“…1,2 In long-term environmentally exposed Si PV modules, however, it is known that acetic acid is formed from the EVA encapsulant by a hydrolysis reaction. 3,4 Formation of acetic acid was also observed in the modules aer long-term damp-heat (DH) tests under high temperature with high humidity. This is supposed to be one of predominant degradation processes of crystalline Si PV modules in addition to the delamination of the EVA encapsulant.…”

Potential-induced degradation (PID) in p-type-based multicrystalline Si photovoltaic (PV) modules was experimentally generated applying À1000 V from an Al plate, which is attached on the front cover glass of the module, to the Si cell at 85 C for 2 h. The solar energy-to-electricity conversion efficiency (h) of the standard Si PV module significantly decreased after the PID test. In contrast, no degradation was observed in the modules, including a thin polyethylene (PE) film (30 mm thickness) with the copolymer of ethylene and vinyl acetate (EVA) as the encapsulant. It was suggested that the PE film whose volume resistivity is higher than that of EVA prevented the diffusion of Na + from the front cover glass toward the Si cell, resulting in a suppression of PID because different degradation processes during PID were observed in the EL images for the two modules, including a half PE film. In addition, the Si PV module, including a PE film, demonstrated stable performance after a damp-heat test (85 C/85% relative humidity) for 4000 h, although the h of the standard module significantly decreased from 16.0% to 7.6% after the test. Our results indicate an attractive and promising low-cost technique for improving the long-term stability of crystalline Si PV modules against potential and damp-heat-induced degradation.

“…Although PV systems are considered dependable in the field, with minimal degradation and failure rates, [5][6][7][8] they are vulnerable to numerous significant failure mechanisms such as corrosion and delamination. [9][10][11][12] Recently, PID in PV modules has become significant among the evident reliability problems, since it has the potential to cause the catastrophic failure of PV modules in outdoor environments. Generally, module frames in gridconnected PV systems are grounded for safety, and solar panels are often connected in series to increase the voltage output.…”

“…Among the various solutions for cheaper fabrication is the utilization of new materials or approaches in solder connection technology, including the use of high performance electronic products such as flip-chip binding, 11) ball grid arrays, 12) and photovoltaic (PV) module encapsulation, 13) which can help address this issue of electrical power loss due to poor bonding strength. However, the production cost of PV module encapsulation in solder connections is still too high when using silver paste as the electrical interconnects between solar cells and copper strips.…”

In this study we deposited Sn-3.0Ag-0.5Cu solder alloy as a bonding material in lead-free soldering by utilizing inkjet printing to improve the electrical interconnections of solar cell modules. Sn-3.0Ag-0.5Cu solder was successfully printed to bond thin-film solar cell modules. The improved interface wetting behavior between the adhesive surface of the aluminum electrode and lead-free solder joints in silicon thin-film solar cell modules was investigated with respect to reflowing at 240°C for 30 s by using an optical microscope and mean contact angle. The results show that the peel strength of the Sn-3.0Ag-0.5Cu solder alloy is better than that of silver paste when the dot spacing of solder droplets is lower than 200 µm (a density of over 50 µg/mm 2 ). The findings also show that the contact resistance of the solder alloy is better than that of silver paste when the dot spacing of solder droplets is lower than 100 µm. This results in a low power loss of solar cells of 1.1%, and a good photovoltaic conversion efficiency of over 8.3%. This study thus demonstrates the feasibility of decreasing the efficiency loss of solar cells by employing the proper spacing of lead-free solder droplets by inkjet printing.
