Abstract

The ability to process amorphous or polycrystalline solar cells at low temperature (<150 °C) opens many possibilities for substrate choice and monolithic multijunction solar cell fabrication. Organometal trihalide perovskite solar cells have evolved rapidly over the last two years, and the CH3NH3PbX3 (X= Cl, I or Br) material is processed at low temperature. Until now however, the most efficient solar cells have employed 500 ºC sintered TiO2 compact layers as charge selective contacts. With our optimized formulation we demonstrate full sun solar power conversion efficiencies exceeding 16 % in an all low temperature processed solar cell.
