photovoltaic panel is to use the light of the semiconductor interface will born v effect in a technology light energy directly into electrical energy. Mainly by the solar cell' Solar cells can effectively absorb solar energy and convert it into a power semiconductor components. 】 Plate ( Components) , controller and inverter Inverter is the direct current (dc) can ( Batteries, battery) Converted into alternating current (ac) ( General is 220 v, 50 hz sine wave) 。 】 Three major part, main part is composed of electronic components. 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. 】 After a series of packaging protection can form a large area of solar cell components, combined with power controller and other components are formed on the photovoltaic device. Photovoltaic power generation is the main principle of the photoelectric effect of the semiconductor. Photons illuminate to metal, its energy can be absorbed by all metal in an electronic, electronic absorption energy is enough big, can overcome the metal internal gravity work, left to escape from a metal surface, become a photoelectron. Silicon atoms have four outer electrons, if in the pure silicon doped with five outer electrons of the atoms such as phosphorous, becomes the n-type semiconductor 【 Also known as electronic semicoductor. 】 ; If in the pure silicon doped with three outer electrons of the atoms such as boron atoms, forming p-type semiconductor 【 P type semiconductor, also known as hole type semiconductor. 】 。 When the P and N together, contact surface will form a potential difference, become a solar cell. When the sun to the p-n junction, hole from N to P polar polar mobile, electronic consists of N to P polar polar mobile, a current.
photovoltaic panel effect is the uneven illumination semiconductor or generate an electrical potential difference between different parts of the semiconductor and metal combination. It is first and foremost by the photon ( Light waves) Into electronic process, the light energy into electrical energy; Secondly, the forming process of voltage. Photovoltaic principle diagram of polysilicon through ingot casting, broken pieces, slice, procedure, made for processing wafers. On silicon doping and diffusion trace amounts of boron, phosphorus, etc. , forming a p-n junction. Then use silk screen printing, will be fine with good silver paste printed on silicon gate line, after sintering, made back electrode at the same time, and in a grid line surface coated with a layer of antireflection coating on the cell is made at this point. Battery slice of permutation and combination into components, it is made up of a large circuit board. Generally around the component package aluminum frame, front cover glass, negative electrode installation. A battery components and other auxiliary equipment, can be composed of power systems. In order to direct current into alternating current (ac), need to install the current converter 【 Current converter ( convertor) Refers to converting a signal into another signal of the device. 】 。 After power storage battery are available, and also can enter the public grid. Cost of power generation system, battery components accounted for about 50%, current transformer, installation expenses and other accessories and other fees accounted for another 50%. Household photovoltaic power station 【 Photovoltaic power station, is a use of solar energy panels, the use of special materials such as silicon, composed of electronic components such as inverter power generation system, connected to the grid and sending electricity to the grid photovoltaic power generation systems. 】
