A new type of a-Si/c-Si heterojunction solar cell, called the HIT (Heterojunction with Intrinsic Thin-layer) has been developed based on ACJ (Artificially Constructed Junction) technology. conversion efficiency more than 18% achieved, which is highest ever value for cells in junction was fabricated at a low temperature (<200°C).

We have achieved a very high conversion efficiency of 21·5% in HIT cells with size 100·3 cm2. One the most striking features cell is its open-circuit voltage Voc, excess 710 mV. This due to excellent surface passivation at a-Si/c-Si heterointerface realized by Sanyo's successful technologies for fabricating high-quality a-Si films and solar low plasma damage processes. studied ways treat produce good interface throughout our fabrication also investigated deposition conditions layers...

Polycrystalline silicon (poly-Si) thin films prepared by the solid phase crystallization (SPC) method were investigated for application as photovoltaic materials. To improve properties of poly-Si film, two methods developed to control crystallization. One is partial doping method, in which starting material a-Si consists a doped layer and an undoped layer. We have succeeded controlling nuclei generation using doping, high mobility 196 cm 2 /V·s was obtained at carrier concentration 1×10 18...

For further improvement of conversion efficiency in a-Si solar cells, it is necessary to develop materials with high photosensitivity the long-wavelength region. A new solid phase crystallization (SPC) method was developed grow a Si crystal at temperatures as low 600°C. Using this method, high-quality thin-film polycrystalline silicon (poly-Si) Hall mobility 70 cm 2 /V·s obtained. Quantum range 800 nm ∼ 1000 achieved up 80% an experimental cell using n-type poly-Si grain size about 1.5 µm....

The number of octogenarian lung cancer patients undergoing radical surgery has been increasing recently. However, knowledge regarding the risk factors for postoperative complications and reliable predictive long-term survival is limited. This study aimed to investigate complications, prognostic factors, in older than 80 years.Lung aged years or who underwent were retrospectively studied; a multi-institutional analysis was conducted from January 1998 December 2015. Preoperative clinical data,...

Abstract The structural effect of polyanions on the binding type methylene blue ( 1 ) was investigated spectrophotometrically. bound to poly(potassium styrenesulfonate) (PSS) and poly(sodium 4‐vinylphenylsulfate) (SVS) in dimeric or slightly aggregated form vinylsulfonate) (SVF) vinyl sulfate) (PVS) highly (polymeric) form. It found that flexibility plays an important rǒle aggregation difference between SO OSO as site is not a significant factor.

A HIT (heterojunction with intrinsic thin-layer) structure solar cell has been developed. In this structure, a nondoped a-Si thin layer was inserted between p-type and an n-layer c-Si substrate. The open-circuit voltage fill factor (FF) were significantly improved in these cells compared conventional p/n heterojunction cells. improvement seems to originate the reduction of backward current density.
