Solar business from Korea

Researchers in South Korea have suggested a new approach to creating cost-effective and more efficient dye-sensitized solar cells, which will mean significant advancement in the thin-film market. So far in the development of this thin-film technique, researchers have faced one major setback; the efficiency of the cells has been half that of the more commonly used silicon-based cells. However, this new approach will improve the power consumption rates of dye-sensitized solar cells by at least 50%. Park Nam-gyu, a researcher from the Korea Institute of Science and Technology (KIST), said his team has discovered a breakthrough method, which enables a sequential bonding of dyes in the thin, titanium dioxide (TiO 2 ) layers used in dye-sensitized solar cells. Park said, ''In the existing prototypes, the TiO 2 films bond with just one kind of dye, and developing techniques to allow the films to absorb dyes of different colours, thus allowing the solar cell to absorb and use a broade...

As the first Chinese thin-film manufacturer to produce tandem junction cells on a production line, ENN Solar Energy Co., Ltd. has passed another milestone with its receipt of certification from TÜV InterCert for its tandem junction silicon thin-film solar modules. This certification confirms that the modules comply with the IEC’s requirements, and effectively passes the modules for sale in European and U.S. markets. With this TÜV Certificate, ENN solar becomes the first manufacturer in Asia to receive the certification for ultra-large size tandem junction silicon thin-film modules. The half- and quarter-size modules also received the certification, which concludes that all of ENN’s module sizes are in compliance with the requirements of IEC 61464 and IEC 61730. The 5.7m 2 modules were produced on its 60MW Applied Materials ‘SunFab’ line, ramp-up of which took place in March 2009. EEN Solar has aggressive plans to ramp manufacturing capacity to 500MW by 2011.

Focussing its research capabilities on the thin-film sector, LG Display is looking to the future of solar energy with its recent investment of 50 billion won ($40 million) in a pilot line and testing facility for solar cells. The pilot line will be built in LG’s Paju display complex in Korea later this year, while an outdoor test power generation facility will also be constructed at the site. The pilot line will enable the testing and research of thin-film solar cell efficiencies, with the company aiming to achieve an increase in the current energy conversion efficiency rate of 8% to 12% by 2010. Commercialization, planned for 2012, will occur when the research facility has raised the cells’ efficiency to 14%, enabling the manufacturing cost to be lowered to less than US$1 per watt. LG Display’s target market in this phase will be commercial applications buildings and public displays, graduating to solar cells for mobile displays, automobiles, and eventually to supplying cells for suc...

SoloPower today became the first US ANSI/UL 1703-certified manufacturer of flat-plate, CIGS based (copper indium gallium selenide) PC module. The Silicon Valley-based producer of thin-film solar photovoltaic cells and modules is well on the way to its goal of mass-producing PV modules. Intertek, an independent, multi-national product safety certification organization, granted the ETL certification. The product was tested to meet ANSI/UL 1703, the developed standard for safety flat-plate photovoltaic modules and panels. Being certified is an important technical and commercial achievement for SoloPower’s products in the US and Canada. The certification is an added third-party confirmation that the company’s PV modules conform to rigorous safety standards.

It's my selling item packgae LDPE(Low Density PolyEthylene) film scrap, make pressed in bale for 40 foot container loading it's only natural color and see the picture some dirty on surface because pollution of surface in presse processing from machineru or ground but inner side very clean can be supply about 3 or 4 x 40FCL/month, about 22-24MT in 40 ftoo container who is interest it feel free contact me

A new report from market research firm, IC Insights highlights the expected recovery in capital spending within the photovoltaics industry as the market recovers over the next few years. The market research firm claims that spending on manufacturing plants, equipment and materials in both the crystalline (c-Si) and thin film sectors has not declined as much as PV manufacturers had wanted in light of the slump in demand and difficult financial conditions, restricting project finance for solar installations. IC Insights said in the report that it was late in 2008 that major PV manufacturers started to make capital spending cuts as the scale of the decline in demand became clear. Although many significantly reduced spending budgets for 2009 compared to 2008, long-lead times and previously planned expansions already taking place meant that many manufacturers could not abruptly halt all expenditures. Although 2008 was a record year for PV installations, production capacity was already growi...

Taiwan’s government reports that it has passed a bill on renewable energy that is expected to attract Taiwan $30 billion (US $937 million) worth of investment. Parliament approved the measure on 13 June 2009, which is aimed at adding between 6,500 and 10,000MW of installed energy from renewable to Taiwan’s current 2,287MW (5.8%) over the next 20 years. Before this bill passed, providers were obligated to sell electricity to state-run Taiwan Power at Taiwan $2 per kilowatt-hour, compared with the Taiwan $8 they recommended. The bill is part of the government’s plan to reduce carbon dioxide emissions to 2000 levels by 2025.The government now plans to offer incentives and loosen regulations on renewable energy providers, in addition to creating a pricing mechanism for various sources of solar or wind energy. United Daily news estimates that the bill will induce over Taiwan $30 billion in investment in the first year and create more than 10,000 jobs. Needless to say, industry watchers wel...
