Abstract

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/cm^2 compared to standard indium tin oxide (ITO) on glass superstrates. These ETC superstrates are composed of sodalime glass with a thin (∼40μm) 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 (∼30 nm) ITO layer such that high lateral conductivity (<5Ω/sq) is achieved without altering the surface properties of standard perovskite superstrates.
