By using new semiconductor materials, organic solar cell expert ASCA has increased the efficiency of its modules by 40 percent. The new components are supplied by the Taiwanese company Raynergy Tek. Raynergy Tek specialises in developing organic semiconductor materials for OPV modules, such as non-fullerene acceptors (NFAs). With an efficiency record of around 20 percent in laboratory cells, they promise significantly higher performance than conventional acceptors. ASCA has succeeded in integrating NFA-based materials into its prefabrication for the first time. Using materials supplied by Raynergy Tek, the company has been able to increase the efficiency of its semi-transparent free-form solar modules to around 70 watts per square metre.
