Development of World’s First Conductive Silver Ink to form Electronic Circuits by UV Light

January 24, 2012 · Filed Under Trendy Products · Comments Off on Development of World’s First Conductive Silver Ink to form Electronic Circuits by UV Light 

TANAKA Kinzoku has announced the development of a special silver ink which can be hardened without heating by applying only Ultraviolet (UV) light to be used for electronic circuits. The new discovery will enable the electronic wiring possible at room-temperature since no heating is required. Hence, by using the newly developed silver ink it is possible to perform wiring not only on glass base material and substrates, but also on flexible base materials such as polyvinyl chloride film (PVC film) as well as polyester film (PET film), which up to now was difficult due to their susceptibility to heat.

Development of a New High Efficiency Single Crystalline Solar Cells by Sharp

December 1, 2010 · Filed Under Green Tech, Trendy Products · 1 Comment 

Sharp has made an announcement on development of a new single crystalline solar cell with high conversion efficiency. The new solar cell uses a Back Contact structure, where the electrodes are connected on the back-side, helping to eliminate any needs for electrode to be set on the front side. The new structure increases the light receiving area on the front side surface. Read more

Development of a Conductive Film for Bonding Tab ribbon for Solar Cells by Hitachi Chemical

October 22, 2010 · Filed Under Green Tech · Comments Off on Development of a Conductive Film for Bonding Tab ribbon for Solar Cells by Hitachi Chemical 

Hitachi Chemical announced the development of “CF Series”, a conductive film for bonding tab ribbon when connecting crystalline silicon solar cell in a series formation. In addition to this the new conductive film can be applied to thin film as well as organic compound PV modules. Development of the new conductive thin film was in a direct response to find an alternative material to solder in the case of a thin film. Currently, solder is used for connecting a tab ribbon to a bus bar; however soldering requires a high temperature which imposes stress on the cell, resulting in a bend or even a crack. Read more

Development of a Method for High Purity Separation of SWCNT by AIST

February 5, 2010 · Filed Under Trendy Products · 2 Comments 

AIST SWCNT sepeartion method1Carbon nanotubes (CNTs) come in two main forms,one being the single-walled carbon nanotubes (SWCNT) and the other is the multi-walled nanotubes (MWCNT). The structure of a SWCNT is a one-atom-thick layer of graphite which is called graphene, wrapped into a seamless cylinder with open or closed ends. Depending on the arrangement of the carbon atoms, SWCNT exhibits metallic or semiconducting properties. Normally, the synthesis of SWCNTs yields a mixture of these two types. However, if the these two types can be separated in high purity, they can be utilized in many potential applications. For instance, metallic SWCNTs can be used as transparent electrodes in production of liquid crystal displays or solar cells instead of the transparent conductive materials which is prepared using rare metals, also the metallic SWCNTs can be used in wiring ,in development of high-integration high-speed SWCNT computers. On the other hand semiconducting SWCNT can be employed as transparent and flexible transistors. Read more

Development of Large Capacity High Voltage Lithium-ion Battery System by SANYO

November 17, 2009 · Filed Under Green Tech, Trendy Products · 1 Comment 

Sanyo made an announcement on launch of two large lithium-ion battery system models. The new battery system (DCB-101) is designed to be easily integrated into the existing systems as part of hybrid schemes using solar cells to store electricity generated by wind power or for electrical output stabilization where as, the new (EVB-101) for Electric Motors can be used to power light electric vehicles that are in the R&D or small scale mass production stages.

Development of Solar Cells with World’s highest Energy Conversion efficiency by SANYO

May 22, 2009 · Filed Under Clean Tech, Green Tech · 1 Comment 

Looks like Sanyo is all alone in this field by breaking its own record in developing the world’s highest energy conversion efficiency of 23% for crystalline silicon type solar cells for a practical size of 100 cm2 or more. The solar cell is of HIT (Heterojunction with Intrinsic Thin layer) type composed of thin crystalline silicon wafer sandwiched by ultra-thin amorphous silicon layer. HIT structure offers a reduction of recombination loss of the electrical element (charged carrier) by surrounding the energy generating layer of single thin crystalline silicon (c-Si) with high quality ultra thin amorphous silicon (a-Si) layers.

Development of highly flexible new conductive material by Fujifilm

April 17, 2009 · Filed Under Green Tech · 1 Comment 

ITO or otherwise known as “Indium tin oxide” is mainly used to form the transparent conducting coatings for wide array of applications such as Liquid Crystal Display (LCD), flat panel display, plasma display, touch panels, electronic ink, organic light-emitting diodes, solar cells, etc. But due to high cost and limited supply of indium, the fragility and lack of flexibility of ITO plus the costly layer deposition requiring vacuum manufacturers of such products are looking for alternatives. Based on this, Fujifilm made an announcement on a newly developed conductive material to replace ITO for transparent electrodes in above applications according to Fujifilm. Read more
