Photovoltaic panel manufacturers cell why rural solar street lights will

Solar photovoltaic panel manufacturer after the component has been produced, tested the power, the power component is normal, but the customer receives the components, install and operate, it found that the power attenuation is bigger.

solar photovoltaic panel manufacturer after the component has been produced, tested the power, the power component is normal, but the customer receives the components, install and operate, it found that the power attenuation is bigger. This phenomenon is mostly caused by battery patches of light cause attenuation. Why should there be light attenuation 【 cell Light attenuation, the correct statement is that the energy of the photon attenuation. 】 Phenomenon?

photovoltaic panel manufacturers photovoltaic modules' Monomer solar cells cannot be used directly do the power. 】 To light attenuation can be divided into two stages: the initial light aging and decay. 1) Initial attenuation to light: light attenuation, namely the output power of pv modules in the first use of significantly decline occurs in the first few days, but then stabilise. Cause of the main reasons for this phenomenon is P type ( Boron) Boron oxide in crystalline silicon complex reduces the life of Jane. By changing the p-type doping agent, use the standing grain instead of the boron can effectively reduce the light to decay; Or to light treatment, the cell is the cell of the initial light attenuation to happen before component manufacturing, photovoltaic modules of the initial cause attenuation can control in a small scope, but also improve the output stability of components; 2) Aging decay, aging attenuation refers to the use for a long time in extremely slow power decrease, the main reason about battery slow attenuation, are also associated with packaging material performance degradation. One led to the when the irradiation of ultraviolet light component advocate material of the main causes of performance degradation. Long-term exposure to the sun's ultraviolet rays, make what street lamps like EVA 【 Eva can refer to an evangelion anime series, can also refer to Eva all the body. 】 And the back ( TPE【 TPE（ 热塑性弹性体) Is a kind of thermoplastic elastomer material, high strength, high elasticres ilience, injection molding processing characteristics, application scope is widespread, environmental non-toxic safety, have excellent coloring. 】 Structure) Degradation and yellowing phenomenon, resulting in a decline in component light transmittance, resulting in power down.
