But there is hope in Congress's recent approval of funding for PARC and 45 similar Energy Frontier Research Centers (EFRCs) through the Department of Energy.
"The precedent in this case is the number of centers funded," Bocian said. "Normally the National Science Foundation calls for proposals and eventually funds three or four centers."
The $277 million allocated for the 46 EFRCs is significant, especially in that it requires no "deliverables" (functioning products) but rather seeks to address basic science questions.
Shiny silicon-wafer cells are extremely brittle, but Bocian explained that the new solar cells would be flexible, and could be integrated with textiles, allowing clothes to act as a walking power source for cell phones and computers.
He hopes to aid the development of what he calls "bio-inspired" antenna systems, which will collect and focus light to power solar cells.
These systems are bio-inspired because they are based on the dynamics of natural proteins. Nature "engineers" rings of light-harvesting complexes, each hosting a certain number of chlorophylls (photosynthetic light-absorbing pigments). Organisms simultaneously absorb light from different wavelength regions, significantly increasing their energy efficiency.
Bocian and his lab (funds will support at least one student and a post-doc each year for the next five years) use resonance Raman spectroscopy and other techniques to study chromophores, light-absorbing molecules. Resonance Raman spectroscopy, Bocian explained, allows his lab to study the vibrational resonance of individual molecules of interest.
Bocian noted that one advantage of the new cells is that they are more amenable to applications where today's solar cells cannot be used.
"Moreover, the main problem with today's solar cells is that they are not cost effective," he said, "and that's what we're hoping to change with this project."
