The single-junction OPV hits new world efficiency record over 15%
A team led by Prof. Yingping Zou form College of Chemistry and Chemical Engineering, Central South University, has designed and synthesized a new class of non-fullerene acceptor, Y6, that employs an electron-deficient-core-based central fused ring with a benzothiadiazole core, to match with commercially available polymer PM6. The team cooperated with Prof. Yongfang Li from Institute of Chemistry, Chinese Academy of Sciences, and Prof. Yong Cao as well as Prof. Hin-Lap Yip, from Institute of Polymer Optoelectronic Materials and Devices, State Key Laboratory of Luminescent Materials and Devices, South China University of Technology. They developed highly efficient OPVs made from Y6 in conventional and inverted architectures each exhibited a high efficiency of 15.7%, measured in two separate labs. Inverted device structures were certified at Enli Tech Laboratory demonstrated an efficiency of 14.9%.
This research, “Single-Junction Organic Solar Cell with over 15% Efficiency Using Fused-Ring Acceptor with Electron-Deficient Core.” was published in Joule. By this research, the team provides new insights into employing the electron-deficient-core-based central fused ring when designing new non-fullerene acceptors to realize improved photovoltaic performance in OPVs.
Enli Tech Lab owns the Third-Party Validation Authority
As the third-party certification, Enli Tech Lab conducts exact test methods and procedures to confirm that any kind of solar cells compile with all standard requirements. This allows customers to get the high stability, accuracy and accredited calibrations.
The testing of the sample was performed at Standard Testing Conditions (STC) in accordance with IEC 60904-1:2006 Photovoltaic devices – Part 1: Measurement of photovoltaic current-voltage characteristics and Test standard operation procedure of maximum power measurement of solar cells under the irradiation with a steady-state class AAA solar simulator according to IEC 6090-9:2007 Photovoltaic devices – Part 9: Solar simulator performance requirements. The spectral mismatch is calculated according to IEC 60904-7:2008 Photovoltaic devices – Part 7: Computation of the spectral mismatch correction for measurements of photovoltaic devices. The spectrum of the solar simulator is measured with a spectroradiometer. The spectral responsivity (or quantum efficiency) of the device under test is measured with gating monochromatic as well as two DSP lock-in amplifiers to instantaneously monitor the light intensity according to IEC 60904-8:2014 Photovoltaic devices – Part 8: Measurement of spectral responsivity of a photovoltaic (PV) device.
