A network of Silver Nanowires (AgNWs) sandwiched between titanium oxide (TiO2) films fabricated by solution-process was applied as electron conductor in MAPbI(x)Cl(3-x)-based perovskite solar cell. This network can prevent the formation of space limited charge existing between perovskite and AgNWs. As a result, a high performance of 12.55% was achieved, with a short circuit current density of 19.35 mA/cm(2), an open circuit voltage of 0.94 V and a fill factor of 0.69. We investigated the charge separation and transport properties. Compared to the other two situations (the pristine TiO2 compact films and TiO2 with AgNWs as a top layer), the incorporation of TiO2/AgNWs/TiO2 films led to lower leakage current density, smaller series resistance, more smooth surface coverage and larger recombination resistance. This explains the improved J(sc), and FF obtained for the perovskite solar cell with TiO2-AgNWs (embedded). (C) 2016 Elsevier Ltd. All rights reserved.
