Inputs are in the other answer, and since you asked I'll give the outputs:
glucose (for the plant - created by the Calvin Cycle [through the input of Carbon dioxide]) and oxygen (which the plant does not require, so it exits the plant - created through the water input)
If you want to get really technical, the input light is absorbed and its energy is used to drive electrons from the water. These electrons generate NADPH, which drives protons across the membrane. The protons will then return to make ATP (which is through ATP synthase). (There are some good diagrams of this you could find on the internet for a better visual if needed, but since they aren't mine, I feel I should not post them)
In terms of inputs, outputs and energy transformations, photosynthesis can be summarized as follows. Inputs - Sunlight as energy source, carbon dioxide and water. Processes - Chlorophyll traps sunlight; the energy is used to split water molecules; hydrogen from water is combined with carbon dioxide to produce glucose.
