Abstract
The next generation medical imaging will benefit significantly from artificial intelligence - therefore, not only advances in computing power are required, but also further materials and technology improvements will lead to better image quality. The strong X-ray absorption, high charge carrier mobility and lifetime recommend perovskites like methylammonium lead triiodide (MAPbI3) as novel direct X-ray converting materials. A major obstacle to the commercialization is the limited stability and lifetime, as reported until now. Here, we show for the first time that degradation is limited in our X-ray detector after 1.5 years of storage in ambient conditions.
