WebMay 4, 2024 · Herein, the use of µ-graphene (µGR) to crosslink QDs to form µGR/CsPbI 3 film is demonstrated. It is found that the resultant QDs film provides not only an effective channel for carrier transport, as witnessed by much improved conductivity but also significantly better stability against moisture, humidity, and high temperature stresses. WebRoom-temperature films of black-phase cesium lead iodide (CsPbI3) are widely thought to be trapped in a cubic perovskite polymorph. Here, we challenge this assumption. ... + Graphene Flagship More from this funder. Funding agency for: Giustino, F. Grant: Horizon2024 696656 Graphene Core 1
