Technology

Eight19’s innovative solar cell technology is based on printable organic semiconductor materials. Organic photovoltaics (OPVs) offer significant advantages over devices based on inorganic materials such as silicon.

OPV technology differentiators are as follows:

  • Superior low light performance
  • Flexibility
  • Non-toxic
  • Light weight
  • Pleasing aesthetics
  • Robustness

Plastic solar cell modules can be produced from solution under ambient conditions using existing, highly efficient and continuous roll-to-roll printing and coating processes. The result is ultra-thin, flexible solar modules that can readily scale up to very large volume manufacture.

Free of toxic compounds and with much less energy required to make the product (‘embedded energy’) compared with conventional approaches, Eight 19 modules are appropriate for deployment in indoor and off-grid applications.

Plastic Solar Cell Cross Section

Organic semiconductors originate from abundant, potentially low cost polymer materials. Their absorption spectrum can be tailored to suit artificial light sources as well as sunlight. The resulting devices operate efficiently in bright light as well as at very low light, and are well suited to applications ranging from energy harvesting indoors to off-grid power generation.

Eight19’s scalable production technology for printed plastic solar modules includes the development of solar cell and module architectures and scalable roll-to-roll production methods.  Based on technology originally developed by the Cavendish Laboratory at the University of Cambridge, Eight19’s experienced technical team has designed and optimised a versatile roll-to-roll coating plant capable of producing up to
200,000 m2/year of OPV.

 

Benefit Technology
Flexible, Robust, Lightweight Processing thin films on lightweight flexible substrates reduces material usage and enables more innovative ways of deploying the resultant modules for new and established markets. Our flexible, glass-free modules can withstand over 1000 bend cycles without degradation.
Excellent low light performance Indoor light is an ideal source of power. Organic materials have been developed that produce optimum power conversion efficiency from the spectrum of incandescent as well as fluorescent and LED lights used in modern commercial and residential environments.
New Capabilities Organic Photovoltaic (OPV) materials used in plastic solar cells are synthesised using standard organic chemistry techniques, and the properties of the photoactive materials across the light spectrum can be tuned to optimise performance. Contact us for the latest performance data.
Non-Toxic The non-toxic nature of plastic solar cells is important for widespread acceptance, product end-of-life and enables OPV modules to be more easily deployed.
Customised Appearance and Design The flexible, semi-transparent nature of plastic solar cells opens up attractive and innovative design possibilities. The modules’ finish can be customised to conceal the photovoltaic structure and increase customer appeal.
Reduced Balance of System Costs The use of mechanically robust, flexible plastic films can dramatically reduce the cost of housing and mounting the solar cells, enabling solar technology to be more easily and economically deployed.
Scaleable Module Production Organic semiconductor materials can be processed from solution at ambient temperatures onto low cost flexible substrates. This allows manufacturing on continuous webs (roll-to-roll), resulting in rapid scalability at low capital outlay.
