This enabled the team to calculate how different device designs with textures at various interfaces affect efficiency. "Based on these complex simulations and empirical data, we believe that an efficiency of 32.5 % can realistically be achieved -- if we succeed to incorporate high quality perovskites with a band gap of 1.66 eV," says Jošt.
