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, T. Kato, Jing Gao, 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%.

very high efficiency Solar Cell modules
Progress in Photovoltaics, 2009Co-Authors: Allen Barnett, Keith Emery, Douglas Kirkpatrick, Christiana Honsberg, Duncan T Moore, M W Wanlass, Richard G Schwartz, D E Carlson, Stuart Bowden, Dan AikenAbstract:The Very High Efficiency Solar Cell (VHESC) program is developing integrated optical system–PV modules for portable applications that operate at greater than 50% efficiency. We are integrating the optical design with the Solar Cell design, and have entered previously unoccupied design space. Our approach is driven by proven quantitative models for the Solar Cell design, the optical design, and the integration of these designs. Optical systems efficiency with an optical efficiency of 93% and Solar Cell device results under ideal dichroic splitting optics summing to 42·7 ± 2·5% are described.

plasmonic polymer tandem Solar Cell
ACS Nano, 2011Co-Authors: Jun Yang, Jingbi You, Chun-chao Chen, Ziruo Hong, Wanching Hsu, Hairen Tan, Xingwang Zhang, Yang YangAbstract:We demonstrated plasmonic effects in an inverted tandem polymer Solar Cell configuration by blending Au nanoparticles (NPs) into the interconnecting layer (ICL) that connects two subCells. Experimental results showed this plasmonic enhanced ICL improves both the top and bottom subCells' efficiency simultaneously by enhancing optical absorption. The presence of Au NPs did not cause electrical characteristics to degrade within the tandem Cell. As a result, a 20% improvement of power conversion efficiency has been attained by the light concentration of Au NPs via plasmonic near-field enhancement. The simulated near-field distribution and experimental Raman scattering investigation support our results of plasmonic induced enhancement in Solar Cell performance. Our finding shows a great potential of incorporating the plasmonic effect with conventional device structure in achieving highly efficient polymer Solar Cells.

tandem Solar Cell concept and practice in organic Solar Cells
2015Co-Authors: Ziruo Hong, Letian Dou, Yang YangAbstract:In the past decade, organic Solar Cell (OPV) technology has been intensively studied and improved significantly due to its attractive properties in manufacturability, flexibility, light weight etc. The power conversion efficiency (PCE) has been enhanced dramatically from ~2–3 to ~12 % through materials, interface and device architecture innovations such as tandem. This chapter focuses on multi-junction or tandem Solar Cell which is the architecture for highest Solar Cell efficiency. First, the principle of Solar photovoltaic process and the theoretical limits of Solar Cell in single and multiple junction Cells were presented. After the brief description of the realization of tandem Cell concept in inorganic Solar Cells, we provided an overview of the development of organic tandem Solar Cells. This includes two very distinct technologies—vacuum deposited small molecule tandem Solar Cells, and solution processed polymer tandem Solar Cells. The progress in active materials with different bandgap, interconnection layer, and tandem device structure are presented.
