Flash mode to collect solar cells

A variety of techniques to promote the "mini-flash" came
U.S. scientists at Sandia National Laboratories announced that they invented a new type of solar cell - "micro-flash" solar cells. Such solar cells made of crystalline silicon used in the manufacture of electronic devices by adding a plant widely used in today's micro-electromechanical systems (MEMS).
Under the same conditions can produce the same amount of power, the new battery is only common silicon solar cells required 1%. And because small, it is not vulnerable to external environmental damage caused by the shape, it needs long-term use in some environments have obvious advantages. This battery can cost less efficient.
This small cell size, their structure, thickness of about 14 to 20 microns, but the results are compared favorably with conventional solar cells. It can be installed in the charger and then placed in the mold of some soft. The benefit of this is that the battery can be installed in one side so that people in everyday life collection and use of solar energy.

Room for improvement in the traditional solar
Low carbon economy, war, broke out in the world, efficient use of energy, clean energy development is the purpose of developing a low carbon economy, using the development of solar energy to reduce carbon emissions is a major topic in the field, thus promoting the development of renewable energy .
China has become the world's largest producer of photovoltaic cells. Present, the work of thin film photovoltaic solar cells could be divided into the crystalline state by crystallization of thin film-type and non-crystalline thin film type two categories, while the former is further divided into single crystal form and multi-crystalline. Silicon thin film materials can be divided according to type, compound semiconductor thin film and organic film-shaped form.
Solar cells can be divided according to different materials: silicon solar cells, multi-compound thin film solar cells, polymer multilayer modified electrode type solar cell, nano-crystalline solar cells, organic solar cells. Including the development of silicon solar cells is the most mature, dominant in the application.
Currently, the maximum conversion efficiency of silicon solar cells, the most mature technology, but the high cost price, polysilicon thin film silicon solar cells with relatively low cost, and more efficient than amorphous silicon thin film batteries. Low-cost amorphous silicon thin film solar cells, light weight, high efficiency, ease of mass production, but subject to the material effects of a recession triggered by photoelectric efficiency, stability is not high, directly affecting its practical application. Each solar cell can be seen all have different advantages and disadvantages.
In view of this, this is a bottleneck restricting the development of photovoltaic industry where.

Therefore, "micro-flash" set of solar cells in a number of advantages, is bound to lead the PV industry technology, revolutionary change.
In fact, the great potential in the international PV market, driven by competing countries invested heavily in solar cell manufacturing, to expand production, to fight a seat. China Energy Network Editor Shao Lai "China Joint Business Daily" said: "now the world's largest producer of photovoltaic cells, solar cell production in China in 2008 reached 1780MW, accounting for 26% of the global total, for the first time over Germany , highest in the world, although the impact of the global financial crisis, China's PV industry components than stop production or reduced production. However, domestic and international market pull, and policies to promote domestic industry, as well as "micro-flash" the use of new technologies such as solar energy, the solar photovoltaic industry maintained fast growth. "
Solar PV industry continues to develop, technology is also constantly updated, countries holding this banner competed carbon race. "Domestic Investment passion for solar energy photovoltaic industry is still very high. But we must increase research and development of new technology and the quick start the domestic market, China's PV industry to solve 'two out' the embarrassing situation." Shao Li said. Ultimate realization of China's solar energy photovoltaic industry from the "manufacturing country" heading towards "manufacturing power."

Application of solar cells because of its high cost has been hampered, to find a battery can effectively reduce costs, use less material, also has high efficiency. We need to find a new low-cost and efficient solar cells to replace traditional solar cells.
This cell is named "mini flash" not only because of its small size, and it is also used in the manufacturing process is known as a "pick and place device" tool, this tool often used in electronic assembly areas . The tool will be placed in the cell at the bottom of silicon electrical contact elements on it 130 000 times per hour to complete this action. Another light collector is applied to the "micro-flash" device, it is a low-cost, often a device for the lens, the same used in the new solar cells. The use of the device allows the battery to absorb more light into more power. Of course, battery size as small, can be used in the manufacture of short focal length of the light collector, is not only cheap, the results were better.
Great prospect
