Although　perovskite　has　great　potential　in　optoelectronic　devices,　the　simultaneous　satisfaction　of　material　stability　and　high　performance　is　still　an　issue　that　needs　to　be　solved.　Most　perovskite　optoelectronic　devices　use　quantum　dot　spin　coating　or　the　gas-phase　growth　of　perovskite　thin　films　as　the　photoelectric　conversion　layer.　Due　to　stability　limitations,　these　materials　often　experience　a　significant　decrease　in　photoelectric　conversion　efficiency　when　encountering　liquid　reagents.　The　self-assembled　growth　of　hybrid　perovskite　crystals　determines　superior　lattice　ordering　and　stability.　There　are　three　types　of　ionic　liquids-[Emim]BF4,　EMIMNTF2,　and　HMITFSI-that　can　effectively　enhance　the　X-ray　photoelectric　conversion　performance　of　hybrid　perovskite　crystal　CH3NH3PbI3　(MAPbI(3)),　and　the　enhancement　in　the　photocurrent　leads　to　an　improvement　in　the　sensitivity　of　X-ray　detectors.　We　soak　the　perovskite　crystals　in　an　ionic　liquid　and　perform　two　treatment　methods:　electrification　and　dilution　with　ETOH　solution.　It　is　interesting　to　find　that　MAPbI(3)　perovskite　single　crystal　materials　choose　the　same　optimized　ionic　liquid　species　in　X-ray　detection　and　photovoltaic　power　generation　applications,　and　the　effect　is　quite　the　opposite.　Compared　with　untreated　MAPbI(3)　crystals,　the　average　photocurrent　density　of　Electrify-HMITFSI　MAPbI(3)　increased　by　826.85%　under　X-ray　excitation　and　the　sensitivity　of　X-ray　detectors　made　from　these　treated　MAPbI(3)　crystals　significantly　increased　by　72.6%,　but　the　intensity　of　the　PL　spectrum　decreased　to　90%　of　the　untreated　intensity.
