＜正＞ No information on the heat- resistant properties of CIGS thin film solar cells has been reported so far although it is very important for practical usage of this device. In this contribution, we present the heat-resistant properties of CIGS devices with CBD （Chemical Bath Deposition）-CdS or CBD-ZnS buffer layers. The CIGS thin film solar cells were heated at temperatures ranging from 100 to 450°C in a vacuum for 30 min. It was found that the CdS/CIGS and ZnS/CIGS devices were stable below 320°C and 350°C, respectively. These results suggest that CIGS devices possess high heat-resistance for practical applications. SMS and EBIC analyses revealed that the main cause for the deterioration of CIGS devices at high temperatures is attributable to the change of junction properties due to the excess diffusion of Cd or Zn into CIGS absorber layer.

Case Reports in Clinical Medicine 2017年第10期6卷 281-284页

作者： Yuta Ito Yuko Hamada Keiko Katayama Hirokazu Uno tokio nakada Department of Dermatology Showa University Fujigaoka Hospital Yokohama Japan

A 50-year-old woman presented with a 1-week history of rash on the face and hands and difficulty when rising from a sitting position. She underwent an exploratory laparotomy for ovarian cancer 8 months ago. Three months ago, she underwent total hysterectomy, adnexectomy, and retroperitoneal lymph node dissection. Docetaxel and carboplatin were started and administered twice. Physical examination revealed periorbital edema with a purplish appearance;Erythematous lesions on radiodorsal aspects of the proximal interphalangeal and metacarpophalangeal joints were seen. We diagnosed as dermatomyositis on the basis of clinical findings. Interview demonstrated that such rashes were enhanced 1 week after chemotherapy, and got better through following one week. Cutaneous and muscular symptoms got worse two months after her initial visit. Myotonia was found in electromyography, and high density areas on both femoral regions and lower thighs were observed by MRI of skeletal muscle. Scleroderma-like lesions are known as an adverse effect to taxane. In addition, three cases of dermatomyositis due to taxane were reported in Japan. Since dermatomyositis was regarded as one of paraneoplastic syndrome generally, it was not considered as drug-induced. However, clinical course of our case suggests that docetaxel may play more important role in activity of dermatomyositis than ovarian cancer. Seeing patients treated with taxane, therefore, we have to be careful for symptoms suggestive of autoimmune diseases: not only scleroderma but dermatomyositis.

Ga Content Dependence of Cell Performance for Bifacial CIGS Thin Film Solar Cells

Cu(InGa)Se (CIGS)-based thin film solar cells have been fabricated using indium tin oxide (ITO) back contacts. The device performance was affected by Sn/In atomic ratio in ITO back contact. In particular, V and FF were improved by an increase in Sn/In atomic ratio. The morphology and grain size of the back contacts depended on the Sn/In atomic ratio. These results indicate that the device performance was enhanced with a decrease in grain size and a modification on morphology of ITO back contacts. The improvements of V and FF should be attributed to the increase in Na content in the CIGS layers, because the rate of the Na diffusion through ITO films into CIGS layers is affected by the microstructure of ITO back contacs.

＜正＞ Bifacial CIGS solar cell with a ZnO:Al/ZnO/CdS/CIGS/ITO/SLG structure using ITO （Indium Tin Oxide） back contacts have been fabricated. In this contribution, the details of fabrication and performance of bifacial CIGS thin film solar cells are described. The cell performance of the CIGS device was improved by optimizing Ga content in the CIGS layer. A best cell showed total area efficiencies of 12.6% and 7.4% for front and rear side illumination, respectively. This result implies that the maximum equivalent cell efficiency of 20.0% could be obtained when both sides of the bifacial device were illuminated simultaneously under AM1.5, 100 mW/cm2 conditions.

NAREGI is a 5-year Japanese National Grid Project during 2003--2007, whose chief aim is to develop a set of grid middleware to serve as a basis for future e-Science. NAREGI also aims to lead the way in standardization of grid middleware, based on the OGSA architecture. Its super-scheduler is based on the proposed OGSA-EMS Architecture, in that it becomes the first working implementation that implements the documented component relationships within the OGSA-EMS architecture document v.l.0. Through the efforts and experience in the design and implementation, it has been confirmed that the documented OGSA-EMS architecture is quite feasible, but will require significant amount of refinement and speed improvements to finalize its detailed specifications. The super-scheduler also supports co-allocation across multiple sites to support automated execution of grid-based MPIs that execute across machines. Such a resource allocation requires sophisticated interactions between the OGSA-EMS components not covered in the current OGSA-EMS architecture, some of which are non-trivial. Overall, job scheduling with OGSA-EMS has proven to not only work, but also that its job allocation and execution time is within reasonable bounds.

The possible final states for the decay K^0→ π＋π-π^0 have isospinI = 0, 1, 2, and 3. TheI= 0 andI= 2states have CP = ＋1 and Ks can decay into them without violating CP symmetry, but they are expected to be strongly suppressed by centrifugal barrier effects. The I = 1 and I = 3 states, which have no centrifugal barrier, have CP = -1 so that the Ks decay to these requires CP violation.
