Manufacturing for photovoltaic cells, concentrating photovoltaic assembly and converter production benefits from the wide range of Nordson ASYMTEK's automated fluid dispensing systems

Nordson ASYMTEK's automated fluid dispensing systems are ideal for a range of applications for fuel cell manufacturing, photovoltaic cell production and assembly, and other products that support alternative energy equipment.

Photovoltaics - Via Filling for Interconnection

Via filling for interconnections between the front and back of photovoltaic (PV) cells can be achieved by using non-contact jet dispensing, which helps make the roll-to-roll process more efficient.

Many CIGS (Copper Indium Gallium Selenide) PV suppliers focus on applying roll-to-roll process to production for cost saving, while eliminating silicon consumption. And PV panels require interconnections between front and back sides to stack cell voltage. These interconnections are made through vias, which have insulation and conductive layers. PV suppliers may want to apply roll-to-roll to the interconnection process as well as to the CIGS deposition process.

Jet dispensing makes the roll-to-roll process more efficient by firing certain amount fluid to fast moving targets (vias) with distance. The fast dispensing and the wide range of fluids it can handle make jet dispensing the ideal choice. In addition, the fluid amounts can be closely controlled, using our unique software feature called, Calibrated Process Jetting or CPJ. Wide fluid capable range: UV curable, conductive ink and others.

Thermal Interface Material Dispensing

Nordson ASYMTEK's automated fluid dispensers and systems are ideal for the production and assembly of Concentrating Photovoltaic (CPV) cells. An important part of these cells are thermal interface materials (TIM) for cell heat dissipation. Nordson ASYMTEK offers a range of products to meet these needs. CPV cost competency against other PV technologies depends on efficiency of light concentrating with inexpensive optics. Precise optics assembly with tight tolerance adhesive dispensing, coating and sealing thus is required to make sure the cost advantage.

Nordson ASYMTEK's automated dispensing systems deliver fluids precisely within restricted assemblies with tight tolerances. Our patented Mass Flow Calibration - or MFC - ensures that dispensing is precise and with little waste.

Coating for Converter Box Assembly

Nordson ASYMTEK's automated fluid dispensers and coating systems are ideal for the production and assembly of converter boxes used in photovoltaic assemblies.
