First Solar, Inc. (Tempe, Arizona) has issued its 2022 Sustainability Report highlighting its continued, industry-leading environmental, social, and governance (ESG) progress. The only US-headquartered company among the world’s ten largest solar manufacturers, First Solar’s photovoltaic (PV) solar modules are reported to have the lowest carbon and water footprint and fastest energy payback time of any commercially available PV technology today.
ASCA, an organic photovoltaics (OPV) global leader and part of the French ARMOR Group, has purchased the most relevant device- and module-related intellectual property (IP) portfolio regarding printed OPV. At the end of 2021, ASCA took patents on OPV production and technology from the Darmstadt, Germany-based leading science and technology company Merck. With this purchase, the company has become the largest portfolio owner with regard to printed OPV worldwide through tripling its number of patents.
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.
