In June, researchers created an early lab scale model of OctillionÂ’s transparent photovoltaic Â‘NanoPower WindowÂ’. Scientists successfully engineered and assembled a mechanically stable, see-through developmental prototype, which achieved optically active down-conversion and displayed good electrical properties with no electrical shorts.
Â“Recently, weÂ’ve been fortunate to accomplish significant breakthroughs, and as a result, IÂ’m proud to announce that Octillion has now formally committed to doubling our research funding pursuant to our Sponsored Research Agreement, which allows our collaborating scientists to more aggressively exploit these important findings,Â” explained Octillion President and CEO, Mr. Harmel S. Rayat.
Key to the development of OctillionÂ’s transparent NanoPower Windows is a proprietary spray coating of a silicon nanoparticle film, which is fluorescent and able to convert the sunÂ’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 process for spraying the silicon nanoparticles onto glass surfaces is unique to Octillion, and is among the CompanyÂ’s major research achievements. Earlier this year, researchers developed a protocol for reliably depositing nanoparticles onto glass surfaces using a proprietary electro spray system able to produce nanofilms of controllable thickness. Importantly, the silicon nanoparticles retained their high efficiency of down conversion of UV light to the visible after being sprayed, a procedure that does not compromise the optical characteristics of the nanoparticles, both in intensity and spectral distribution, a prerequisite for efficient photovoltaic conversion.
In an important breakthrough just last month, researchers developed an early model of the worldÂ’s first transparent photovoltaic windows of its kind, successfully Â‘stackingÂ’ silicon nanoparticles between ultra-thin films of metal, onto a glass surface. Preliminary tests have shown that this stack is mechanically stable and of even thickness. Tests for optical characterization have demonstrated that the model is of a high-quality see-through architecture, important to maintaining maximum transparency of a finished commercial product.
Â“The research advances weÂ’ve achieved over the past few months are encouraging enough to prompt us to significantly increase our commitment to aggressively fund the development of our NanoPower Window technology. With this additional injection of capital to fund personnel, equipment and materials, IÂ’m looking forward to seeing our leading edge technology build on its momentum and move forward in the weeks and months ahead,Â” concluded Mr. Rayat.
