Recently, hybrid lead halide perovskite have revolutionized the photovoltaic research at the laboratory scale, mainly due to the relative low-cost techniques required to fabricate perovskite-based solar cells (PSC) and their outstanding photoconversion efficiency (PCE); which approaches comparable values to the silicon technology (≈20 %) [1]. Despite the promising results obtained so far and the encouraging future expectations, several issues and limitations must be overcome in order to make PSC a competitive and convenient technology for the development of high performance large-scale solar panels. The most commonly configuration of PSC consist of the use of FTO and Au as contacts, and TiO2 and Spiro-OMeTAD as electron and hole selecting layer, respectively. In this scenario, different research groups are describing new architectures, including inverted,[2] semi-transparent sandwich PSC[3] and tandem devices with Si technology.[4] In this communication, we report our most recent results in the development of PSC with flexible fabrication procedures for alternative configurations.
