Turn the led lamps and lanterns of solar panel manufacturer in efficiency and what factors
For the professional manufacturer of solar panels led mining lamp, conversion efficiency of solar panels is according to the specific products to explain. Not all solar panels are the same, different brand different specifications of the panel is also different. Too
[for specializing in the production of solar energy Solar power ( 太阳能) Can refer to the heat of the sun, See the three ways of heat transmission: radiation) , main show is often said that the sun's rays. 】 Plate led mining lamp manufacturers, solar panels ( Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 The conversion efficiency of the problem is to according to the specific products to explain. Not all of the solar cell' Solar cell is also known as 'solar cells' or 'cell', is a kind of electricity generation by using sunlight directly photoelectric semiconductor wafer. 】 Plate are the same, different brand different specifications of the panel is also different. Solar panels conversion efficiency is obtained with the experiment of the actual energy divided by ideally to calculate the theoretical data, the data is conversion efficiency. Really get electricity/panels on the radiant energy of the sun. 【 series of silicon solar cells, monocrystalline silicon solar cells Monocrystalline silicon solar cells, and is of high purity silicon rods for raw materials of solar cells, and is the fastest development of a solar cell. 】 The highest conversion efficiency, technology is also the most mature. With monocrystalline silicon solar cells do down detailed instructions below:
the photoelectric conversion efficiency of monocrystalline silicon solar cell' The photoelectric conversion efficiency, namely the incident monochromatic photons - Electronic conversion efficiency ( 单色入射光子- - Electron conversion efficiency, abbreviations IPCE) , defined as the unit of time in the internal and external circuit and per unit time the number of the electrons produced can be the ratio of the number of photons incident monochromatic Np. The mathematical expression formula, IPCE = 1240 Isc/( l Pin) Isc, l and Pin, the use of units of mu A cm - respectively 2, the nm and W m - 2. 】 About 15%, the highest of nearly 24%. This is the photoelectric conversion efficiency is highest in all types of solar cells, but the production cost is very big, so that it can't be extensive and widespread use. Due to the commonly used single crystal silicon [toughened glass Toughened glass ( 钢化玻璃/增强玻璃) Surface with compressive stress of the glass. 】 And waterproof resin encapsulation, so its durable, generally can amount to 15 years, the service life of up to 25 years.
ordinary solar cells are generally in the battery cell voltage reaches 0. 4 to 0. 6 v output maximum power. In standard conditions (rizhao 1000 watts per square meter) , 1 square meters of solar panels on the output of electric power for 130 to 180 watts, photoelectric conversion efficiency of 13% to 18% on average.
the solar cell is using the principle of photoelectric conversion to the radiation of the sun light through the semiconductor material into a device of electric power and the photoelectric conversion process is usually called the photovoltaic effect & throughout; , so the solar cell is also known as photovoltaic cells throughout the &; 。 Amorphous silicon solar cells with high conversion efficiency, also but instability in its material determines its application is not very wide. Questions about the conversion efficiency of solar panels is here, if the customer and other similar or different related questions, can consult us, we will sincerely waiting for you to solve all kinds of difficulty!
