Why is solar spectral intensity per wavelength different than solar spectral intensity per frequency?

If I have understood you question correctly
... ( it didn't have much supporting info) ....
I would suggest because frequency and wavelength are inversely proportional.....

increase freq. decrease wavelength and visa versa

If that isn't what you are looking for, then make your Q a bit easier to understand

Why the shape of the curve is different when the intensity is plotted in a graph against frequency and against wavelength? That is your question?

Shortly, because the relationship between frequency and wavelength is non-linear, indeed they are inversely proportional. You might read this insight:
