Improving the accuracy of temperature coefficient measurement of a PV module by accounting for the transient temperature difference between cell and backsheet

Yogeswara Rao Golive et al.

Summary: Accurate measurement of cell temperature inside a PV module is crucial for Temperature Coefficients (TC) and Current-Voltage (I-V) characteristics. This study records transient temperatures and develops a simulation model to observe temperature profiles. The observed transient temperature difference leads to measurement errors in temperature coefficients, and accounting for this difference improves measurement accuracy.

Degradation analysis of photovoltaic modules after operating for 22 years. A case study with comparisons

L. Lillo-Sanchez et al.

Summary: This study analyzed the degradation of 56 m-Si PV modules exposed outdoors for 22 years in Seville, Spain, with findings of severe browning, milky pattern, and oxidation of the metallization grid as the main defects. The degradation rate was 30.9%, primarily due to a loss in short-circuit current, with lesser impact on fill factor and open circuit voltage.
