EVSO: Cornell Researchers Create Much Cheaper Recipe for Making Solar Cells

Evolution Solar (PinkSheets:EVSO). The Dichtel group in the
Department of Chemistry and Chemical Biology at Cornell University
has developed a method to organize organic dyes into stacked sheets
that are porous for incorporation into flexible solar cells. The
process could revolutionize the way solar cells are made by
lowering costs dramatically, while creating highly-efficient and
easy-to-manufacture solar cells.
The process employs organic dye molecules assembled into a
structure known as a covalent organic framework (COF). The strategy
uses a simple acid catalyst and relatively stable molecules called
protected catechols to assemble key molecules into a neatly ordered
2D sheet. These sheets can be stacked on top of one another to form
a lattice that provides pathways for charge to move through the
material. At the core of the framework are molecules called
phthalocyanines, a class of common industrial dyes used in products
from blue jeans to ink pens. Phthalocyanines are also closely
related in structure to chlorophyll, which absorbs almost the
entire solar spectrum.
This structure is a model that can significantly broaden the
scope of materials that can be used in COFs. Once the framework is
assembled, the pores between the molecular latticework could
potentially be filled with another organic material to form light
and flexible solar cells.
"This framework developed by Cornell researchers could possibly
be one of the most significant advances in making solar energy more
competitive with fossil fuels,” stated Robert Hines, President of
Evolution Solar. “Also, advances like this could significantly
lower up-front costs for solar power systems, which has been a
deterrent for the industry that we would like to see
disappear.”
Evolution Solar is currently building a solar demonstration site
in partnership with Texas Southern University, to be located at the
University’s Houston Campus. The project should help Evolution
Solar acquire new projects in a sector that is growing to compete
in the energy industry, which includes BP (NYSE: BP), Apache
Corporation (NYSE: APA), Devon Energy Corporation (NYSE: DVN) and
EOG Resources Inc. (NYSE: EOG).
