Bismuth-based halide perovskite and perovskite-inspired light absorbing materials for photovoltaics

Feray unlu et al.

Summary: The efficiency of perovskite solar cells has increased significantly in the past decade, showing great promise for the next generation of solar cells. However, concerns about the adverse effects of lead on health and the environment have hindered their commercialization. This review focuses on the development of lead-free perovskite materials, particularly bismuth-based perovskites, which have shown enhanced stability under ambient conditions.

3,5-Difluorophenylboronic acid-modified SnO2 as ETLs for perovskite solar cells: PCE > 22.3%, T82 > 3000 h

Jiajia Zhang et al.

Summary: By modifying SnO2 with FPBA, the trap state density of SnO2 was significantly reduced and better energy-level alignment was achieved, leading to an increased power conversion efficiency of perovskite solar cells. Additionally, the FPBA-modified SnO2-based unencapsulated device showed good stability with over 82% of initial PCE retained after long-term storage.

Influence of Inorganic NiOx Hole Transport Layer on the Growth of CsBi3I10 Perovskite Films for Photovoltaic Applications

Pandiyarajan Mariyappan et al.

Summary: In this study, spray pyrolysis processed nickel oxide was utilized as a hole transport layer for bismuth halide perovskite-based inverted planar perovskite solar cells. The use of nickel oxide HTL improved the crystallinity of the perovskite layer and reduced the energy-level mismatch at the interface between the perovskite and HTL. The PSCs fabricated with nickel oxide as HTL showed a power conversion efficiency of 0.72% and maintained 85% of its initial efficiency value even after 100 hours of light soaking.

Implementing an intermittent spin-coating strategy to enable bottom-up crystallization in layered halide perovskites

Yajie Yan et al.

Summary: The random orientation of layered crystals in 2D perovskites impedes the out-of-plane carriers transport and hence undermines the photovoltaic performance. Here, the authors discover that the crystallization can be regulated by intermittent spin-coating strategy, significantly enhancing crystal orientation and carrier transport, leading to a substantial improvement in solar cell efficiency.
