Promising tin based perovskite are being developed. This addresses the disposal issue. Also chemical stability is being addressed in many ways, some of which more promising than others. Single crystal perovskites are extremely promising because they lack the defects present in polycrystalline and these defects are usually the origin of chemical instability. Also 2D perovskites are another way to address chemical instability and currently have been steadily increasing in overall efficiency. Sorry I don’t have sources for u, I’m too lazy to get them cause I typed this on my phones… but good reviews on each of these topics are one google away!
