Over the last years, interest for organolead trihalide perovskite materials (ABX3 where A is an ammonium cation, B a metal cation and X an halide) as light absorber in solar cells has increased continuously [1]. One of the most studied hybrid perovskite material is methylammonium lead triiodide (MAPbI3) leading to 15 to 20% efficiencies in a FTO/TiO2/mp-TiO2/MAPbI3/Au structure [2,3]. A new method for preparation and one-step process deposition of the perovskite material [4] is here used in a planar heterojunction FTO/compact-TiO2/MAPbI3/HTM/Au structure leading to 11% efficiency (on 0.28 cm² cell) when Spiro-MeOTAD is used as HTM (J/V curve Figure 1 (left)). Five new spiro-based HTM (Figure 1 (right)) are then compared to this reference system.
