Solar garden lights can thin-film batteries is introduced

The introduction of thin-film solar cell amorphous silicon solar cell is a new type of thin film type solar cell in 1976 to present, it has to do with monocrystalline silicon and polycrystalline silicon solar cell production way completely differences, process simplified, require little silicon material, lower power consumption, its main



the introduction of thin-film solar cells

amorphous silicon solar cell' Amorphous silicon solar cell is through the photoelectric effect or photochemical effect turn light energy into electrical energy device. 】 Was present in 1976 new thin-film solar cell' Solar cells can effectively absorb solar energy and convert it into a power semiconductor components. 】 It with monocrystalline silicon 【 Silicon single crystal. 】 And polycrystalline silicon solar cell' One of the solar cell. 】 Production way completely differences, the process simplified, require little silicon material, lower power consumption, its main advantage is in low light conditions can also generate electricity. But the amorphous silicon solar cell is the main problems the photoelectric conversion efficiency is low, the current international advanced level of 10% at the mercy, and not the same, with time delay, the attenuation of conversion efficiency. The thin film photovoltaic cells' Solar photovoltaic cells ( Photovoltaic cells) For the sun's light energy into electrical energy directly. 】 According to the material can be divided into three categories: silicon thin-film batteries, compound semiconductor thin film batteries, dye sensitized photochemical photovoltaic cells. The silicon in the 【 By expert team building of industrial ceramics, the silicon in engineering materials co. , LTD in jiangsu, new product test platform, the new equipment test platform, the theory and engineering research and development center. 】 Base thin-film batteries mainly include: amorphous silicon thin film, film micro crystal silicon, polycrystalline silicon thin film. Admittedly thin-film batteries in the international commercial photovoltaic cells produce and the proportion of small, zhongshan new energy co. , LTD. Is engaged in the production design the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Solar street lamp, the high lamp factory, 20 years production experience, to build the most professional manufacturer of solar street lamps,. , but efficient battery will ultimately go thin film technology route. The thin layer and p - N junction in the form of the layout of the thin-film batteries, can achieve 40% ~ 50% or more of the photoelectric conversion efficiency.
