Central south university progress in the field of organic solar cells

It was also because 300% of the volume expansion, limit the commercial application of silicone material. Now solve silicon the expansion of the charge and discharge method of the research on nanometer silicon, porous silicon, silicon composite materials. The use of synergies between the composite components, to achieve the purpose of complementary advantages, including silicon, carbon composites is an important research direction, including coating, embedded and distributed.

the reporter learns 1 from central south university, internationally renowned journals joule and nature communications chemicl engineering professor Zou Yingping central south university recently published research organic solar cell material design series results of synthesis and mechanism research. The work to promote the efficiency of organic solar cell research and development, industrial production has a positive impact in the future.

is a kind of organic solar cells convert solar energy to electricity of new electronic devices, because of its low preparation cost, photoelectric characteristic is easy to adjust, can be made of translucent and large area & other; The roll printing & throughout; Wait for an advantage, has become the research hot spot. The main indicators of the solar cell performance is its energy conversion efficiency. Highly efficient organic solar cells is still the principal goal of the present study, is also the key to realize its industrialization.

professor Zou Yingping group in addition to consider organic solar cell materials complementary energy level matching, absorption spectrum and mobility of balance, also from the point of view such as thermodynamics, space configuration material compatibility, and synthesis of organic small molecular receptor photovoltaic material. This kind of small molecular receptors can effectively broaden the absorption spectrum, reduce the voltage loss, for material synthesis provides a new way of thinking.
