For any given temperature, the ni X ni = constant?

Let's write n
i2(T). When you write p1 X n1 = ni X ni and then p2 X n2 = ni X ni, you've lost the temperature dependence.
p(T) X n(T) = n
i2(T) always.
Quote: When a p type Silicon(with dopant 10e17) is excite by light, the
electron concentration n(initial) will increase to some n(excite)
value.
Is it true that n(initial) X 10e17 = ni X ni
then n(excite) X 10e17 = ni X ni
No, that's not right, because that would imply n(initial) = n(excite).
Start with p(T) X n(T) = n
i2(T)
Initially, n(T) = n(initial) and p(T) = 10e17.
After excitation, n(T) = n(excite), but p(T) = ?
