Recently, 20 achievements from Nankai
University, Tsinghua University, Shanghai Institute of Optics and Fine
Mechanics and other institutions were selected as top ten progresses of “basic
researches” and top ten of “applied researches” at the “2017 China Optics Ten
Progress” conference, held by Chinese Laser Press. The project "Solution-processed
organic tandem solar cells with power conversion efficiencies >12.7%",
led by Prof. Chen Yongsheng (College of Chemistry, Nankai University), was
honored to be awarded as one of the “2017 China Optics Top Ten Basic Researches”.
Prof. Chen’s group used the
strategy of complementary light absorption, based on oligomers DR3TSBDT and
DPPEZnP-TBO to construct a stacked organic solar cell device with broad spectral
absorption characteristics. This is the highest record of the photoelectric
conversion efficiency of organic solar cells reported in the literature, as of
the award date. The research achievement was
published in Nature Photonics: http://www.nature.com/articles/nphoton.2016.240.
Researcher in the group
introduced that, according to the relevant design principles, through the
further optimization of materials and devices, the device's various indicators
including photoelectric conversion efficiency still have much room for
improvement. It is expected that in the near future, more than 15% of
photoelectric conversion efficiency will be achieved.
"Next work of our team is mainly to solve the problem of battery life,
and further increase the efficiency of energy conversion. It can be believed
that the dream of making the organic solar cells from laboratory to possible
OSC commercialization will become a reality in the near future." Prof.
