Solar panels, how to delay the recession of solar power

Zhongshan solar panels - Guangdong energy technology co. , LTD. The so-called light attenuation refers to the sun to lead to battery power decline phenomenon. Solar panels, photovoltaic modules to light attenuation can be divided into two stages: initial light aging and decay.

The light of the solar panels, photovoltaic modules to attenuation can be divided into two stages: initial light aging and decay. 1. Initial attenuation to the initial light attenuation, namely the output power of solar panels, pv modules in the use of a significant reduction in the first few days, but then stabilise. This kind of phenomenon is the main reason of the P type ( Boron doping) The boron - crystal silicon wafers Oxygen compound reduces the minority carrier lifetime. By changing the P type dopant and grain instead of boron, can effectively reduce the light attenuation. Or to light treatment, the cell makes the battery of the initial light attenuation occurs before the module manufacturing, pv modules can be the initial light attenuation control within the scope of the small, also improves the output stability of the module. Photoinduced attenuation is more related to the battery manufacturers, and for components manufacturer, it is important to choose the high quality batteries to reduce the influence of photoinduced attenuation. 2. Aging aging decay refers to power down very slowly in the long-term use. Main reasons related to battery slow attenuation and the packaging material performance degradation. Ultraviolet radiation is the main reason leads to the deterioration of the main components of the performance. Long-term exposure to the sun's ultraviolet rays to EVA and the back ( The structure of TPE) Ageing yellow, resulting in a decline in component light transmittance, thus resulting in a decline in power. This requires components manufacturers should strictly controlled, when choose EVA and the back material chosen must have excellent aging resistance, in order to reduce auxiliary components of power attenuation caused by material aging.
