For photochemical reactions, you should know the following reactions:
Reduction of Silver(I) Bromide, which is the basis of Photography. A photographic film is coated with it's layer, and when it is exposed to sunlight, silver ions accept electrons from Bromide ions and form Silver atoms. Ag+ + e- ---> Ag (colour change is from white to black.

the second one is Photosynthesis:
This should not be a problem if you take Bio.
Sunlight is trapped by the green pigements (chloroplasts) in the cholorophyll. This is photochemical because it only occurs in sunlight and is totally dependent on sunlight.

Good Luck
