminated and unencapsulated.
