In order to achieve the midterm goal of “module conversion efficiency over 6%”, we worked on the development of planar modules. As a result, the modules of 20-cm-square and 5-cm-square with conversion efficiency of 6.8% and 8.2%, respectively, were successfully developed. These efficiency data were obtained in precise measurements by AIST, and the efficiency value of 6.8% was listed on the solar efficiency tables as the world record. Furthermore, we have started the fabrication of 30-cm-square modules using advanced and original manufacturing apparatus. The technologies we developed for the modules in this fiscal year were; highly-integrated module design technology, large-area and accurate printing/patterning technology and optical management technology. By the improvements of meniscus coating technology, high opening area ratio up to 94% and, as a result, module efficiency as high as 8.2% were realized in the newly designed 5-cm-square modules. To attain another midterm goal of “cell conversion efficiency over 8%”, we also developed the cell structures, materials and fabricating process. As a result, a conversion efficiency of 9.6% was successfully attained in 1-cm-square cell. For this purpose, we developed novel p-type polymers, n-type materials, intermediate layer materials and optimum cell structure. By using low band-gap p-type polymer, which absorbs the longer wavelength light as high as 800nm, Jsc and FF increased up to 16.9 mA/cm2 and 0.73, respectively. The conversion efficiency was improved by the band matching and thickness optimization of intermediate layers. The third midterm goal of “the relative efficiency decrease smaller than 10% in the durability tests” was also attained by the development of sealing technology, heat-resistant donor materials and fabricating processes. I all the five durability test, that is, thermal cycling test, temperature/humidity cycling test, light exposure test, heat test and damp heat test, relative decreases in efficiency were lower than 10%. For the application developments, some electronic devices equipped with OPV as the power supply, for instance, the sensor devices were prototyped. It was confirmed that they work well under indoor lighting.
