Metal‐halide perovskites are rapidly emerging as an important class of photovoltaic
absorbers that may enable high‐performance solar cells at affordable cost. Thanks to the …

Kesterite‐based solar cells are attracting considerable attention in recent years, owing to the
reduced toxicity and greater abundance of their constituent elements. In this brief review, we …

In this work, we report the benefits of incorporating phenethylammonium cation (PEA+) into
(HC (NH2) 2PbI3) 0.85 (CH3NH3PbBr3) 0.15 perovskite for the first time. After adding small …

The past 2 years have seen the uniquely rapid emergence of a new class of solar cell based
on mixed organic–inorganic halide perovskite. Grain boundaries are present in …

As a low‐cost substitute that uses no expensive rare‐earth elements for the high‐efficiency
Cu (In, Ga)(S, Se) 2 solar cell, the Cu2ZnSn (S, Se) 4 (CZTSSe) solar cell has borrowed …

Grain boundaries (GBs) play an important role in organic–inorganic halide perovskite solar
cells, which have generally been recognized as a new class of materials for photovoltaic …

This work provides a detailed analysis of a high efficiency Cu2ZnSnSe4 device using a
combination of advanced electron microscopy and spectroscopy techniques. In particular, a …

As an alternative to single crystal silicon photovoltaics, thin film solar cells have been
extensively explored for miniaturized cost-effective photovoltaic systems. Though the fight to …

In this research, a new route of surface passivation is reported by introducing hydrogen from
the atomic layer deposited (ALD) Al2O3 layer into pure sulfide Cu2ZnSnS4 (CZTS) solar …

HC (NH2) 2PbI3 perovskite solar cells have emerged as a promising alternative to
CH3NH3PbI3 perovskite solar cells due to their better thermal stability and lower bandgap …
