Description
Wang and co-authors report a materials study, published in 2026, on steering crystal growth in a class of layered solar cell materials. These perovskite films are stable, but their crystals often lie flat, which blocks the flow of charges and caps efficiency. The team laid down thin layers of two small organic acids on the film's base. The acids grip both the base layer and the growing crystals with two anchor points each. That grip templates the crystals to grow upright instead.
One acid worked best, aligning in an ordered way that guided the film's growth. Upright crystals let charges travel straight to the contacts. The treated films thus promise higher efficiency without losing the family's stability edge. The authors frame interface design as the lever. Two well-placed molecular anchors, they show, can organize a whole film.
