Firstly

four experiments were conducted to assess the properties of acetic acid-resistant ethylene-vinyl acetate copolymer（EVA） film： acid concentration test

high temperature stripping test

volume resistivity test

and electroluminescence（EL） test of small double-glass modules encapsulated with a combination of acetic acid-resistant EVA and ethylene vinyl acetate/polyolefin elastomer（EPE）. Secondly

the reliability of N-type TOPCon solar cells' double-glass photovoltaic modules——encapsulated with acetic acid-resistant EVA and EPE

conventional EPE and EPE

as well as combinations of acetic acid-resistant EVA and EVA——is meticulously examined. The results indicate that the acetic acid concentration in acetic acid-resistant EVA is lower than that in conventional EVA after the PCT test. Furthermore

there is no significant black discoloration observed due to corrosion on the small modules' EL after both the PCT144 h and DH1000 h tests. This suggests that acetic acid-resistant EVA exhibits minimal corrosion effects on TOPCon solar cells under these conditions. The volume resistivity of acetic acid-resistant EVA exceeds 10 Ω·cm

thereby meeting the insulation requirements for photovoltaic （PV） modules. The acetic acid-resistant EVA exhibits a stable adhesion to glass at a temperature of 80 ℃

thereby mitigating the risk of delamination under high-temperature conditions. The power degradation of double-glass PV modules encapsulated by acetic acid-resistant EPE and EVA combination and double EPE combination is less than 4% after DH3000 h

PID288 h and TC600 test

which can meet the International Electrotechnical Commission（IEC） standard. Therefore

the combination of acetic acid-resistant EPE and EVA can be utilized to encapsulate double-glass modules

serving as a replacement for the conventional EPE and EVA combination. This approach effectively meets the demand for encapsulation film particles while contributing to cost reduction.
