Paying for solar on commercial rooftops; more-efficient polysilicon and thin-film solar cells; JPMorgan buys into carbon trading; biogasoline; and GreenFuel Technologies' progress could mean the first commercial-scale algae fuel plant.
Lux Research forecasts a shakeout as new technologies give polysilicon cells more competition. But strong demand and rapid growth remain.
In China, making polysilicon to meet the booming demand for solar panels is leaving behind toxic waste, according to a report.
Its manufacturing process and improved polysilicon efficiency will produce grid-parity pricing within a few years, start-up Suniva claims.
ST Liquid Crystal Display puts $91.4 million into expanding its production of low-temperature polysilicon LCD panels.
Toshiba announced Monday that it has developed a large, flexible liquid crystal display. The 8.4-inch low-temperature polysilicon screen is flexible enough that it can be bent into a curve while displaying images, bringing the technology closer to the ultimate goal of foldable displays. The screen is less than 0.4mm thick and weighs less than 20 grams. Toshiba is working to have the screen technology ready for mass production by 2005 but will present it at the Society for Information Display 2002 conference, in Boston, Mass., from May 21 to May 23.
Toshiba showed off for the Japanese market a new mini-notebook that the company claims can provide up to 14 hours of battery life. Part of the power savings comes from a low-temperature polysilicon display, Toshiba said. A larger, optional battery has to be used to achieve the longest battery time. The new notebook contains a 5800 Crusoe processor from Transmeta, a 20GB hard drive and 256MB of memory; it runs at 800MHz. It will cost between $1,000 and $1,300, depending on the configuration, and will be officially released May 18. Toshiba is one of Transmeta's largest customers but has not brought one of the notebooks to the United States.
The Japanese company is bringing its low-temperature polysilicon display technology to notebooks in hopes of eventually lowering their price.
Toshiba and Matsushita, known for its Panasonic brand, announced Friday they will establish a Singapore-based company to manufacture low-temperature polysilicon LCDs (liquid crystal displays). Production of the LCDs is scheduled to start in July 2002. Capacity is expected to reach 55,000 29-inch-by-36-inch panels per month by 2003. The panels will be used for mobile phones, handheld computers and flat-panel televisions.Toshiba will invest 67 percent of the initial $431 million of capital needed to start the company; Matsushita will invest the remaining 33 percent.
