According to iSuppli Corporation, thin-film solar cells are rapidly capture Laptop Battery market share in crystal technology have been, to 2013, the PV part of more than double the number of watts. By 2013, solar panels in the global market, the efficiency of thin film from 2008 of 14% to 31%.
"FirstSolar already showing strong evidence of the viability of thin-film market, the company jumped this year, the world's largest manufacturer of solar panels, yield more than one billion watts." ISuppli's research director GregSheppard said, "At the same time, the company has already produced per watt the cost down to less than 90 cents a silicon crystal is about half of the module manufacturer. "
Crystal and thin-film
Most solar panels made from crystalline silicon, using 180-230 micron polysilicon. On the contrary, thin-film panels through the deposition of multi-layer Hp Omnibook XT1500 battery substrate made of other materials, the thickness of a few microns. The main difference between the two technologies lies in the efficiency and cost of electricity per watt. Thin-film panel in the sunlight into electricity less efficient, but its production costs are significantly lower.
It is noteworthy that the film in the installation space is limited at a disadvantage, such as residential roofing. Film installation may need more space to account for 15-40% of the crystalline silicon to achieve the same with the overall system power output. This tends to limit its activities in certain application areas more attractive.
Price comparison
Thin-film modules are expected next year, the Hp Omnibook XT1000 battery average price will drop to 1.40 U.S. dollars, 1.70 dollars lower than in 2009. In 2010 the average price of crystalline silicon panels are expected to fall to 2.00 dollars, 2.50 U.S. dollars this year.
iSuppli Corporation predicts that by 2012, crystalline silicon will to a certain extent, to narrow the price gap, because its suppliers are financially strong, they continue in capital expenditures, technology development and has invested heavily in improving production processes.
iSuppli, the global thin-film solar cell production, and crystal technology, the proportion of forecasts.
Variety of thin film technology
There are a variety of thin-film photovoltaic technology. They are mostly less than 10% efficiency, although some technology can be Hp Pavilion ZT1100 battery efficient through experiments up to the middle class. Some of these technologies are referred to as a single node, using a diode. Recent developments in the use of multiple nodes with each other superimposed together, also known as tandem and three knots, so by using different materials or combinations wider absorption spectrum of knot.
Most of these techniques rely on chemical vapor deposition (CVD), or derived from the screen printing process, the layers of material deposited on different substrates, namely glass and various plastics. Some of the recent use of inkjet printing technology, like ways to more quickly deposited materials.
Promote the accelerated development of thin film technology, another factor is the use of materials,Hp Pavilion XZ200 battery companies such as Oerlikon, and to provide more Centrotherm package production lines.
