Abstract

An important challenge in the commercialization of perovskite solar cells (PSCs) is the simultaneous attainment of high power conversion efficiency (PCE) and high stability. Using polymer interfaces in PSCs can enhance durability by blocking water and oxygen and by suppressing ion interdiffusion, but their electronic shielding poses a challenge for efficient and stable PSCs1–3. Here we report a magnetic endohedral metallofullerene Nd@C82–polymer coupling layer, which features ultrafast electron extraction and in situ encapsulation, thereby promoting homogeneous electron extraction and suppressing ion interdiffusion. The Nd@C82–polymer coupling layer in PSCs exhibited a PCE of 26.78% (certified 26.29%) and 23.08% with an aperture area of 0.08 cm2 and 16 cm2 (modules), respectively. The unencapsulated devices retained about 82% of the initial PCE after 2,500 h of continuous 1-sun maximum power point operation at 65 °C.
