...."Molecular photovoltaics and the photoactivation of mammalian cells Kuritz, T.; Lee, I.; Owens, E.T.; Humayun, M.; Greenbaum, E. NanoBioscience, IEEE Transactions on Volume 4, Issue 2, June 2005 Page(s): 196 - 200 Digital Object Identifier 10.1109/TNB.2005.850480 Summary: Photosynthetic reaction centers are integral plant membrane protein complexes and molecular photovoltaic structures. We report here that addition of Photosystem I (PSI)-proteoliposomes to retinoblastoma cells imparts photosensitivity to these mammalian cells, as demonstrated by light-induced movement of calcium ions. Control experiments with liposomes lacking PSI demonstrated no photosensitivity. The data demonstrate that PSI, a nanoscale molecular photovoltaic structure extracted from plants, can impart a photoresponse to mammalian cells in vitro." ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/7728/30922/01435374. pdf?arnumber=1435374 same as lil sissy's link.

The polymer blend films resulting from the spin coating were phase separated and the photo response of the devices depended on the morphology of the segregation. We have studied different blend ratios by photoluminescence quenching, scanning force microscopy and photovoltaic measurements. External quantum efficiencies of 4.5% at 500nm were achieved for the less segregated polymer blend.
