 The Japan Society of Applied Physics (JSAP) and the Materials Research Society (MRS) were excited to jointly sponsor multiple symposia as part of the 2013 JSAP Autumn Meeting, which was held in Kyoto, Japan on September 16-20, 2013.

 The 2013 JSAP Autumn Meeting in Kyoto offered a wide range of research topics in materials research, which include for the first time 23 joint JSAP-MRS symposia in addition there was a Fred Kavli Distinguished Lecture in Nanoscience.

 Meeting gathered experts, academics, company representatives from around the world for up to three thousand people. The MRS-JSAP has a total of more than a dozen seminar venue , a number of topics related to nano-materials, ferroelectric materials , oxide films, smart materials , photovoltaic , photocatalysis and so on.

 Cu-based ternary chalcopyrite photovoltaic materials, including CIS ( copper indium selenide ) and CIGS ( copper indium gallium selenide ) and other such material is recognized as the most promising thin-film solar cell materials . CIGS cell efficiency has reached 20.3%, but the use of expensive CIGS scarce indium, gallium, so development is limited. So CZTS (copper-zinc tin sulfur) instead of CIGS as a light-absorbing layer becomes an international hotspot. Japanese research group prepared using the sputtering sulfide CZTS battery reaches 6.7 % efficiency, while IBM Preparation of composite coating technology CZTSSe ( copper zinc tin sulfur selenide ) cell efficiency reached 11.1% . More and more research groups have been prepared by various methods CZTSSe battery. The other non-indium Cu-based chalcopyrite materials such as Cu₂SnS₃ (CTS) and Cu₂SnSe₃ (CTSe), has also been of great concern.

 In recent years, our department Superconductivity and New Energy Research and Development Center has made a number of innovative researches in the study of thin film CIGS solar cells. By participating in this international conference, our results of the researches on CZTSe battery materials have be shown in an international showcase and we expanded the visibility of our school. I believe that our future research direction in CZTSe batteries will play an active role in guiding.
