Hybrid perovskites show potential for space solar cells, with MAPbI3, FAPbBr3, and FAPbI3 exhibiting low energy transfer. Mixed cation perovskites offer enhanced radiation resistance against proton flux.
Area of Science:
- Materials Science
- Solid State Physics
- Renewable Energy
Background:
- Hybrid perovskites are promising for solar cell applications.
- Understanding their response to radiation is crucial for space deployment.
Purpose of the Study:
- To evaluate the ionization, displacement, and heating effects of proton irradiation on hybrid perovskites.
- To identify perovskite compositions suitable for radiation-rich environments like space.
Main Methods:
- Numerical simulations using SRIM (Stopping and Range of Ions in Matter) and SCAPS (Solar Cell Capacitance Simulator) were employed.
- Calculations considered proton energies of 0.15, 3.0, and 18 MeV.
Main Results:
- MAPbI3, FAPbBr3, and FAPbI3 showed the lowest energy transfer, indicating high potential for space solar cells.
- Perovskites with mixed cations (FA, Cs) demonstrated superior stability against vacancy and phonon formation, showing promise as radiation-resistant materials.
- Proton energy deposition was found to be uniform across the solar cell depth and area at MeV energies.
Conclusions:
- Specific hybrid perovskite compositions are well-suited for space solar cell applications due to their radiation tolerance.
- Simple plastic film shielding is effective against low-energy protons, while mixed-cation formulations enhance resistance to higher fluxes.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation...
