Dear Soumya,

Thank you for asking!

In Cyclic photo-phosphorylation, the source of electron donation is chlorophyll pigment (P700). Energy from sun (photon) excites the electron in chlorophyll molecule to jump to an electron acceptor circulates within the PS I and the phosphorylation occurs due to cyclic flow of electrons. This whole activity is happening in stroma lamellae.

Hope the answer of the question!
