We have developed superstrates for perovskite solar cells that feature increased transparency and conductivity due to the incorporation of effectively transparent contacts (ETCs). They increase the short-circuit current density by more than 1 mA/cm2 compared to standard indium tin oxide (ITO) on glass superstrates. These ETC superstrates are composed of sodalime glass with a thin ( \sim 40 \mu \mathrm {m}) layer of polydimethylsiloxane (PDMS) that features triangular cross-section microscale grooves, which are infilled with a conductive silver ink and subsequently coated by a thin ( \sim 30 nm) ITO layer such that high lateral conductivity ( < 5 \Omega /sq) is achieved without altering the surface properties of standard perovskite superstrates.
