A large array of solar panels is seen reflecting a partly cloudy sky. The panels stretch across the image, capturing a mix of blue sky and white clouds. Vegetation is visible between the panels.

Thin film solar modules

Thin film solar modules are an established and cost-effective solution, especially for utility scale ground-mounted systems and building integrated solar elements

The energy market is a highly competitive environment, and we understand the need for continuous product and process improvements. We therefore offer you a ready-to-use core assortment as well as customized adhesive solutions for your specific requirements. Take advantage of our extensive experience to enhance your production and to develop new modules!

CHARGE COLLECTION

Charge collection

A close-up of a sheet with thin, parallel, white lines on a dark surface. A strip of red tesa tape is partially peeled back from the sheet, revealing the light blue background underneath. The sheet and tesa tape are arranged at an angle.

Our self-adhesive charge collection tape is a fast and reliable method to electrically interconnect thin film solar cells. For rigid or flexible panels and all common cell technologies.

tesa® 60860 – Self-adhesive charge collection tape

  • Tin-plated copper backing with electrically conductive adhesive (ECA)
  • ​High durability, low electrical resistance
  • Available in roll format for automated application
LEAD FOIL INSULATION

Lead foil insulation

A long gray rectangular object is positioned above a bright red rectangle, both situated over a vertically-striped gray and blue surface. The background is a light blue, suggesting a sky or open space.

Self-adhesive PET tapes are the ideal choice for lead foil bonding and insulation, especially when running across the cells. 

tesa® 4972 - Double-sided PET tape

  • Thin product design with high dielectrical strength
  • ​Durable, high quality adhesive system
  • Enables a trouble-free application process
RIBBON BLACKOUT

Ribbon blackout

A close-up of a gray flat surface with a grid pattern, featuring a strip of red tesa tape being peeled away. The surface is shown at an angle, with a blue background.

Black single-coated PET tape to permanently cover metal ribbons for aesthetic or electrical insulations purposes on the side of the module that receives sunlight.

tesa® 7250 – Single-sided black PET tape

  • Thin and flexible design
  • UV and temperature resistant​
BACK RAIL FIXATION

Back rail bonding and fixation

Close-up of a solar panel with a textured surface. Red markings and lines are visible on the panel, along with a raised section of glass secured with tesa tape. The panel is set against a light blue background.

Back rails are used for PV power plants as part of the mounting system. They are bonded to the reverse side of the module using adhesive tape or liquid adhesive. Our adhesive tapes offer a fast application process and can be used as firm spacers in combination with liquid adhesives or as a full bonding solution. 

tesa® ACXplus 7078 - Acrylic foam tape

  • High immediate adhesion without curing time
  • Stress dissipation properties
  • High bonding strength and highly durable
CABLE FIXATION

Cable fixation

A black cable with a connector is wrapped in a red protective sheath, lying on a metallic, grooved surface. The grooves in the surface run parallel to the cable. The background is a light sky blue.

Our single-sided tapes are ideal for securing photovoltaic cables safely during shipment and installation.

tesa® 64283 single-sided strapping tape

  • Efficient tape application process
  • ​High immediate adhesion on a wide range of substrates
  • Easy removal after oversea container shipment 
HOLE COVERING

Hole covering during lamination

A red, curved object is partially rolled onto a horizontal, gray-striped surface with a narrow strip of tesa tape intersecting the stripes. The background is a light blue area at the top edge of the image.

For masking holes in the backsheet during the lamination process, our single coated products offer high temperature resistance and great removability.

tesa® 50600 PET tape with silicone adhesive

  • Bonds to almost all types of back sheets
  • ​220 °C temperature resistance
  • Excellent removability after lamination
JUNCTION BOX FIXATION

Junction box fixation

Close-up of a black sensor device positioned on a surface with parallel lines. A connected cable extends from the sensor, and a red, square-shaped line is highlighted on the surface beneath it, marked with tesa tape. The background is light blue.

For temporary bonding of the junction box in combination with liquid adhesives. In addition to the spacer function, our adhesive tapes provide fast initial bonding and help implement a reliable and efficient production process.

tesa® 62510 - Double-sided PE foam tape

  • 1 mm total thickness
  • ​High immediate bonding strength
  • Good dispensing and die-cutting properties
