Solar Greenhouses Generate Electricity and Grow Healthy Crops (link)

Excerpt:
“We have demonstrated that ‘smart greenhouses’ can capture solar energy for electricity without reducing plant growth, which is pretty exciting,” said Michael Loik, professor of environmental studies at the University of California, Santa Cruz, and lead author on a paper that appears in the current issue of the American Geophysical Union’s journal Earth’s Future.

Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel technology that generates electricity more efficiently and at less cost than traditional photovoltaic systems. These greenhouses are outfitted with transparent roof panels embedded with a bright magenta luminescent dye that absorbs light and transfers energy to narrow photovoltaic strips, where electricity is produced. WSPVs absorb some of the blue and green wavelengths of light but let the rest through, allowing the plants to grow.

Here is the paper:

Sounds like the longevity of the greenhouse panels is not known yet.  "An accounting of the full costs of WSPVs in comparison to Si-PV awaits a comprehensive life cycle analysis."
