Japan HIT solar photovoltaic conversion rate high with nikon en-el3e battery
Recently, Japan’s Sanyo Electric Co. said it developed the company’s amorphous silicon-germanium mixed heterojunction (HIT) solar cells at the research stage reached 22% of the photoelectric conversion rate, creating more than 100 square centimeters and practical class size HIT solar nikon en-el4 battery photoelectric conversion rate of a new record.
It is learned that, HIT solar cell is a kind of crystalline silicon-based panels and the use made of amorphous silicon thin-film hybrid solar cells. Such solar cells per unit area of the generating capacity to maintain the world’s leading standard. Sanyo’s researchers developed a new cleaning technology, this technology enables single crystal silicon surface cleanliness higher, while inhibiting formation of the amorphous silicon layer on the surface of single crystal silicon damage. Through these improvements, the dell 8N544 battery power output of power loss decreased.
In addition, the researchers also by adjusting the cell surface of micron bump size, a more full use of sunlight. It is understood that the photoelectric conversion rate of solar cells is directly related to the cost of solar power generation system, so competing countries in the world dell C1295 to study this subject.

Take Fujitsu Lifebook T5010 Battery solar cells, “a house built on the” Shanghai to build solar power demonstration building
Buildings like a giant solar arrays, each generating 1.1 million-degree autonomy, while saving 780 thousand degrees. The Shanghai Solar Energy Engineering Technology Research Center for two years planning and design, in Shanghai the first “megawatt-class” solar power system grid demonstration project, yesterday in Minhang Zizhu Science Park under construction, completed in July next year. A series of practice “integrated solar energy building” concept of scientific and technological achievements, are expected to apply to the Shanghai World Expo venues.
According to the plan, demonstration project by the five buildings, namely office building Fujitus Battery, laboratory building, living homes. The roof and facade of these buildings and so on, by various forms of solar cells “packaging.” Project covers an area of 26.7 thousand square meters, solar components area of 10.5 thousand square meters, “solar energy coverage” for about four into. Works with a “solar building materials”, there is opacity of the solar curtain wall, there are translucent glass-based solar cells; a double-sided solar cells, also have solar tiles; there is solar energy “shading system”, as a block of solar panels strung together in “blinds.”
Nuances, see “Sunshine”, built-up areas will also make full use of lighting the sun. 26 lamps used in all solar energy or “wind energy – solar energy,” complementarity; 60 Lawn also rely on photovoltaic power generation; some of the buildings at the entrance to the glass ceiling, but also the use of solar panels and semiconductor lighting the double integration of energy-saving design ; Even the park’s sculptures drawn sketches also consider solar cells. Most definitely a “Sunflower” solar light into the system, each sub-set of the glass like a pot of sunflowers from the 12 lens consisting of a small “flower” direction and rotation sensor in direct sunlight, the light energy directly into light . , One Taiwan “Sunflowers Light” with only 0.9 kWh per month, the project install applications in the basement of 1,200 square meters, the annual saving 35 thousand degrees with fujitsu lifebook s6120 battery.
This is not only energy-efficient green buildings have appropriate living environment. In the absorption of light energy at the same time, the wall using foam glass and other advanced multi-barrier material; the heating system-wide collection of hot and cold air-conditioning can be self-driven and to achieve joint for hot water. It is understood that the base can accommodate 200 technical staff working life, both solar energy research, experiment and demonstrate the function spaces, are responsible for “Expo solar and semiconductor lighting applications and planning studies” project, a large number of renewable fujitsu lifebook s7220 battery energy saving technology will be external migrated.
