China's thin-film solar cell industry

Since 2003, crystalline silicon Solar Cells the main raw material polysilicon prices have risen 10 times, from the original 20 U.S. dollars / kg soaring to nearly 300 U.S. dollars / kg. In the raw materials, a "rise in the price", it naturally turning to the industry's raw material consumption of silicon and crystalline silicon solar cells is only 1% of the amorphous silicon thin-film solar cells. Like all new industries, China's thin-film solar cell industry will face in the development process, "Growing Pains" and must get past a number of difficulties.

Photoelectric conversion efficiency to be increased. Compared with the crystalline silicon solar cells, despite the thin-film solar cells have no doubt that the cost advantage, but its 5% -8% of the photoelectric conversion efficiency of crystalline silicon solar cells less than 1 / 2, through technological breakthroughs in order to enhance the photoelectric conversion thin-film cell efficiency is a major issue. Of course, the size of thin-film solar cell production conditions are ripe for research and development work can be established on the basis of industrialization, which advances in technology will undoubtedly be helpful.

Manufacturing equipment controlled by foreign companies. In recent years, the domestic in the crystalline silicon solar cell manufacturing equipment, the field of rapid development, but the thin-film solar cell equipment market continues to be the United States Applied Materials, ULVAC, Japan and Switzerland, Oerlikon carved up by three companies. Thin-film solar cell industry, China should also be concerned about the development of equipment manufacturing industry.

The high price of the entire PV industry needs to face. At present solar thermal electricity price is 10 times. Some experts pointed out that with the increase in costs of environmental protection, thermal electricity price change will show a rising curve, while the thin-film solar cells with the electricity price will be a large-scale production and conversion efficiency gradually decreased, the two curves is expected to in the intersection between the years 2012 -2015.

Market prospects are also not to be ignored. Crystalline silicon solar cell industry in China is characterized by a "two out", that is the main raw material producing areas and the major markets abroad. Even if the thin-film solar cell industry to alleviate problems of raw materials, it can not avoid the risk of excessive dependence on international markets.

NonUniformities in ThinFilm Solar Cells and Modules $157.72 Thinfilm PV technology due to its fast production line, large area panels and low material usage, is one of the most promising lowcost technologies. Due to their granular structure, thinfilm solar cells are inherently nonuniform. Fluctuations inevitably occur during the multistep deposition process of large area thinfilm solar panels and specific manufacturing procedures. Furthermore, non uniformities can become more severe, or increase in size during the solarpanels life cycle. Non uniformities reduce the overall efficiency of solar cells and modules, and their effects therefore need to be well understood. This manuscript focuses on the analysis of the effect of nonuniformities on small size solar cells and modules with the help of numerical simulations. Even though the 2D model developed here can analyze the effect of nonuniformities of any nature, only two specific types of microscopic nonuniformities were addressed here: shunts and weakdiodes. One type of macroscopic nonuniformity, partial shading, was also addressed. The circuit model developed here is a network of diodes, currentsources, and transparentconductiveoxide resistors.

Solar Shingles $90.81 High Quality Content by WIKIPEDIA articles Solar shingles, also called photovoltaic shingles, are photovoltaic cells designed to look like conventional asphalt shingles. There are several varieties of solar shingles, including shinglesized solid panels that take the place of a number of conventional shingles in a strip, semirigid designs containing several silicon solar cells that are sized more like conventional shingles, and newer systems using various thin film solar cell technologies that match conventional shingles both in size and flexibility. Solar shingles are manufactured by companies including SunPower Corporation, Solar Components Corporation, Atlantis Energy Systems, and Dow Chemical.

Manifold Microchannel Cooling of Photovoltaic Cells $111.53 Several works have been published on concentration of solar radiation by mirrors or lenses onto smaller size solar panels, which reduce cost and increase conversion efficiency at higher concentration ratio. One of the challenges is active and uniform cooling of high heat flux solar arrays, because conversion efficiency is dependent on device temperatures and drops with increasing temperature. This research is targeted at cooling of small, high concentrated solar cells. Benefits of manifold microchannel are attractive for cooling of electronic devices but have not been studied for cooling of high concentrated solar cells which is the objective of this research, where the microchannel can be microfabricated and etched on the backside of the silicon solar cell to form a sealed heat sink with the manifold fabricated in the silicon substrate. This design not only minimizes the pressure drop, but also maximizes the heat transfer and provides uniform temperature across the device.
