      abstract     = {The unprecedented rise in efficiency of perovskite-based
                      photovoltaics has sparked interest in semi-transparent
                      devices, particularly for tandem structures. Despite
                      promising reports regarding efficiency and reduced parasitic
                      absorption, many devices still rely on processes from the
                      gas phase, compromising both applicability and cost factors.
                      Here, we report all-solution perovskite solar cells with
                      improved infrared transparency ideally suited as top-cells
                      for efficient multi-junction device configurations. We
                      demonstrate the functionality of copper(I) thiocyanate as
                      antireflective layer and as selective contact between the
                      transparent conductive oxide and the perovskite. This
                      concept allows us to fabricate an opaque device with steady
                      state efficiency as high as $20.1\%.$ By employing silver
                      nanowires with robust environmental stability as the bottom
                      electrode, we demonstrate different regimes of device
                      performance that can be described through a classical
                      percolation model, leading to semi-transparent solar cells
                      with efficiencies of up to $17.1\%.$ In conjunction with the
                      implementation of an infrared-tuned transparent conductive
                      oxide contact deposited on UV-fused silica, we show a full
                      device average transmittance surpassing $84\%$ between 800
                      and 1100 nm (as opposed to $77\%$ with PEDOT:PSS as the
                      selective contact). Finally, we mechanically stacked
                      optimized perovskite devices on top of high performing PERL
                      and IBC silicon architectures. The measured imputed output
                      efficiency of the 4-terminal perovskite–silicon solar cell
                      was $26.7\%$ and $25.2\%$ for the PERL–perovskite and
                      IBC–perovskite, respectively.},
