opv-layersMaterials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. These inorganic components are getting rare on earth and expensive and need to be replaced. As a consequence the newest generation of solar panels are made from widely spread organic materials. They are flexible, lightweight and inexpensive.

The benefits of organic photovoltaics are:

  • Renewable energy
  • Low CO2 footprint
  • Highly automated
  • Low energy consuming
  • Cost effective roll-to-roll production through printing
  • Novel form factor

The opportunities (in economic terms) are:

  • Cell architecture of organic photovoltaicExpand the innovation base in alternative energies
  • Develop manufacturing technologies: high level of automation, highly trained personnel, low energy consumption and close proximity to suppliers and markets

The challenges are:

  • Efficiency
  • Lifetime
  • Costs


OPV LayersThe SUNFLOWER partners will make an effort in high-tech research with the goal to produce printed organic photovoltaic panels with high efficiency architectures such as tandem cells and dedicated light management structures. The performance of the photo active and passive barrier materials will become much higher including process controlled morphology. They will deliver solutions for cost effective flexible substrates, diffusion barriers and conductors. In the near future a deeper understanding of the device physics, an elucidation of degradation mechanisms and an estimate of the environmental impact of the main materials and processes will be available thanks to the SUNFLOWER partners.

 

 

 

 

The requirements for our prototype:

  • High module efficiency to be competitive with other photovoltaic (PV) technologies
  • Multilayer structure (“tandem”) to achieve high efficiency
  • Cost effective barriers and getters to achieve long lifetime
  • Roll-to-roll atmospheric printing processes to lower costs [where costs include fabrication (Eur) and environmental impact (kgCO2)]
In order to obtain electricity from solar radiation, one needs a pannel with cells from a material or substance that converts light energy into electrical energy. Further semicunductors are needed to store or control the energy. Materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. These inorganic components are getting rare on earth and expensive and need to be raplaced.
As a consequence the newest generation of solar panels are made from widely spread organic materials. They are flexible, lightweight and inexpensive.
