Hole‐transporting layers (HTLs) are an essential component in inverted, p–i–n perovskite
solar cells (PSCs) where they play a decisive role in extraction and transport of holes …

Since 2009, perovskite solar cells (PSCs) have witnessed dramatic developments with the
record power conversion efficiency (PCE) exceeding 25% within a single decade. One …

Tandem solar cells that pair silicon with a metal halide perovskite are a promising option for
surpassing the single-cell efficiency limit. We report a monolithic perovskite/silicon tandem …

This review article discusses the current designs and synthetic procedures for organic small
molecules as hole-transporting materials (HTMs) with a focus on their structure–property …

Organic–inorganic hybrid perovskite solar cells (HPSCs) have achieved an impressive
power conversion efficiency (PCE) of 25.2% in 2019. At this stage, it is of paramount …

Long-term durability is critically important for the commercialization of perovskite solar cells
(PSCs). The ionic character of the perovskite and the hydrophilicity of commonly used …

The rapid rise of perovskite solar cells (PSCs) is increasingly limited by the available charge-
selective contacts. This work introduces two new hole-selective contacts for p–i–n PSCs that …

Alpha and gamma-alumina are materials used as continuous coatings and also in various
fields such as ceramics, catalysis and catalytic support, lubricants, and electronics. Boehmite …

Hole‐transporting materials (HTMs) play a critical role in realizing efficient and stable
perovskite solar cells (PVSCs). Considering their capability of enabling PVSCs with good …

There has been considerable progress over the last decade in development of the
perovskite solar cells (PSCs), with reported performances now surpassing 25.2% power …
