Solar panel composition structure and the transformation effect light pole quotation rate analysis

Silicon solar panels, silicon reserves is extremely rich, the power conversion rate and service life is relatively good, so it became the most solar panels application of semiconductor materials; In addition to the silicon and inorganic salt ( Scenery complementary street lamps such as arsenic



solar panel' Solar cell is also known as 'solar cells' or 'cell', is a kind of electricity generation by using sunlight directly photoelectric semiconductor wafer. 】 Silicon, silicon reserves is extremely rich, the power conversion rate and service life is relatively good, so it became the 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. 】 Most used semiconductor material; In addition to the silicon and inorganic salt ( Scenery complementary street lamp' The reasonable application of new energy street light - - MUCE scenery complementary street light after years of efforts, the new energy street light has been more and more people are recognized and applied, a thriving market situation. 】 Such as gallium arsenide 【 Gallium arsenide ( 砷化镓) The chemical formula of GaAs. 】 III【 British regiment Take That III is the seventh studio album. 】 - V compounds, cadmium sulfide 【 There are two kinds of cadmium sulfide, crystal, alpha Type a lemon yellow powder, beta Type are orange powder. 】 Than, copper indium selenium compounds) , polymer, nanocrystalline 【 Nanocrystals using high energy aggregation sphere, the water calcium and magnesium ions, packaged produce insoluble in water, such as bicarbonate nanoscale crystals, so that the water will not scale to achieve the purpose of softening. 】 For materials such as solar cells.

the current mainstream of photovoltaic cells' Solar photovoltaic cells ( Photovoltaic cells) For the sun's light energy into electrical energy directly. 】 Crystalline silicon material is 【 Crystalline silicon materials is the main photovoltaic materials, properties of colored solid with a metallic luster, high melting point ( 1410). And chemical properties of high hardness, brittleness, room temperature not lively. 】 , the preparation of crystalline silicon thin silicon wafers is very fragile, so we usually see photovoltaic panels 【 Photovoltaic panels, also known as Solar panels Solar panel, is made up of a number of Solar battery components installed in a certain way on a piece of plate assembly, usually as a unit of photovoltaic phalanx. 】 Is assembled by a variety of structure.

solar panels solar panels conversion efficiency

there are many factors that can affect the electrical conversion efficiency of solar panels. For different batteries, influence factors include: the semiconductor materials, light intensity, production process; For the same cell, the influence factors include: the battery structure, characteristics, material properties, working temperature, the radioactive particle radiation damage and environmental changes, etc. The current photoelectric conversion efficiency of 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. 】
