Hi, does anyone have an opinion about this recent review article, and
also would it even be possible to have quantum correlations in man-
made solar cells? Thanks.

We review recent theoretical and experimental advances in the
elucidation of the dynamics of light harvesting in photosynthesis,
focusing on recent theoretical developments in structure-based
modeling of electronic excitations in photosynthetic complexes and
critically examining theoretical models for excitation energy
transfer. We then briefly describe two-dimensional electronic
spectroscopy and its application to the study of photosynthetic
complexes, in particular the Fenna-Matthews-Olson complex from green
sulfur bacteria. This review emphasizes recent experimental
observations of long-lasting quantum coherence in photosynthetic
systems and the implications of quantum coherence in natural
photosynthesis.

Paper [1] shows a similar magnitude of quantum coherence in conducting
polymers.

The work mentioned in [2] shows that an individual photon can excite
up to three electrons at once within quantum dots, and there is also
both previous and ongoing research on combining quantum dots with
polymers, e.g., just google the phrase "quantum dots polymers".

There's an opinion at CERN.

photosynthetic energy transfer process"
