Exploration of charge transport materials to improve the radiation tolerance of lead halide perovskite solar cells

“…Lang et al reported that PVK/PVK tandem solar cells retain over 94% of their initial PCE after irradiation at a dose of 10 13 protons cm À2 (68 keV), 36 while III-V solar cells exhibit a decrease in their PCE by more than 22%. 39 PSCs exhibit high radiation tolerance to many types of radiation, such as from protons, 40 electrons, 30,41 ion beams, 42,43 neutrons, 44 and g-rays. 45,46 In contrast, PSCs undergo degradation during EB-induced current measurements, which indicates their sensitivity to EB irradiation-induced phenomena.…”

Electron Beam Irradiation of Lead Halide Perovskite Solar Cells: Dedoping of Organic Hole Transport Materials despite Hardness of the Perovskite Layer

“…Miyazawa et al reported the superior radiation tolerance of MAPbI 3 and MA 0.15 FA 0.85 PbI 2.55 Br 0.45 , whereby devices survived a dose of up to 10 16 electrons cm –2 (1 MeV) and 10 15 protons cm –2 (50 keV), which are doses at which c-Si and III-V solar cells are completely destroyed . Other reports also showed the robustness of perovskite against protons, , ion beams, , neutrons, and γ-rays. , These excellent features along with the high power-per-weight performance make PSC plausible candidates for use in space satellites and rockets . In contrast, Klein-Kedem et al have pointed out the relatively low thermal stability of perovskites when exposed to intense EB in microscopy and spectroscopy .…”

Radiation-Resistant CsPbBr3 Nanoplate-Based Lasers

“…There have been some irradiation tests of perovskites under different kinds of radiation particles at reference energies, for example, electrons (∼1.5 keV to 1 MeV), 30−32 protons (∼50 keV to 68 MeV), 31−35 neutrons (>10 MeV), 36 MeV), 37,38 and ions (Ga + : ∼30 keV, He + : 3 MeV, etc.). 39,40 These irradiation tests were almost based on the perovskite solar cells and demonstrated that the perovskite solar cells possessed superior radiation resistance than crystalline Si-and GaAs-based solar cells. Nonetheless, the stability of perovskite material itself and its related lasing properties under irradiation have been rarely studied.…”
