Abstract 2, 2′, 7, 7′‐tetrakis‐(N, N‐di‐4‐methoxyphenylamino)‐9, 9′‐spirobifluorene
(spiro‐MeOTAD) hole transport material (HTM) is a milestone in the history of perovskite …

With the application of organic–inorganic hybrid perovskites to liquid‐type solar cells, the
unprecedented development of perovskite solar cells (Per‐SCs) has been boosted by the …

The development of low-cost and efficient hole transport materials (HTMs) is important for
the commercialization of perovskite solar cells (PSCs). Comparing with the widely studied …

Hole transport materials (HTMs) are a key component of perovskite solar cells (PSCs). The
small molecular 2, 2′, 7, 7′‐tetrakis (N, N‐di‐p‐methoxyphenyl)‐amine‐9, 9 …

Perovskite solar cells have delivered power conversion efficiency beyond 22% in less than
seven years, implying the potential for the paradigm shift of low‐cost photovoltaics with high …

The exploration of alternative low-cost molecular hole-transporting materials (HTMs) for both
highly efficient and stable perovskite solar cells (PSCs) is a relatively new research area …

In the last few years, organic–inorganic halide perovskites (OIHP) have gained significant
attention in the optoelectronics community and become one of the most popular research …

The use of expensive hole transporting materials (HTMs), such as spiro-OMeTAD, in
perovskite solar cells (PSCs) is one of the critical bottlenecks to hinder their large-scale …

We have designed and synthesized fluorinated indolo [3, 2-b] indole (IDID) derivatives as
crystalline hole-transporting materials (HTM) for perovskite solar cells. The fluorinated IDID …

Perovskite solar cells have become one of the most promising technologies to make use of
solar energy; to date, the power conversion efficiencies (PCEs) have been improved from …
