Vacuum insulated glass, 'Glavenir'

Panasonic has manufactured and rolled out thin vacuum insulated glass with approx., 6mm thickness which is very thin. The glass featured with industry's top class insulation performance*6 , where the technologies that Panasonic has retained in the course of developing and manufacturing Plasma Display panels, are applied.
In addition to the float glass*7 specifications that have been rolled out so far, we have developed vacuum insulated glass using tempered glass specifications. The glass with approximately 8mm thickness, has realized 0.58W/m2・K, which is industry's top class thermal transmittance
In manufacturing process, vacuum insulated glass is welded with a sealing material that was made by melting two sheets of glass at a high temperature. In general, tempered glass loses its strength when heated at a high temperature. Therefore, we newly developed original 'Ultra-low temperature sealing material'. With the new sealing material, we have realized welding tempered glasses at a temperature range without reducing their strength. In addition, we have succeeded in putting the pillars that support the vacuum layer into practical use for transparent vacuum insulated glasses for the first time in the industry*8. As strong pressure is usually applied to the pillars, opaque material with high strength such as metal is used for the pillars. However, Panasonic has succeeded in developing a vacuum insulated glass with transparent pillars by developing a new 'transparent insulating material with high strength' for the pillars. With the glass where the new material is used for the pillars, users have a noiseless view with subdued presence of pillars more than ever before. Currently, multi-layered/triple glasses are often used for doors of refrigerator/freezer showcases. However, in pursuing to improve insulation property of the glasses with conventional technology, the door will be thicker and heavier. Therefore, 'Glavenir' will contribute to further improve its energy saving performance, solving such issue.

Photovoltaic (PV) Module, 'HIT'

Panasonic HIT® Photovoltaic (PV) Module is featured with high energy conversion efficiency and excellent temperature characteristics by its unique heterozygous structure combining a single crystal silicon substrate with amorphous silicon layers. With the technology that reduces energy loss caused by reunification of positive and negative electric charges generated by sunlight, the 'HIT' minimizes loss of the energy generated by the PV cell and improves its power generation performance. The reduction ratio of the output amount of the energy is small when the temperature of 'HIT' panels become high during daytime, because the amount of power generated per effective area of a cell is large. Therefore, with 'HIT', larger amounts of power generation can be expected using the limited area of the cell panels.

For home use of 'HIT', by using the standard type with the half-type or trapezoidal type in a combination, it is possible to install larger capacity of 'HIT' cell panels even on a rooftop with complex shapes and/or small roofs. For public and industrial use, we also offer different types of 'HIT' to be suited to the needs for applications.
