Also, standard environmental tests, specified under IEC 61215 were found to induce finger and interconnect D & D like in field, however, defect specific tests may be devised for a detailed ...
Study shows n-type bifacial TOPCon cells more prone to degradation than p-type
All encapsulants were tested according to the IEC 61215 PV standard and beyond, with extended testing time. According to the research group, the testing showed that hydrophobic and chemically inert TPO encapsulants provided the highest degree of protection against moisture-induced degradation compared to EVA and POE.
