June 8, 2007– Octillion Corp. of Vancouver, B.C. says that in early models of its photovoltaic NanoPower Windows product, scientists have successfully engineered and assembled a mechanically stable, visually transparent prototype that achieves optically active down-conversion and displays good electrical properties with no electrical shorts. This marks a significant breakthrough in development of a working prototype capable of generating electricity from sunlight without losing significant transparency, explained Mr. Harmel S. Rayat, President and CEO of Octillion Corp.

In developing an early model of the world’s first transparent photovoltaic windows of its kind, Octillion researchers have successfully ‘stacked’ silicon nanoparticles between ultra-thin films of metal, onto a glass substrate. Preliminary tests have shown that this stack is mechanically stable and of even thickness. Tests for optical characterization have demonstrated that the model is a high-quality see-through architecture, important to maintaining maximum transparency of the finished commercial product.

Key to development is a proprietary, fluorescent spray coating of a silicon nanoparticle film that converts the sun’s energy into electricity. The process of producing these silicon nanoparticles is supported by 10 issued US patents, 7 pending US patents, 2 issued foreign counterpart patents and 19 pending foreign counterpart patents. The proprietary process for spraying the particles onto glass surfaces is unique to Octillion, and is among the company’s major research achievements.

In tests of the developmental prototype window, Octillion’s silicon nanoparticle film was able to successfully convert high energy photons into lower energy photons, thus optimizing electrical conversion by preventing high energy photons from being unnecessarily wasted through conversion into heat.

Octillion, together with its wholly owned subsidiaries, is a technology incubator focused on the identification, acquisition, development and eventual commercialization of emerging technologies.
