Despite recent progress in the process of solar panel production, the production cost of traditional crystalline silicon solar cells will remain high and there is considerable scope for energy and material efficient technologies to uključe.Dominantni process now involves three main steps: 1) treatment of silicon wafers with dopants (usually phosphorous-containing compounds), 2) print / solder metal contacts (silver and aluminum) in the result of light-sensitive plate, and 3) deposition of anti-reflective coating for solar cells (silicon nitride). All procedures require a high temperature regime (furnace). Doping in the first stage usually runs at 800-900 º C and final deposition - to 260 º C, and most of the process subjected to oxygen-free conditions
A few years ago SHARP came up with a new technology based on so-called tandem type silicon thin filmove.Proizvodni process is found to be more environmentally sustainable and energy: new cells can only use 1% of silicon needed for traditional solar panels. These films are mainly prepared chemical vapor deposition without a standard multi-step heat treatment of bulk silicon wafers. Besides the light version, thin-film technology allows stations to be semi-transparent to light. In this way the electricity generating layer can be introduced to Windows, effectively shading from direct sunlight and UV radiation.
thin-film silicon solar panels are expected to expand tremendously energije.SHARP potential for solar manufacturing facility in Japan (Osaka, Sakai Plant) is one of the world's most advanced eco-factory, began operating in 2010. "Super Green Factory "is capable of producing thin-film solar module production to one billion watts of electricity each year. The other two production facilities will be evaluated in Catania, Italy (2011) and based on SHARP UK factory in Wrexham. All buildings contain green principles Design Factory, where attention is paid to the environment in the production of superior products. SHARP thin-film solar panels provide an excellent alternative to traditional power plants, bringing down the cost of solar energy. And we can all benefit from the replacement of coal burners with non-polluting energy sources.
SHARP thin-film technology compared to traditional crystalline silicon solar cells for the .
professional : lower cost and environmental impact, transparent, lightweight, efficiency is less dependent on temperature (works great in hot seasons );
cons . The typical efficiency of around 10% (14% for traditional boards), it comes as glass panels, which are not easily fit into a residential roofing
The total production of solar panels in 2009 was estimated at 9.6 billion watts of capacity, up to 19% from 2008. Silicon thin-film market share of around 5% and is expected to grow by 8-9% in 2010, with total production to 12 billion watts (+ 25% g / g, Dispaybank ).
We believe that it will stimulate the market in 2011-2012.Maloprodajna price for such a panel can reach 2.2 to 2.4 USD / W (maximum capacity). Thus, Sharp solar panels will bring more value to your home and business. Thin-film photovoltaic cells are involved in during his best inventions 2008th
