In NCERT it is clearly mentioned that no NADPH is synthesised in the photorespiration. But here its showing the formation of NADH (are not NADHP and NADP same)

Dear student.

NADPH and NADH are not same. NADPH is the reduced form of NADP. Its full form is nicotinamide adenine dinucleotide phosphate. NADP can be derived from any carbon source.  NADP reductase is a type of oxido-reductase enzyme that help in making reducing power NADPH  by transferring electrons from ferrodoxin to  NADP⁺.
It is situated on the outer side (stroma side) of thylakoid membrane. It obtains electrons from PSI and protons from matrix to reduce NADP⁺ to NADPH.
 

NADPH stands for Nicotinamide adenine dinucleotide phosphate is a coenzyme used in anabolic reactions, such as lipid and nucleic acid synthesis, which require NADPH as a  reducing agent.

NADPH is necessary for stage two of photosynthesis, the Calvin Cycle, to occur. During that cycle, NADPH reduces carbohydrate molecules into carbon-carbon bonds until they form two 3-carbon sugar-phosphate molecules. NADPH is a reduced form of nicotinamide adenine dinucleotide phosphate. It is a final product of the light reactions of photosynthesis.
