Vertically oriented low-dimensional perovskites for high-efficiency wide band gap perovskite solar cells

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-10 (2024)

Abstract Controlling crystal growth alignment in low-dimensional perovskites (LDPs) for solar cells has been a persistent challenge, especially for low-n LDPs (n 1.7 eV) impeding charge flow. Here we overcome such transport limits by inducing vertica

Sublimed C60 for efficient and repeatable perovskite-based solar cells

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-10 (2024)

Abstract Thermally evaporated C60 is a near-ubiquitous electron transport layer in state-of-the-art p–i–n perovskite-based solar cells. As perovskite photovoltaic technologies are moving toward industrialization, batch-to-batch reproducibility of

Enhanced optical path and electron diffusion length enable high-efficiency perovskite tandems

Autor: Bin Chen, Se-Woong Baek, Yi Hou, Erkan Aydin, Michele De Bastiani, Benjamin Scheffel, Andrew Proppe, Ziru Huang, Mingyang Wei, Ya-Kun Wang, Eui-Hyuk Jung, Thomas G. Allen, Emmanuel Van Kerschaver, F. Pelayo García de Arquer, Makhsud I. Saidaminov, Sjoerd Hoogland, Stefaan De Wolf, Edward H. Sargent

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-9 (2020)

Metal-halide perovskite based tandem solar cells are appealing but making a high efficiency device is not trivial. Here Chen et al. increase the carrier collection in the perovskite layer and largely enhance the efficiency in tandem cells when combin

Potassium Thiocyanate‐Assisted Enhancement of Slot‐Die‐Coated Perovskite Films for High‐Performance Solar Cells

Autor: Fuzong Xu, Jiang Liu, Anand S. Subbiah, Wenzhu Liu, Jingxuan Kang, George T. Harrison, Xinbo Yang, Furkan H. Isikgor, Erkan Aydin, Michele De Bastiani, Stefaan De Wolf

Publikováno v: Small Science, Vol 1, Iss 5, Pp n/a-n/a (2021)

Slot‐die coating is highly promising for scaled deposition of metal halide perovskite thin films. However, the power conversion efficiencies (PCEs) of slot‐die‐prepared perovskite solar cells (PSCs) still lag behind their spin‐casted counterp
