Building integrated photovoltaics

Acronym of BIPV (Building Integrated Photovoltaics) refers to photovoltaic systems integrated with an object's building phase. They are built along with an object such as buildings. Yet they could be built later for sure.

Due to specific task cooperation of many different experts, such as architects, civil engineers and PV system designers, is necessary. According to how and where such systems are built, whether into the facade or in the roof, the following BIPV systems are recognized:

• Facade or roof systems added after the building was built
• Facade integrated photovoltaic systems built along with an object
• Roof-integrated photovoltaic systems built along with an object
• "Shadow-Voltaic" - PV systems also used as shadowing systems, built along with an object or added later

Solar Cells Sale In China

Today the Chinese Solar industry has seen rapid growth ever. According to 2007 Deep Research Report on China Solar cell industry，2006 China Solar Cell Shipment was 400.9 W，Increased 237.74% than 118.7MW in 2005，and reached 1021.5 MW in 2007 estimatively，increased 154.8% than 2006.

About the revenue: 2006 China Solar Cell revenue was 1251.4 Million USD，Increased 264.5% than 343.3 Million USD in 2005，and est. reached 3188.6 Million USD in 2007，increased 154.8% than 2006.

About utilization: the total solar cell utilization of China is 27.36 in 2005, 34.24% in 2006, about 41.61% in 2007, est. 76.99 in 2012; the low utilization during 2005 and 2006 mainly because the following two reasons: first, the expansion of solar cell manufacture capacity is fast; second, the shortage of solar cell raw material(wafer or polysilicon) is tremendous.

In this blog we dedicated to provide you with the updated information about the booming solar cell market.

Solar power generation technology is founded upon silicon, a common element that comprises approximately 25% of the earth’s crust by mass. When light falls on high purity silicon, the PV (photovoltaic) effect causes the release of electrons from the silicon atoms. When silicon is fashioned into a solar cell with collection electrodes, the PV effect generates an electrical current.

Solar cells are produced from raw silicon materials in a multistage process. Firstly raw quartzite sand is processed into bulk silicon, which is subsequently melted and formed into blocks or ‘ingots’. The ingots are cut and sliced to produce ‘wafers’ which form the basis of a solar cell. Solar cell manufacturers add electrodes to the wafer for electrical connectivity. The wafers are then cleaned and treated prior to their introduction into the manufacturing process.

The increased awareness on renewable energy and climate change has led to demand of solar power elements outstripping supply with Government subsidies and falling costs and prices continuing to support the industry growth. Many companies had already begun to produce massive solar cells to fulfill the thirsty market.
