Solar screen printing
Screen printing is an alternative manufacturing method for manufacturing contact structures of solar cells and has been proven to be highly productive, cost-effective and scalable.
Solar energy ion implantation
Ion implantation is a technology borrowed from the semiconductor industry, which enables solar cell manufacturers to simplify their processes, manufacture high-efficiency batteries and reduce the cost per watt.

Our unique ion implantation technology can produce more efficient solar cells through precise PN Junction Engineering. Compared with diffusion, the ion implantation junction has superior emitter junction quality and uniformity, so it has higher yield.
Solar cell manufacturing
Improving battery efficiency is the key lever to reduce the cost per watt of solar energy. As conventional batteries approach their maximum possible efficiency, battery manufacturers must adopt new, advanced battery structures to ensure significant efficiency gains.
Solar wafer inspection
Progress in wafer and inspection technology is critical to meeting the cost targets of the solar industry, as silicon and wafers account for more than half of the total cost of the entire module.
Metal and oxide barrier films

HCVAC vacuum provides a wide range of equipment combinations for the mass-produced flexible barrier market, which can be used for packaging and other applications, in which metal, oxide or transparent barrier layers are deposited on flexible substrates in vacuum by the roll to roll process. These processes include evaporation through electrically heated ceramic vessels, induction heated crucibles, and electron beam evaporation or sputtering deposition.

Color change and holographic film

Evaporative electron beams (EBS) are required for various applications in the secure market when special layers and precision coatings are required to protect the authenticity of brands and products, as well as currencies and certificates. The solution can deposit special coatings of precision coatings, such as optical quality dielectric materials, to support the security and anti-counterfeiting applications of holography (preprint substrate). Today, there are a variety of device solutions available for deposition on flexible substrates.

In situ patterned metal layer

Online printing (in situ) roll to roll system prints grayscale and patterned structures on a variety of substrates, including polyethylene terephthalate (PET), polyethylene (PE), oriented polypropylene (OPP), cast polypropylene (CPP) paper and paper as alternative solutions for off-line demetallization processes - eliminating process steps in the production of differentiated packaging

Multilayer depositional system

For touch panel display of mobile electronic devices, transparent conductive oxide (TCO) is sputtered and deposited on hard coated PET. In order to match the reflective appearance of the sputtered ITO region with the etched free area of the uncoated substrate, the "refractive index matching" stack of high and low refractive index dielectrics is reactive sputtered onto the substrate. For sputtered window coatings for automotive glass applications, multilayer stacking of oxides and metals reduces the heat load from the sun.
