In this work, we explore the underlying reasons for scaling losses of perovskite solar cells, especially for the p-i-n configuration, and have successfully reduced this scaling loss to ~0.9%. With a comprehensive understanding of the underlying mechanisms, high-quality PSCs with a PCE of 20.3% for 2 cm2 devices and 19.8% for 6.8 cm2 mini-modules were obtained.

This study, which takes place in Advanced Materials Technologies, demonstrates PLD‐grown IZRO transparent electrode on semi‐transparent perovskite solar cells.

In this publication, which took place in Nature Energy, we investigate the influence of scattered and reflected light from the ground (albedo) on the performance of the bifacial tandems with different perovskite bandgaps.

This study, which took place in JPCC, demonstrates the correlation between the Urbach energy of perovskite absorbers and open-circuit voltage deficiency at the solar cell level.

This paper, published in Materials Horizons, reviews the state-of-the-art recombination junction which has been used for perovskite-based tandems and explains the fundamental working principles behind it.

This study, which took place in Nature Energy, show that a lower bandgap perovskite than needed at standard test conditions is actually beneficial to perovskite/silicon tandem cells in the field.

This study, published in ACS Energy Letters, reports one of the highest PCE for single-junction devices fabricated by lost die coating as well as showing the first example of slot-die coated perovskite/silicon tandems on textured interfaces.

Areej's in situ plasma approach offers excellent thickness control and superior structural integrity upon thermal annealing at 1000 °C. This study, which gives implied open‐circuit voltage exceeding 700 mV published in Advanced Materials Interfaces.

This study demonstrates improved performance and stability via in-house synthesized organic cyano‐based π‐conjugated molecules. Kai Wang's this passivation study came out in Advanced Functional Materials.

This study, which came out in the recent issue of ACS Applied Materials & Interfaces, successfully demonstrates the Lewis-acid (TPFB) doping of the widely used spiro-OMeTAD hole transport materials for perovskite solar cells to. This dopant replaces the conventional LiTFSI/tBP doping. By doing so, the device stability is increased and processing is simplified.

This study, which develops a strategy to circumvent the problem of boron diffusion into the silicon, took place in the recent issue of Advanced Materials Interfaces. This study is the first publication KPV-LAB in the field of poly‐Si passivating contact solar cells.

This work, published in Solar RRL,  presents a detailed study of the photophysics of multiple‐cation mixed halide lead perovskites and develops a concise picture of the impact of cesium/rubidium incorporation on the photophysics and device performance.

This study, published in Joule, reports 23.9%-efficient 6-in silicon heterojunction solar cells with improved damp-heat-stability for aiming the mass production.

This study shows 28.2% lab-scale mechanically stacked perovskite/silicon tandem solar cells in collaboration with Sargent Group from the University of Toronto - published in Nature Communications
