The team exploited this interaction by engineering a polymer containing a halogen iodine atom and ferrocene, an active redox ...
Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means ‘salt former’.
The researchers found that the the introduction of their pseudo-halogen thiocyanate ions into iodine/bromide mixed halide perovskites prevented halide elements from separating inside the solar cells.
The three common Group 7 elements are chlorine, bromine and iodine. The word ‘halogen’ means 'salt former'. Group 0 and testing ions Flame tests identify alkali metal ions in compounds.
