Ensuring the customer is protected from excessive power loss, means they can be sure of the higher output power under radiation in the early period of panel use and the stability in production of PERC technology These benefits are of course in addition to REC’s industry-leading product quality,along with the reliability of a strong and established The conversion efficiency of silicon-based solar cells and panels is sensitive to temperature and will vary with changes in the working temperature. The temperature coefficient (TC) is the amount by which
the PMPP will change depending on the temperature the panel is exposed to. In a solar panel,the parameter that is most affected by an increase in temperature is open circuit voltage where dark saturation current density is highly temperature dependent. On the other hand,the short circuit current of a solar cell generally increases slightly with temperature due to the possibility of absorbing photons with lower energies to create electron hole pairs; the effect of this is however small compared to the temperature dependence of open circuit voltage.
