10 2 Power Conversion Efficiency polymer tandem solar cells consisting of two identical sub cells
Advanced Materials, 2013Co-Authors: Jingbi You, Chun-chao Chen, Ken Yoshimura, Jing Gao, Kenichiro Ohya, Ziruo Hong, Yang YangAbstract:Polymer tandem solar cells with 10.2% Power Conversion Efficiency are demonstrated via stacking two PDTP-DFBT:PC₇₁ BM bulk heterojunctions, connected by MoO₃/PEDOT:PSS/ZnO as an interconnecting layer. The tandem solar cells increase the Power Conversion Efficiency of the PDTP-DFBT:PC₇₁ BM system from 8.1% to 10.2%, successfully demonstrating polymer tandem solar cells with identical sub-cells of double-digit Efficiency.

A polymer tandem solar cell with 10.6% Power Conversion Efficiency
Nature Communications, 2013Co-Authors: Jingbi You, Letian Dou, Ken Ohya, Chun-chao Chen, Tom Moriarty, Ken Yoshimura, Keith Emery, Jing Gao, T Kato, Gang LiAbstract:An effective way to improve polymer solar cell Efficiency is to use a tandem structure, as a broader part of the spectrum of solar radiation is used and the thermalization loss of photon energy is minimized. In the past, the lack of high-performance low-bandgap polymers was the major limiting factor for achieving high-performance tandem solar cell. Here we report the development of a high-performance low bandgap polymer (bandgap 60% and spectral response that extends to 900 nm, with a Power Conversion Efficiency of 7.9%. The polymer enables a solution processed tandem solar cell with certified 10.6% Power Conversion Efficiency under standard reporting conditions (25 °C, 1,000 Wm(-2), IEC 60904-3 global), which is the first certified polymer solar cell Efficiency over 10%.

solution processed small molecule solar cells breaking the 10 Power Conversion Efficiency
Scientific Reports, 2013Co-Authors: Yongsheng Liu, Chun-chao Chen, Jing Gao, Ziruo Hong, Yang Yang, Huanping Zhou, Letian DouAbstract:A two-dimensional conjugated small molecule (SMPV1) was designed and synthesized for high performance solution-processed organic solar cells. This study explores the photovoltaic properties of this molecule as a donor, with a fullerene derivative as an acceptor, using solution processing in single junction and double junction tandem solar cells. The single junction solar cells based on SMPV1 exhibited a certified Power Conversion Efficiency of 8.02% under AM 1.5 G irradiation (100 mW cm−2). A homo-tandem solar cell based on SMPV1 was constructed with a novel interlayer (or tunnel junction) consisting of bilayer conjugated polyelectrolyte, demonstrating an unprecedented PCE of 10.1%. These results strongly suggest solution-processed small molecular materials are excellent candidates for organic solar cells.

Advanced Materials, 2015Co-Authors: Vinay Gupta, Vishal Bharti, Mahesh Kumar, Suresh ChandAbstract:: Optically resonant donor polymers can exploit a wider range of the solar spectrum effectively without a complicated tandem design in an organic solar cell. Ultrafast Forster resonance energy transfer (FRET) in a polymer-polymer system that significantly improves the Power Conversion Efficiency in bulk heterojunction polymer solar cells from 6.8% to 8.9% is demonstrated, thus paving the way to achieving 15% efficient solar cells.
