Characteristics

Organic Photovoltaic Film Born of Beautiful Light Project©: ASCA© 1.0

Good to Know

Beautiful Light Project© intends to shape our daily lives by making the most of the very properties, which light, a source of natural energy, offers. Shaping the practices of billions of people means radically breaking with market norms. As soon as 2016, the new criteria for specific OPV technology characteristics (Organic Photovoltaic film) will set those market norms.

An OPV cell is made up of 5 layers (without encapsulation):

Harvesting Energy vs. Power or Instant Output

Currently, two criteria are used to measure a photovoltaic panel’s performance: instant power (expressed in Wp/Watt-peak) or instant output (expressed in %) under 1000W/m2 exposure.

While this data is suitable when producing electricity that is re-injected into the main network, disconnecting an object from the network and making it self-sufficient will not be enough, whatever the season or period of the year. Consequently, we clearly consider the real determining variable to be the quantity of energy recovered daily or weekly under various conditions of exposure.
The quantity of harvested energy will vary according to the suggested OPV module size  (in width and length) or a combination of several modules (mounted in series or in parallel).
The intrinsic characteristics of the OPV (capacity to produce energy under low light conditions or weak temperature conditions) will allow photovoltaic solutions to be proportioned optimally (battery included).

Lifetime

An OPV module’s lifetime depends on several factors: conditions of use (outdoor and indoor), quality of barrier films or its integration in final product. Lifetime is calculated on the basis of optimal results. Beyond the indicated lifetime, the OPV module continues to operate with a decreasing linear performance.

Flexibility

Flexibility is the marking point that separates OPV technology from other photovoltaic technologies. Curved products do not present a limit anymore. Flexibility is expressed optimally in strip length (see diagram). The OPV module (Organic Photovoltaic film) also offers more moderate flexibility in strip width.

Lightness

Lightness is also a feature that distinguishes OPV technology (Organic Photovoltaic film) from other photovoltaic technologies. While existing photovoltaic panels require a frame to secure the mount, the OPV module is so light, it can generally integrate itself onto any object without prior reinforcement.

Transmission of light

An OPV module’s efficiency (Organic Photovoltaic) is directly related to the quantity of absorbed light. The bigger the quantity, the weaker the “transparency effect”. Inversely, the more light the module allows to pass, the stronger the “transparency effect”.
As available energy in invisible wavelengths (infra-reds, ultra-violets) is not sufficient to offset available energy in what is visible, the challenge is in determining the right balance between the aimed application and the required needs for autonomy.
