Metal-oxide-based charge-transport layers have played a pivotal role in the progress of
perovskite solar cells. Yet metal-oxide/perovskite interfaces are often highly defective, owing …

Perovskite solar cells (PSCs) have made incredibly fast progress in the past years, with the
efficiency approaching 26%, which is comparable to those of the best silicon solar cells. One …

Controlling the perovskite morphology and defects at the buried perovskite-substrate
interface is challenging for inverted perovskite solar cells. In this work, we report an …

Improved stability and efficiency of two-terminal monolithic perovskite-silicon tandem solar
cells will require reductions in recombination losses. By combining a triple-halide perovskite …

The open-circuit voltage (V OC) deficit in perovskite solar cells is greater in wide-bandgap
(over 1.7 eV) cells than in perovskites of roughly 1.5 eV (refs.,). Quasi-Fermi-level-splitting …

The performance of perovskite solar cells with inverted polarity (pin) is still limited by
recombination at their electron extraction interface, which also lowers the power conversion …

Record power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have been
obtained with the organic hole transporter 2, 2′, 7, 7′-tetrakis (N, N-di-p-methoxyphenyl …

Perovskite solar cells (PSCs) based on the regular n–i–p device architecture have reached
above 25% certified efficiency with continuously reported improvements in recent years. A …

Organic semiconductors have become essential parts of thin-film electronic devices,
particularly as hole transport layers (HTLs) in perovskite solar cells (PSCs) where they …

Perovskite solar cells (PSCs) have attracted much attention due to their low-cost fabrication
and high power conversion efficiency (PCE). However, the long-term stability issues of PSCs …
