6 FAQs about [Photovoltaic circuit board cold soldering]
What is a solder interconnection in a PV module?
Solder interconnections perform structural and electrical functions in a PV module. Any degradation in the solder joint means the power generated by the PV cell cannot be accessed. Additionally, the solder joint holds the electrical components (i.e. PV cell, contact and interconnect ribbons) of PV modules together.
What is PV solder joint degradation?
PV solder joint degradation is investigated under European and hot climatic operating temperatures. ANSYS Mechanical package is used to simulate the PV module response to applied loads. Three PV cell temperature ranges with distinct solder joint degradation rates are observed.
What is the relationship between solder degradation and PV cell temperature?
In Region 1 (25–42 °C), the relationship between solder degradation and PV cell temperature is quadratic, and solder degradation rate increased from 1.53 to 10.03 Pa/°C. Region 2 (43–63 °C) is the critical region because the solder degradation rate is highest and constant at 12.06 Pa/°C.
What temperature affects solder joint interconnections in c-Si PV module?
Based on the results and findings of the research, conclusions can be drawn. Elevated operating temperatures in excess of the 25 °C STC accelerates degradation of solder joint interconnections in c-Si PV module. Operations resulting in cell temperature between 43 °C and 63 °C are critical and induce maximum damage in the solder joint.
Are solder joints damaged during thermal cycling?
An investigation of the thermo-mechanical deterioration of the solder joints of PV modules composed of 60 cells was assessed through numerical simulation. The results reveal that during the thermal cycling test, the rear solder is damaged in a much earlier stage than the top solder.
Do high cell and ambient temperatures affect PV solder interconnection reliability?
High cell and ambient temperatures are considered critical to the reliability of PV solder interconnections. This study focuses on hot climates with high ambient temperatures ranging from 25 °C to 45 °C which can force PV cell temperatures to increase to as high as 90 °C.
