Nature 太阳能光伏 9.2%, 华工吴宏斌课题组

Enhanced power-conversion efficiency in polymer
solar cells using an inverted device structure
Zhicai He, Chengmei Zhong, Shijian Su, Miao Xu, Hongbin Wu* and Yong Cao
Polymer-fullerene bulk heterojunction solar cells (PSCs) are
currently attracting a great deal of attention and gaining
increasing importance, having already shown great promise
as renewable, lightweight and low-cost energy sources1–4.
Recently, the power-conversion efficiency of state-of-the-art
PSCs has exceeded 8% in the scientific literature5. However,
to find viable applications for this emerging photovoltaic technology,
further enhancements in the efficiency towards 10%
(the threshold for commercial applications) are urgently
required6. Here, we demonstrate highly efficient PSCs with a
certified efficiency of 9.2% using an inverted structure, which
simultaneously offers ohmic contact for photogenerated
charge-carrier collection and allows optimum photon harvest
in the device. Because of the ease of use and drastic boost in
efficiency provided by this device structure, this discovery
could find use in fully exploiting the potential of various
material systems, and also open up new opportunities to
improve PSCs with a view to achieving an efficiency of 10%.

其实这篇文章的材料不新，电池结构也不新，就效率还可以，我上面说错了，应该是最多发AM...

不过很多时候所谓的新都是为了发好文章故意改的，实际上改的可能和没改一样。特别是polymer上到处改改，都没什么新意的，拼的就是手艺。
有新意或者性能好都是可以发AM的，这篇发AM是没有问题，虽然比上一篇8.37%的文章写得要差。上一篇被nature photonics拒了后投给AM都没送审，主编直接接受。
不过nature photonics也是要求性能好，对新意要求不高。同样的文章发到nature Materials上就更要求新意。
不过这个组就这个PFN换了各种polymer发了各种好杂志，这个从学术上来说没什么太大贡献。
