IBM develops a high power concentrating photovoltaic solar cell system
 |
Recently, a research team of IBM has developed a high-efficiency cooling heat utilization type high-power concentrating photovoltaic solar cell system (hereinafter referred to as HCPVT) that combines photovoltaic power generation and solar heat utilization. The HCPVT system has a pot-shaped sunlight acceptance surface of 40 square meters. A 36-sided oval mirror was installed to collect light, and multi-junction solar cells and coolers (for heat exchange) were installed at the spot. The system can collect 2000 times of the amount of sunlight per unit area. The R&D team claimed to be ensuring On the premise of security, this data can also be refreshed to 5,000 times.
The system produces water as it absorbs sunlight and can be used to make filtered drinking water or as a heat source for absorption chillers. Scientists believe that the HCPVT system can provide sustainable energy and fresh water for all communities around the world.
In a sunny area (8 hours of light per day), each 1*1 cm photovoltaic chip can convert 200-250 watts of energy on average. In order to ensure cooling of the equipment, within the HCPVT system, water at 90 degrees Celsius will pass through the porous membrane distillation system. During this water cooling process, the cooling water will be vaporized and vaporized until it is desalted into fresh water. The system's unit sunlight receiving area (one square meter) can produce 30-40 liters of drinkable fresh water per day, in addition to generating 2 kilowatt hours of electricity per day. The large-scale HCPVT system can bring enough freshwater supplies to small towns.
The heat energy in the system will be absorbed by hundreds of tiny solar photovoltaic chips. When energy is obtained, it will be cooled by the water in the thin tubes to ensure that the system can safely perform high-power condenser operations.
Greenpeace said the technology ranks third in renewable energy. A 2009 study predicts that solar energy can meet global energy needs with minimal footprint. Greenpeace expects to use 2% of the Sahara desert area to supply a global supply of electricity.
The main drawback of today's solar power generation technology is that the energy conversion rate is very low. Most of the useful heat energy is wasted and cannot be used. It is a pity that solar panels absorb a lot of sunlight and are exposed to high temperature melting safety hazards. HCPVT The system completely solved this problem.
It is understood that the HCPVT project has been funded by the Swiss Technology and Innovation Commission. Developers can receive 2.4 million U.S. dollars in funding in three years. At present, product prototypes have been made and are in the testing phase.
This free technology program to meet global energy needs will be met with a counterattack by the oil giant Jedi, but the power of the people is endless. The R&D staff plans to commercialize in 2017 to provide sufficient energy and fresh water for homes, medical facilities and commercial facilities in sunny areas.
