Raynergy Tek sets new world record in power conversion efficiency for solution-processed single junction organic photovoltaic (OPV) cells. The 13.28% efficiency was independently confirmed by Newport PV laboratory, a recognized center for verification of solar cell results under standard testing conditions in August 2018. The certified device measurement results has been submitted to US National Renewable Energy Laboratory (NREL) for review for possible recording into NREL Efficiency Chart.
The exciting breakthrough was made possible by the Raynergy R&D team on their third generation proprietary PV organic ink, known as NF series and consists of proprietary high bandgap polymer donor and low bandgap Non Fullerene Acceptor.
"We are exceptionally thrilled to be the first to demonstrate Non-Fullerene OPV single junction system to record PCE above 13% under Quasi Steady State (QSS) measurement. The Non fullerene system has gained much attention beginning 2018 with constant positive news on setting world record PCE by many renowned research group. However, the NF OPV device's electrical stability under continuous 1 sun light measurement was quite a challenge. Our R&D team sets focus on the novel molecular design on the both P and N type to achieve the relatively stable NF devices. Moreover, the novel ink is sky blue in color which we could now offer new color to our customers," commented by Dr. Phoebe Tan, Raynergy's CEO.
The novel materials effort was led by Director of the R&D novel materials, Dr. Chuang-Yi Liao, "Our team started designing the Non Fullerene System a year ago, we believe the Non-Fullerene system is a good strategy to enhance efficiency of OPV product without compromising the stability, which possibly outcome with real world applications. Together with my Acceptor Project team leader, Dr. Chia-Hao Lee, our molecular design approach for both P and N products takes into account on achieving good solubility in non-chlorinated solvents as well as scalability in materials synthesis. In fact, the scale up is now underway."
Raynergy CTO, Dr. Yi-Ming Chang commented, "The newly certified NF device results is based on inverted device architecture, which is commonly used by OPV module makers. Also, the air processability of the NF ink was tested and shown that coating and baking in ambient could achieved acceptable results with minute loss in PCE, we believe the ink should be compatible with existing coating and manufacturing processes and may enable the fabrication of highly efficient OPVs. The only challenge remains in the Non Fullerene OPVs is the search of suitable solution processed hole transporting layer, which will be our current intense focus."
The remarkable progress of OPV efficiency over the past 2 years based on Non Fullerene system has no doubt opened up new avenue for OPV technology to further propel to possible commercialization in the near future. "Our corporate priority remains to provide high performance OPV materials system at acceptable cost to our business partners, hence the scaling up process development for NF3000 is our top priority now. And we will continue to strive to adhere to our corporate's target which is to increase efficiency by 1% each year. So far, we are on track and we hope to reach certified 14% Single junction OPV by early next year." stated by Jason Hsiao, Chairman of Raynergy.
