Balancing structural formability and lattice microstrain in methylammonium-free wide bandgap perovskites

JPhys Energy
State-of-the-art wide bandgap perovskite compositions for perovskite/silicon tandem solar cells often incorporate methylammonium (MA) containing multi-cation-mixed-halides compositions to achieve high efficiency.

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, EarlyView.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

Investigation of perovskite layer growth from solution on textured substrates

EPJ Photovoltaics
Surface textures are indispensable to minimize optical losses in perovskite-based solar cells. However, the solution-processing of perovskite layers is often not compatible with textured substrates, and little is known about the film growth thereon. This

Basic understanding of perovskite solar cells and passivation mechanism

AIP Advances, 2022
Although perovskite solar cells (PSCs) have made great achievements during the past few years, the efficiency of PSCs is only up to 25.5%, which is comparable to silicon-based solar cells.
