[资源] 华南理工大学吴宏斌教授 9.2% 聚合物太阳能电池发表在naturePhotonics上面

评价下啊，赚点金币！文献报道最高效率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 tech-
nology, 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%.
