Grenzebach manages the entire process of fully automating solar production plants – from factory simulation to installation and commissioning. The company’s expertise lies in the highly precise and gentle treatment of sensitive substrates. This concept also applies to fully automated solutions for the mirrors used in solar-thermal power plants (CSP) and concentrator module manufacturing (CPV). Grenzebach specialises in applications featuring precise and delicate joining with ac-curacies down to 20 µm, contact-free handling and advanced inspection systems. ISO 5 clean environment, SEMI and UL are standard at Grenzebach. Worldwide, more than 40 Grenzebach thin-film lines have been installed for CIGS and CdTe technologies. The portfolio ranges from conveyance and buffering technology to in-house developed MES systems.

Front end

The front end of the line produces the substrate. In addition to tracking the substrate ID, the temperature and cleanroom parameters are monitored. The state-of-the-art inspection systems ensure a high-quality standard. Storage systems for interim buffering at the coating and structuring processes in-crease the overall throughput through the front end.

Back end

In the back end of line, the module is produced from the individual substrates. Laser edge deletion, film unwinding, pairing, film trimming, and J-Box installation are key processes of the back end. Tailored back rail applications, as well as packaging and warehouse systems, complete the back-end product range.

To support the high-volume production of any of the present thin-film PV technologies Grenzebach supplies large area sputter deposition tools. The main targeted product technologies are back- and front contact coatings including various metal, transparent conductive oxides (TCO – e.g. AZO, ITO, GZO) and absorber layers for e.g. CIGS and CdTe manufacturing lines. All deposition tools employ PVD coating technologies (physical vapour deposition) and are tailored according to  customer needs. The combination of a tailor-made solution based on industrial proven high-volume production tools assures utmost high yield and quality of the coating line.

Company History

Grenzebach Maschinenbau GmbH was founded in 1920 as a family-owned agricultural machine repair shop located in the small village of Hamlar, Germany.  In the 1970s, Grenzebach developed the world’s first processing systems to fully automate the float glass production process and went on to become the world’s leading production line automation specialist. Today, Grenzebach is a global company with 1,500 employees and seven production lines across three continents.

Oxford PV is based in Oxford (UK) and near Berlin (Germany) and is the pioneer and technology leader in the field of perovskite solar cells.

Commercial size perovskite-silicon solar cell

The company is commercialising perovskite-silicon tandem solar cells. This technology can be built into standard PV modules and generates significantly more energy with a lower cost, than conventional silicon PV. 

Oxford PV is building a volume production line at the company’s factory in Germany. The production line equipment is being supplied by Meyer Burger – a leading photovoltaic equipment supplier. 

Oxford PV’s first commercial product is expected in the market mid-2021.

Company history

Oxford PV was established in 2010 as a spin-out from Professor Henry Snaith’s lab at the University of Oxford. 

In 2014, the company's focus moved to perovskite-silicon tandem solar cell research, and in 2017, the first industry-sized perovskite-silicon tandem solar cell was produced. 

Today, Oxford PV has the largest team globally, exclusively focused on developing and commercialising a perovskite-based solar cell technology, with over 300 related patents. 

Investors include Equinor, Legal & General Capital, Goldwind, and Meyer Burger.

Oxford PV’s perovskite-silicon tandem solar cell technology has achieved a certified efficiency of 28%, and its efficiency roadmap extends to the mid-30s.

Saule Technologies

Saule Technologies develops innovative solar cells based on perovskite materials. It has pioneered the use of ink-jet printing for the production of flexible, lightweight, ultrathin, and semi-transparent photovoltaic modules. The use of perovskite materials allows Saule Technologies to inkjet-print solar cells on basically any surface which can produce energy even when the exposure to light is limited.

Saule Technologies aims to make solar power accessible to everyone and believes it can achieve this by offering low-cost products on a global scale.


Saule Technologies was conceived in 2013, when a young PhD student at the University of Valencia in Spain, Olga Malinkiewicz, invented a unique method to produce solar cells by coating perovskites on flexible foils. Olga soon realised that her breakthrough could impact the world on a massive scale, but that she couldn’t do it alone. Luckily, she met Piotr Krych and Artur Kupczunas and together, they officially started Saule Technologies.


Since then, Saule Technologies has continued to develop perovskite applications. In 2016, it created the first real-life application of perovskite solar cells - a mobile phone charger that operates under artificial light. This was closely followed by further innovations such as an A4, flexible, perovskite solar module inkjet printed on an ultrathin plastic foil, and an A4 semi-transparent perovskite module. These developments allowed Saule to sign industrial contracts with big players - such as Skanska and Ergis - and initiate product development. In a short period of time, the efficiency of solar modules improved beyond 10 %, and the first BIPV demonstrator was installed already by the end of 2018. In 2019, the main focus was on developing the first ever production line in the world that is capable of ink-jet printing perovskite solar modules – up to an area of 1 m2.  In 2020, Saule is planning to release the first industrial sized modules aiming at IoT applications.z

Von Ardenne

Von Ardenne is an industry-leading coating equipment manufacturer based in Dresden, Germany. The company supplies highly productive inline coaters in all customary sizes for TCO layers, backside contacts and semiconductor layers based on CIS or CdTe. VON ARDENNE’s high-speed coating and deposition equipment has played a crucial role in enabling the thin-film PV industry to grow rapidly.  VON ARDENNE’s magnetron sputtering technology enables the even and precise deposition of semiconductor materials onto sheets of glass or other large-area substrates and ensures both a high manufacturing throughput at optimised costs and consistently high quality.

Von Ardenne’s magnetron sputtering technology “sputters” the coating material (known as the target) by bombarding it with positive gas ions in a medium vacuum. The coating material particles evenly condense onto the substrate as a continuous thin-film.
