Laserbox - Hermetic Encapsulation of Photovoltaics

Unique Selling Propositions

  • Laser-assisted hermetic encapsulation of solar cells
  • Sealing below 65 ºC under inert or dry atmosphere
  • Seals solo devices or modules with areas up to 30 x 30 cm2

Concept and Design

Developed at the Faculty Engineering of University of Porto, this method is efficiently used to encapsulate Perovskite Solar Cells and Dye-Sensitized Solar Cells in-between two glass substrates, protecting the devices from leakage and harm from moisture or air. The hermeticity complies with the Mil-Std-883H, delivering unprecedent long-term stability, which is critical for the industrialization of second and third generation photovoltaic cells.

Standard Specifications

  • solo devices up to 30 cm x 30 cm
  • multiple devices (up to 8) of smaller areas
  • modules (up to 8 strips)

When using one laser, sealing will be achieved down to 120 ºC; if we employ two lasers, the sealing can be done down to 65 ºC.

Dry Air, Nitrogen, Argon, or others

Two cameras, one a PTZ camera with high resolution and optical zoom to record sealing videos, and a 2D Machine Vision camera from SICK that enables pattern recognition.
