ASCA® industrial expertise
ARMOR enjoys a worldwide reputation for its expertise in the formulation and coating of inks onto thin films. Exploiting our industrial expertise to produce this latest generation of ASCA® photovoltaic innovation is the driving force behind our success.
The ASCA® film is composed of selected eco-friendly materials
The materials selected by ARMOR have led to the development of formulations without equal anywhere in the world, designed with the support of a network of strategic partners.
ARMOR has decided to develop its own formulations in order to work with soluble polymers & non-toxic raw materials. Compatible solvents free of chlorofluorocarbons (CFCs) have been favoured over other components traditionally used in such products.
Combined with the development of specific industrial processes and equipment, these solutions enable optimisation of layer thickness, guaranteeing improved performance while minimising the consumption of materials.
The ASCA® film, a fast and high-performance manufacturing process
ASCA® photovoltaic films are produced using a roll-to-roll coating process. This process offers the advantage of incredible production speed (up to 600 metres per minute for thermal transfer ribbons, compared to 10 metres per minute for other roll-to-roll processes via evaporation). This method also offers a very high level of adaptability in terms of sizing.
The production of photovoltaic film is characterised by the successive coating of different layers, 7 in total:
5 functional layers composed of:
One layer of photoactive polymers at the heart of the structure.
Two other intermediate layers around the active layer, one above and one below.
Electrodes are placed around the layers: one in the upper section and the other in the lower section to aid in electron transport.
Two layers of plastic barrier film are then over-laminated to encapsulate the functional layers and protect them from external attack, such as from:
- UV light
- Mechanical degradation
This protection optimises the lifetime stability of the ASCA® film. It is on these protective layers that supplementary functionalities can be added, such as anti-scratch, anti-scuff and mat visual effects.
How are the performance levels of ASCA® measured?
Using solar simulators and automated multimeters, ARMOR measures the power generated by the ASCA® photovoltaic films. This fine-tuned measurement equipment is used to:
Measure the performance of the photovoltaic modules and extract the electrical parameters (power, voltage, power, resistance).
Guarantee the absence of defects in every cell via a specific mapping process.
To optimize the lifetime stability of the ASCA® film, the behaviour of the photovoltaic modules is analysed under conditions that are as real-life as possible via external exposure testing. These analyses are also conducted in climatic chambers to create specific levels of temperature, humidity and luminosity.
The ASCA® film useful life
To optimize the lifetime stability of the ASCA® film, the behaviour of photovoltaics modules has been examined in closest conditions of reality thanks to an outdoor testing bed. These studies are also carried out in climatic chambers allowing to establish specifics temperature levels, humidity and brightness rates.
