Prospects of solar LED lights

4-Fiber-Optic-Butterflies-Solar-Lights

LED (Light Emitting Diode), also known as light-emitting diodes, which use solid semiconductor chip as luminescent material, when ends with a positive voltage, the semiconductor carrier compound occurs, release excess energy caused by photon emission produce visible light.
LED Advantages

Energy efficient one thousand hours only a few degrees electricity consumption (60W ordinary incandescent seventeen hours of electricity consumption, ordinary 10W energy-saving lamps one hundred hours of electricity consumption)
Long life light-emitting semiconductor chip, no filament, no glass bulb, afraid of shock, not broken, the service life of up to fifty thousand hours (incandescent life of only one thousand hours, the general energy-saving lamp life of only eight thousand hours)
Healthy light does not contain ultraviolet and infrared light, does not produce radiation (ordinary light contains ultraviolet and infrared)
Green does not contain mercury and xenon and other harmful elements, conducive to recovery and use, and will not produce electromagnetic interference (ordinary lamp contains mercury and lead, elements, energy-saving lamps, electronic ballasts will produce electromagnetic interference)
Protect eyesight DC drive, no strobe (normal lights are AC drive, will inevitably produce strobe)
Light, high efficiency, small heat: 90% of electrical energy into visible light (ordinary incandescent 80% of electric energy into heat, only 20% of electrical energy into light energy)
High safety factor required voltage, current smaller, less heat, no security risk, it can be used in mines and other dangerous places
Market potential and low voltage DC power supply, battery, solar power can be used for outdoor lighting in remote mountainous areas and the lack of electricity, less electricity places.
Reduce costs

In the past the use of silicon as a solar cell material, but also China’s ability to produce silicon is too low, the majority of materials are imported, resulting in the high cost of solar cells. To make solar power a massive scale, scientists must reduce the cost of solar cell materials, or find cheaper solar cell material.
China Photovoltaic Solar Energy Society of Professional Committee director, said Zhao Yuwen, solar cells cost about $ 3.15 / watt, and net system price of $ 6 / watt, power generation cost of $ 0.25 / watt. Preliminary study completed in 8 MW grid-connected PV systems indicate that fully commercial operation of grid-connected PV power tariff of about 3.4 yuan per kilowatt, still unable to compete with thermal power, wind power and the like. But the world of large-scale development of the market and rapid technological advances are enabling PV system equipment and reduce the cost of power generation, photovoltaic systems is expected in 2010 will drop to about $ 3 / watt, power generation costs will fall to $ 0.1 per kilowatt — That is about RMB yuan. He said: “The current cost of thermal power growing up, developing solar electricity can right time.”
Institute of Semiconductors, Min Jin, director revealed that the location of the solar cell research has made a major breakthrough, they use some ‘chemical semiconductor’ materials, greatly improving the photoelectric conversion efficiency; plus the whole system has been carefully integrated in simulated space Under the environment, it is possible to achieve 26% conversion efficiency, and in the ground environment, the conversion efficiency can exceed 30%. Thus, the cost is not an issue, conversion concept is a priority.
Outlook

Several aspects of solar energy experts recently drafted “on the development of the price ladder and promote the development of China’s motion,” draft proposal, one of the drafters, China Photovoltaic Solar Energy Society of Professional Committee executive director Wang Sicheng said: universal “From the amount of resources, distribution , technical reliability, the photovoltaic power generation has more advantages than any other renewable energy sources, the current high cost barriers are as technology advances and mass production is reduced, photovoltaic power generation will become an important component of the future of electricity is It goes without question. “Experts suggest that China should aim to make the 2020 PV cumulative installed capacity reached 30,000 megawatts, photovoltaic power generation capacity will reach 1% of national power generation capacity.
Although this indicator compared with the target in Europe, America, Japan and countries of the gap is still quite large, but in order to achieve this goal, to exclude many obstacles. Experts point out that in many countries, PV has entered the commercial development track; in the desert areas of large-scale grid-connected photovoltaic integration and building a good long-term prospects, is an important part of the renewable energy applications. Global PV industry with more than 30% of the average rate of rapid growth, in 2002 the system output value reached more than 3.5 billion US dollars. States are expected to pull in mitigation actions and policies of industrial development will be further accelerated. China as long as the introduction of appropriate policy, foster standardized size of the market, increase investment, accelerate capacity building, fully qualified Chinese enterprises into the international market relying on the domestic market, to enter the international top ten.
