“…[ 30 ] Global internet constellations on low earth orbits and in the vicinity [ 31,32 ] are the fastest growing market segment for space photovoltaics in the coming decade approaching gigawatt (GW) installations. [ 33 ] However, space hardware will be exposed to proton radiation on these orbits. Therefore, it is of great interest to evaluate radiation stability for PSCs.…”

The drastic reduction in launch and manufacturing costs of space hardware has facilitated the emergence of "commercial" space. Radiation-hard organometal halide perovskite solar cells (PSCs) with low-cost and high-efficiency potentials are promising for space applications.High-efficiency PSCs are tested with different hole transport materials (HTMs) and dopants on 175μm sapphire substrates under 7MeV-proton-irradiation-tests at accumulated fluences of 10 11 , 10 12 , and 10 13 protons cm −2 . While all cells retain >90% of their initial power conversion efficiencies (PCEs) after 10 11 protons cm −2 irradiation, PSCs that have tris( pentafluorophenyl)borane (TPFB) as the HTM dopant and poly[bis(4-phenyl)(2,5,6-trimethylphenyl) amine (PTAA) or PTAA:C8BTBT (C8BTBT = 2,7-Dioctyl[1]benzothieno[3,2-b][1]benzothiophene) as the HTM are more tolerant to higher-fluence radiation than their counterparts with the lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) dopant and the 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (Spiro-OMeTAD) HTM. Radiation induces fluorine diffusion from the LiTFSI dopant toward the perovskite absorber (confirmed by depth-resolved X-ray photoelectron spectroscopy) introducing defects. Radiation-induced defects in cells with the TPFB dopant instead are different and can be "annealed out" by thermal vacuum resulting in PCE recovery. This is the first report using thermal admittance spectroscopy and deep-level transient spectroscopy for defect analyses on proton-irradiated and thermal-vacuum-recovered PSCs. The insights generated are expected to contribute to efforts in developing low-cost light-weight solar cells for space applications.

“…Perovskite solar cells are promising for terrestrial energy production, which opens new opportunities for low‐cost space power, due to their high specific power and appropriate spectrum response. [ 61 ] A comprehensive analysis [ 62 ] also pointed out a massive cost reduction of $10–$20 billion USD if perovskite PV (instead of the conventional GaAs PV) is used in the expanding low earth orbit (LEO) satellites market. However, delivering on these promises will require overcoming lots of environmental challenges associated with the space environment.…”

High-quality perovskite film is deposited on a 30 cm × 40 cm LiCoO 2 -coated ITO/glass via newly developed freely falling anti-solvent extraction (FFASE) method followed by post watervapor annealing in an ambient atmosphere. Perovskite solar modules (PSMs, active area of 25.2 cm 2 with mask) based on this high-quality film achieve the highest efficiency of 16.04 and 30.76% under 1 sun (100 mW cm −2 ) and 945 lux fluorescent light illumination, respectively. The encapsulated PSMs are stable at −20 to 80 °C thermal cycling and keep high efficiency at temperature as low as −20 °C and as high as 80 °C. When the encapsulated PSM is heated at 85 °C and 85% relative humidity under room lighting or heated at 60 °C under AM1.5 (100 mW cm −2 ) illumination for 1000 h, loses only ≈8% of its original efficiency. The high stability of PSMs is due to very high quality perovskite absorber being used. The underlying concept of the FFASE method for extracting the solvent from the large-area perovskite precursor film is that the whole precursor film contacts with the fresh anti-solvent during the crystallization stage.

“…In contrast, exible single-junction PSCs can reach an impressive ratio of 23-29 W g −1 , while multijunction PSCs can surpass even that, reaching an outstanding ratio of 79-83 W g −1 . 13,14 Based on the above comparison, the PSCs are undoubtedly better suited to meet the needs of spacecra for lightweight energy systems. However, the longterm stability of PSCs remains the main obstacle to their pragmatic applications.…”
