      abstract     = {The performance of tandem organic solar cells (OSCs) is
                      directly related to the functionality and reliability of the
                      interconnecting layer (ICL). However, it is a challenge to
                      develop a fully functional ICL for reliable and reproducible
                      fabrication of solution-processed tandem OSCs with minimized
                      optical and electrical losses, in particular for being
                      compatible with various state- of-the-art photoactive
                      materials. Although various ICLs have been developed to
                      realize tandem OSCs with impressively high performance,
                      their reliability, reproducibility, and generic
                      applicability are rarely analyzed and reported so far, which
                      restricts the progress and widespread adoption of tandem
                      OSCs. In this work, a robust and fully functional ICL is
                      developed by incorporating a hydrolyzed silane crosslinker,
                      (3-glycidyloxypropyl)trimethoxysilane (GOPS), into
                      poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)
                      (PEDOT:PSS), and its functionality for reliable and
                      reproducible fabrication of tandem OSCs based on various
                      photoactive materials is validated. The cross-linked ICL can
                      successfully protect the bottom active layer against
                      penetration of high boiling point solvents during device
                      fabrication, which widely broadens the solvent selection for
                      processing photoactive materials with high quality and
                      reliability, providing a great opportunity to continuously
                      develop the tandem OSCs towards future large-scale
                      production and commercialization.},
