We fabricated monolithic solid state modules based on organometal CH 3 NH 3 PbI 3 and CH 3 NH 3 PbI 3 − x Cl x perovskites using poly‐(3‐hexylthiophene) and Spiro‐OMeTAD as hole transport materials (HTMs). In particular, we developed innovative and scalable patterning procedures to minimize the series resistance at the integrated series‐interconnections. By using these optimization steps, we reached a maximum conversion efficiency of 8.2% under AM1.5G at 1 Sun illumination conditions using the CH 3 NH 3 PbI 3 − x Cl x perovskite and the poly‐(3‐hexylthiophene) as HTM. Finally, we investigated the double‐step deposition of CH 3 NH 3 PbI 3 using the Spiro‐OMeTAD, reaching a maximum conversion efficiency on active area (10.08 cm 2 ) equal to 13.0% (9.1% on aperture area) under AM1.5G at 1 Sun illumination conditions. This remarkable result represents the highest PCE value reached for the perovskite solar modules. Copyright © 2014 John Wiley & Sons, Ltd. Monolithic perovskite photovoltaic modules have been fabricated by using both single‐step and double‐step deposition methods. Optimized laser patterning procedure has been introduced to improve cell interconnections. A record efficiency of 13% on a 10.08 cm 2 active area has been achieved by using Spiro‐OMeTAD as hole transport layer.
