To understand degradation routes and improve the stability of perovskite solar cells (PSCs),
accelerated aging tests are needed. Here, we use elevated temperatures (up to 110° C) to …

The dominated hole transport material (HTM) used in state-of-the-art perovskite solar cells
(PSCs) is Spiro-OMeTAD, which needs to be doped to improve its conductivity and mobility …

Perovskite solar cells (PSCs) have rapidly emerged as one of the hottest topics in the
photovoltaics community owing to their high power‐conversion efficiencies (PCE), and the …

Dopant‐free organic hole transport materials (HTMs) remain highly desirable for stable and
efficient n‐i‐p perovskite solar cells (pero‐SCs) but rarely succeed. Here, we propose a …

Metal halide perovskites are the first solution processed semiconductors that can compete in
their functionality with conventional semiconductors, such as silicon. Over the past several …

Rapid progress in the efficiency of hybrid lead halide perovskite photovoltaics surpassed the
semiconductor thin-film solar cells such as CdTe (cadmium telluride), CZTS (copper zinc tin …

Developing dopant‐free hole transport materials (HTMs) to replace Spiro‐OMeTAD is a
challenging but urgent issue for commercialization of state‐of‐the‐art n‐i‐p structured …

The present pin perovskite solar cells are less efficient than their nip counterparts,
fundamentally limited by deep-level traps of minority carriers at surfaces. Here, we explore …
