The temperature of the photovoltaic cell and the irradiance are measured simultaneously with the I-V characteristics. The accuracy of the temperature measurement is ±0.5°C, and the accuracy of the irradiance is ±3 W/m 2.
This work was supported by a grant of the Romanian National Authority for Scientific Research and Innovation, CNCS, UEFISCDI, Project no. PN-II-RU-TE-2014-4-1083 and Contract no. 135/1.10.2015. The temperature is one of the most important factors which affect the performance of the photovoltaic cells and panels along with the irradiance.
In , the authors indicate that increasing the PV cell temperature by 10 °C results in a 4% energy loss. For this reason, accurate knowledge of the photovoltaic cell temperature is essential for the correct prediction of the energy produced . In the literature, different models have been suggested for predicting PV cell temperature.
The absolute and normalized temperature coefficients are determined and compared with their values from the related literature. The variation of the absolute temperature coefficient function of the irradiance and its significance to accurately determine the important parameters of the photovoltaic cells are also presented.
where p represents the parameter of the photovoltaic cell and T is the temperature. The dependence of the photovoltaic cell parameter function of the temperature is approximately linear [ 21 ], and thus, the temperature coefficients of the parameters can be determined experimentally using the linear regression method [ 22 ].
This study reports the influence of the temperature and the irradiance on the important parameters of four commercial photovoltaic cell types: monocrystalline silicon—mSi, polycrystalline silicon—pSi, amorphous silicon—aSi, and multijunction InGaP/InGaAs/Ge (Emcore).
