    Korean company ASD challenge CdTe solar cells

    battery news 3 Comments

    Since 2002, commercial production of solar cell manufacturers U. S. First Solar, finally in 2009 with the release of the largest manufacturers of solar cells. The secret lies in its process of high-suction vacuum cleaner, without more, lower manufacturing costs CdTe (cadmium telluride), solar cells. Its strength can be described as overwhelming, if the Japanese solar cell industry, said: “In the manufacturing cost has been unable to catch up with First Solar.”

    Although CdTe solar cells have such a significant advantage, but perhaps because of the Cd (cadmium) toxicity distance, following the manufacturer’s production of First Solar few of these batteries. Has seven employees of Korean society risk Advanced Solar Dynamic (ASD) is one of them. A few days ago I interviewed ASD CEO Jay Lee Jae-Geun, he said with confidence “of the market based on CdTe solar cell to grow. The new space has also participated in the great enterprise.”

    ASD CdTe solar cell is characterized by the formation of the CdTe layer is different from First Solar. First Solar uses a “close to the sublimation: First, the sublimation material, then deposited on the ground at 600 ℃ high temperature process. The DSA is the process used in the temperature around 350 ℃ spray. Lee said: “This method can further reduce manufacturing costs,” it calls into question the king occupies the throne of First Solar.

    DSA in 2009 by 2-inch squares of test products to achieve a conversion efficiency of 12.6% (Voc than 775mV, JSC is 27.8A/cm2, FF 58.6%). In June 2010 began developing 20cm square module, also in December 2010 began to build can be made 60cm x 120cm wide 20MW module production line. Plan for the future through the layers in the structure of the series, to achieve a conversion efficiency of 25%.

    To achieve these goals need across many obstacles, so do not know if ASD smooth as expected. However, I think that plans already in place to build a culture of solar energy manufacturing plant to feed the crocodile in Taiwan, or SDA, many dynamic companies in Asia.

    Altairnano will supply advanced lithium-ion battery modules to Proterra

    battery news No Comments

    Altairnano has signed a long-term agreement with Proterra to supply advanced lithium-ion battery modules for incorporation into Proterra’s all-electric and hybrid-electric buses.

    Altairnano said that this technology will enable these buses to completely recharge in under 10 minutes, providing high levels of uptime and efficiency. Combined with cycle life, these batteries are ideally suited for the operating conditions experienced by commercial transit buses.

    The initial purchase order of $4.6 million is for delivery of modules through June, 2011 with ongoing orders anticipated thereafter as Proterra gains customer traction and completes its manufacturing facility in Greenville, South Carolina. This is a follow-on order to the two earlier orders announced in August, 2009 and April, 2010.

    Proterra’s electric and hybrid-electric buses are being marketed to municipalities and transportation authorities throughout the Americas and Europe. The two companies will work closely together to drive down the overall costs of the end product to the customer and add near-term credibility of a greener, more energy independent nation in the mass-transit arena.

    Terry Copeland, president and CEO of Altairnano, said: “This purchase and supply agreement represents a significant milestone and illustrates the growth opportunities present within the mass transit market. This transaction marks the culmination of more than two years of collaboration with Proterra.”

    Denmark Serenergy to supply British Microcab hydrogen fuel cells

    battery news 1 Comment

    British minicar maker Microcab company said on June 25 the company has ordered ten Danish company Serenergy 3 kW hydrogen power system for development of hydrogen fuel cell generation of hybrid vehicles.

    It is reported that Serenergy initial offer Microcab a module system. The system module contains the fuel cell, control systems and for the survey on hybrid batteries and electrical circuit conditioning training. The Microcab initially produce eight vehicles in support of the Coventry University next period of 12 months’ pilot project of ultra-low emission vehicle. ”

    Serenergy said to be the only manufacturer of high temperature PEM technology, and applied to European society of fuel cells. According to reports, the technology allows cars to a wider range of temperature, using less pure system of hydrogen fuel battery to improve the overall energy consumption.

    Microcab hopes to combine fuel cell hybrid car technology with minicar technology to develop a suitable light transport for urban and rural areas.

    Saft provides battery technology for SMUD PV Project

    battery news 1 Comment

    Saft will provide its lithium-ion battery technology to supply renewable energy storage for the Sacramento Municipal Utility District’s (SMUD) photovoltaic storage pilot program at Anatolia III, a high-penetration PV community within SMUD’s service territory.

    SMUD was awarded $4.3 million from the U.S. Department of Energy to conduct a two-year pilot project to examine the value of distributed PV coupled with energy storage in 15 homes and three sites on SMUD’s distribution system.

    The project will allow assessment of the PV system and energy storage capability and determine how well the storage systems perform during periods of peak demand, according to Saft. Through this pilot, SMUD will gain insights into the technical and economic feasibility of using distributed storage to enable higher penetrations of PV within its service territory.

    The role of the battery system is to provide efficient energy storage so that solar power can be time-shifted to support SMUD’s super-peak from 4 p.m. to 7 p.m.- particularly when PV output drops off after 5 p.m. According to Saft, Li-ion is the only technology that meets the project’s need for 20-year battery life in a range of demanding environmental conditions.

    Evergreen Solar introduced its highly efficient solar panels

    battery news No Comments

    The new ES-D ES-E series is specifically designed for residential and commercial, characterized by the use of new technologies the company Boost battery. This technology utilizes micro-pass line, instead of traditional bus to reduce the shadow of the battery, a traditional bus can significantly reduce the production of the battery, and even damage the battery.

    microwave transmission line current can be enhanced to take the whole we can improve the overall conversion efficiency of solar panels. The company said, this innovative battery technology also allows the battery plate has a good aesthetic appearance.

    The new solar array Evergreen Solar is a significant achievement, because this series of solar panels to provide more power, it reduces the impact on the environment, Evergreen Solar, said the vice president of marketing Scott Gish. He said that solar panels are the highest conversion efficiency of the company’s products to date, even if he did not specify the conversion efficiency.

    ES-D solar panels designed specifically for residential buildings. These panels smaller and lighter, therefore easier to install, and applicable to any shape and size of the roof.

    These products can be divided into two types: series of aesthetic effects, is a black, single panels, providing 195 watts, 200 watts and 205 watts of power, the other is the series of performance is to provide the best performance designed to provide 200 watts, 205 watts and 201 watts power.

    Meanwhile, the ES-E series of solar panels is ideal for commercial exploitation, it is because the large panels to help reduce installation costs. These panels are 220 watts, 225 watts and 230 watts of power.

    Both products will be launched at the end of this year.

    Evergreen Solar, Silicon “String Ribbon” maker of solar panels, using its proprietary technology, silicon technology for low-cost chip. It is reported that the process of production and consumption of oil on the traditional ingot forging and machining processing technology compared to the cost of lower and more environmentally friendly. The company said the new ES series of solar panels carbon footprint 30% lower than its competitors.
