The use of a non-volatile additive 4-hydroxybenzylamine to suppress non-radiative recombination, a three-step deposition strategy enabling thick lower-bandgap middle absorber, and low-refractive-index SiOx-nanoparticles acting as an optical middle reflector together enable the manufacture of perovskite–perovskite–silicon triple-junction solar cells with a certified efficiency of 30.02%.
