Enhanced long-term stability of perovskite solar cells using a double-layer hole transport material

Author affiliations

Abstract

The instability of hybrid organic–inorganic perovskite solar cells hinders their commercialization and further applications although they have reached high power conversion efficiency. Here we introduce a double-layer hole transport material into perovskite solar cells containing a CuSCN layer and spiro-OMeTAD layer simultaneously. Consequently, the long-term stability of the solar cells was significantly enhanced compared to those of single-layer devices and the devices can sustain about 90% of their initial power conversion efficiency after 10 hours of continuous working at the maximum power point. We ascribed the long-term stability enhancement to the suppression of methylamine migration by the CuSCN layer.
