From the motion of the hydrogen ions
from energy used in light.
The energy to make NADPH in the light reactions of photosynthesis comes from sunlight. Light energy is absorbed by chlorophyll molecules in the chloroplasts of plant cells, which triggers a series of reactions that ultimately produce NADPH.
From electrons in photosystem I that are excited to a higher energy state by photons of light. Then NADP + is reduced to become NADPH
Light is absorbed where it is converted into energy via the light reactions. It is then transfered to the Calvin Cycle, where it is used to make stored energy, and the used ATP (energy) units are recycled to the light reactions and the process repeats.

Photosystem 1
ATP is produced from the light reactions, which is then coupled with the light independent reactions. NADPH is also produced, but its job is to carry electrons which eventually make ATP.

Light-independent reactions
Sources of energy that can make matter emit light include heat energy (thermal radiation), electrical energy (electric discharge), and chemical energy (luminescence from chemical reactions).
