Standard state problem of I-V characteristic test of photovoltaic glass solar cells

It can be revised according to the following standards: GB/T? 6495.4- 1996 temperature and irradiance correction method for I-V measured characteristics of crystalline silicon photovoltaic devices?

Footprint 1 in the figure below represents the measured data value, and Footprint 2 represents the desired data, such as the standard state you want (T2=25℃). For photovoltaic modules, the temperature coefficients of voltage and current are known, so for the first formula, α is known, while T 1 is the field temperature (measurable), ISR is the current of standard cells under standard conditions (measurable), IMR is the measured current of standard solar cells, and Isc is the short-circuit current of module samples (measurable), so I2 can be obtained. Similarly, according to the second formula, V2 can be obtained from I2.

GB/T？ The standard of 6495.4- 1996 can be found in Baidu Library. If necessary, you can leave an email address for communication.
