The light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts, specifically in the grana. The grana are stacks of thylakoid membranes where the light-dependent reactions take place. The stroma, on the other hand, is the fluid-filled space surrounding the grana where the Calvin cycle (light-independent reactions) occurs. So, the light-dependent reactions primarily occur in the grana, not the stroma.

stroma
The spaces between grana in a chloroplast are called stroma. Stroma is where the enzymes for the light-independent reactions of photosynthesis are located.
1. Calvin cycle takes place in the stroma and light- dependent reactions take place in the granum, also light is not required for all the reactions of Calvin cycle.2. Calvin cycle assimilates CO2 to form organic compounds whereas in light reactions photolysis of water leads the formation of energy rich inorganic compounds.

Granum contains pigments, specifically chlorophyll molecules, which are responsible for capturing light energy for photosynthesis. The stroma does not contain pigments but does play a role in the Calvin cycle, where carbon dioxide is converted into sugars using the energy captured by the pigments in the grana.
On thylakoid membranes
GRANUM---- Granum is a membranous structure within the chloroplasts of plants and green algae that contains the chlorophyll and is the site of the light reactions of photosynthesis.
granum are stacks of thylakoids. grana are several stacks of thylakoids. :)
ATP and NADPH are produced by reactions in the thylakoids and are consumed by reactions in the stroma. The reason is because the reaction that takes place in the thylakoid is the light reaction and the one that takes place in the stroma is the light-independent reaction.

The light dependent reaction occurs in the chloroplast. In the light dependent reaction, chlorophyll pigments absorb solar energy. This energy is then converted into a chemical form (not glucose). The water molecule is split into oxygen and hydrogen molecules. The dark reaction or the carbon fixation period occurs in the fluid matrix or stroma of chloroplast. The hydrogen product from the first reaction is combined with the carbon dioxide molecules to makes sugars. This results in the C3 or C4 cycle.
The Calvin Cycle, also known as the light-independent reactions of photosynthesis, takes place in the stroma of the chloroplast. This cycle involves the conversion of carbon dioxide into glucose using energy from ATP and NADPH produced during the light-dependent reactions.
