X10D - Efficient, low-cost, stable tandem organic devices
New designs, materials and manufacturing technologies for market-competitive organic photovoltaic modules
X10D aims to enable organic photovoltaics (OPV) to enter the competitive thin-film PV market. It will achieve this by pooling the knowledge and expertise of the leading research institutes and start-up companies in Europe, and is the first project of its kind to leverage this knowledge irrespective of the processing technology. It will use the strengths available in device efficiency and architectures in both solution processed as well as small molecule based OPV.
The objective for X10D is to develop efficient, low-cost, stable tandem organic solar cells by applying new designs, materials and manufacturing technologies to create market-competitive OPV modules. Therefore, X10D proposes to bring together partners that compose a complete and unique OPV research and development consortium, from academic partners, research centers, SMEs, and large companies. Together, the X10D partners cover each segment of the complete value chain: materials development and up scaling, device development and up scaling, large area deposition equipment and processes, novel transparent conductors, laser scribing equipment and processes, encapsulation technologies, energy, life-cycle, and cost analysis and finally end-users. The main objectives for X10D can be quantified more explicitly as:
- To increase the power conversion efficiency to achieve at least a 12% on cell level (1 cm²), and 9% on module level (100 cm²)
- To guarantee a minimum of 20 years life for OPV modules on glass, and 10 years on foil
- To decrease the cost under 0.70 €/Watt-peak
Dresden, March 24, 2014 – Heliatek GmbH, worldleading company in the production of organic solar film, has reached a new record in the efficiency of transparent solar cells. The latest development allows transparency levels up to 40% with an efficiency of over 7%. The company already holds the world record of 12% cell efficiency for opaque (non-transparent) organic solar cells.
In this week’s Nature Communications imec presents the development of fullerene-free organic photovoltaic (OPV) multilayer stacks achieving a record conversion efficiency of 8.4 percent. This breakthrough achievement is an important step to bring organic photovoltaic cells to a higher level in the competitive thin-film photovoltaics marketplace.
