POLYMER/INORGANIC HOLE TRANSPORT LAYER FOR LOW-TEMPERATURE-PROCESSED PEROVSKITE SOLAR CELLS

P3HTCuSCN 1

ABSTRACT

In the work we introduce a hysteresis-free low-temperature planar PSC, composed of a poly (3-hexylthiophene)(P3HT)/CuSCN bilayer as a hole transport layer (HTL) and a mixed cation perovskite absorber. Proper adjustment of the precursor concentration and thickness of the HTL led to a homogeneous and dense HTL on the perovskite layer. This strategy not only eliminated the hysteresis of the photocurrent, but also permitted power conversion efficiencies exceeding 15.3%. The P3HT/CuSCN bilayer strategy markedly improved the life span and stability of the non-encapsulated PSCs under atmospheric conditions and accelerated thermal stress. The device retained more than 80% of its initial efficiency after 100 h (60% after 500 h) of continuous thermal stress under ambient conditions.
