Full-scale Mass Production of Solar Cell Conductive Film for PV Module by Sony

September 7, 2010 · Filed Under Clean Tech, Green Tech · Comments Off on Full-scale Mass Production of Solar Cell Conductive Film for PV Module by Sony 

Sony Chemical & Information Devices Corporation has begun full-scale mass production of solar cell conductive film for photovoltaic modules. The SP100 Series is a film-type conductive bonding material that bonds solar cell with metal ribbon which acts a conductive line for the electricity generated by the cell. The new SP100 Series offers a low-temperature bonding at 180 degrees Celsius in comparison to conventional soldering of 200 degrees Celsius or more, resulting in significant reduction in residual stress after bonding on cells for an improved yield during module production. The SP100 Series can also be used to bond thin cells measuring approximately 150?m, which are weaker against thermal stress during soldering than standard thick solar cells. The SP100 Series uses Anisotropic Conductive Film (ACF) technology which normally used for such applications as mounting of a driver IC on an LCD panel, providing a stable contact between the solar cell and metal ribbon through heating and pressurizing conductive particles which has been distributed evenly into the epoxy-type resin, resulting in simultaneous heat-curing of the resin and reliable conductive equivalent to that of soldering.

Development of Novel Technology for Accurate Measurement of Hydrogen content in Production of Thin Film Solar Cell

June 23, 2010 · Filed Under Clean Tech, Green Tech · 2 Comments 

Some of key major issues hampering proliferation of silicon based solar cells are their high cost and low performance. The high cost usually associated with the manufacturing cost of these types of solar cells, and the low performance is normally associated with excess hydrogen which is introduced during the process of forming amorphous silicon films on glass substrate. Based on this manufacture of solar cells have turned their attention to thin film silicon solar cells, where a large-size cell panels can be manufactured using only a small amount of silicon, ideal for mass production based on their excellent cost performance. On the performance issue though, up to now there has not been a sufficient developed technology to accurately analyze the hydrogen content that occurs during the manufacturing of thin film solar cells. To overcome this major issue, Dainippon Screen Mfg. Co., Ltd. and Gifu University have successfully developed a novel technology that analysis the characteristics of amorphous silicon films during the production of thin film silicon solar cell panels, paving the way for development of next generation low cost solar cells.

Development of Solar Cell with World’s Highest Conversion Efficiency by SHARP

October 22, 2009 · Filed Under Green Tech, Trendy Products · Comments Off on Development of Solar Cell with World’s Highest Conversion Efficiency by SHARP 

Achieving the highest possible solar energy conversion efficiency is at the heart of any solar cell research and development effort, and sharp is no stranger at this. Sharp started the development of its first solar cell back in 1967 by developing a solar cell for space application using single-crystal silicon. Much later on the company began its R&D on triple-junction compound solar cell to further improve efficiency, reduce weight, and increase durability of solar cells which was targeted for space applications. Through this effort in 2003 Sharp achieved 31.5% conversion efficiency. By today’s announcement using the same solar cell structure Sharp at least at the experimental level has achieved a 35.8% conversion efficiency rate. Read more

Development of Ultra thin HIT Solar Cell by SANYO

September 18, 2009 · Filed Under Clean Tech, Green Tech, Trendy Products · Comments Off on Development of Ultra thin HIT Solar Cell by SANYO 

Sanyo Electric made an announcement today on development of Ultra thin HIT (Heterojunction with Intrinsic Thin-layer) solar cell which by the way is Sanyo’s originally developed technology. The HIT is a hybrid model combining a crystalline silicon substrate and an amorphous silicon thin film. The first announcement on such HIT solar cell by Sanyo was back in May of this year achieving a world’s highest conversion efficiency of 23%. Well this time the conversion efficiency is at 22.8% but the cell thickness is 98?m which is half the thickness of the previous model. This is an important achievement since by reducing the thickness of the silicon wafer in order to save resources and reduce cost would result in less optical absorption which causes the energy conversion efficiency to drop.
