Isosceles is a company that received a STTR Phase I grant for a project entitled: Full Spectrum Conjugated Polymers for Highly Efficient Organic Photovoltaics. Their their award is funded under the American Recovery and Reinvestment Act of 2009 and their project will demonstrate the feasibility of forming full spectrum highly efficient polymer solar cells from newly designed conjugated and potentially variable bandgap polymers that harvest visible through infrared light. The novel materials will be forged by incorporating Silole and donor-acceptor-donor moieties into the backbone and are expected to increase light harvesting and carrier mobility, and hence short circuit current output potentially by a factor of three over the state of the art. The key innovations of this work will also optimize energy levels to reduce voltage loss and further optimization of device structure and film morphology is expected improve fill factor. The primary objective of phase I is to determine the feasibility of forging full spectrum and high carrier mobility conjugated polymers that achieve highly efficient solar conversion. An ancillary goal of this work is arrive at an understanding of photophysical processes and device physics that will lead to optimal device fabrication during phase II. The environmental, societal and economic impacts of this technology are enormously broad. The ensuing abrupt drop in energy costs stemming from full spectrum harvesting promises to deliver stability and urgently needed relief to today's volatile oil based global economy. While photovoltaic (PV) production is already the fastest growing source of energy across the globe, the planned efforts of this STTR project are expected to disruptively reduce the projected cost of photovoltaic production in 2010 by a factor of 3. At a forecasted production cost of $0.70 per Watt, this research will demonstrate a technology that is competitive with the cost of electricity that is produced from fossil fuels. This technology will provide clean and cost competitive energy for home and industrial power, vehicle propulsion, consumer electronics, remote sensing, security, and an endless list of existing applications that currently rely on energy from fossil fuel.
Solarno is a company that received a STTR Phase I grant for a project entitled: Synthesis of multifunctional nanofibrous polyaniline/carbon composites. Their their award is funded under the American Recovery and Reinvestment Act of 2009 and their project will develop novel multifunctional materials based on polyaniline (PAni) nanofibers (PANFs) and carbon nanofibers(CNFs) for energy storage. Although PAni composites have been reported for a wide range of applications, including sensors, biosensors, photoelectrochromic cells, etc., due to their excellent electrical, thermal and mechanical properties, none capitalize on the enhanced properties expected from the combination of PANF with CNF. PANFs have greater electronic conductivity than PAni nanospheres and nanorods and can be synthesized on a variety of substrates. Solarno will use a proprietary process for synthesizing composites of PANFs on CNFs. In Phase I Solarno will use these composites as electrode materials for asymmetric supercapacitors, an enabling technology that provides both high energy and power, with the specific technical objectives of: synthesizing and characterizing PANFs on CNF substrates, and achieving supercapacitor performance of 15 Wh/kg, 10 kW/kg and >10 cycles, thus far exceeding current lead acid batteries in terms of power and cycle life. In Phase II we will improve the energy density of these devices to enable potential replacement of such batteries, and explore other functions for the composites, such as sensors and electro-chemical devices. The PANF/CNF composites developed by Solarno will be introduced to the supercapacitor market via materials sales, and partnering/licensing arrangements, and later to related electrochemical functions/applications. Solarno is targeting requirements of the Hybrid Electric Vehicle (HEV) market for its initial supercapacitor designs, and as such, the ultimate customers will be major automobile manufacturers. The market requires that capacitors provide higher energy density, reduced size, higher reliability, and lower cost. Commercially available EDLCs commonly provide energy densities around 4 Wh/kg, and power densities between 15-21 kW/kg. The supercapacitor developed here can excel in this market by providing energy density > 25 Wh/kg and better reliability (>2.0 x 104 cycles); the Phase I work will optimize the properties of our PANF/CNF composite to meet this goal. The supercapacitors will also be well-suited for load-leveling for renewable energy sources; direct societal benefits will come from improving the viability of HEVs and renewable sources, tied to reductions in fossil fuel consumption, providing bridge power for wind and solar power farms, and partially replacing lead acid storage batteries. The results of this work in optimizing PAni composites for supercapacitors will translate well into improved functionality for other applications.

Tisol is a company that received a SBIR Phase I grant for a project entitled: Scalable fabrication of mesoporous thin-films for production of efficient dye-sensitized solar cells. Their project aims to apply a specialized method to develop a rapid, large-scale and inexpensive thin film deposition technology. The goal is to enable the low-cost mass production and maintain the optimized nanostructures and film properties of efficient dye-sensitized solar cells. The broader societal/commercial impact of this project will be the potential to reduce production costs of materials used in dye-sensitized solar cells. Compared to other solar cell technologies, dye-sensitized solar cell technology has the potential of (1) low cost due to the abundance of elements that constitute the cell; (2) lightweight thus reduced installation cost and enhanced flexibility. However, recent advances in photovoltaics industry set a cost standard of < $1/Watt. If dye-sensitized solar cells were to be at par with current technologies on the market, the cost of thin film deposition has to be reduced. This project targets on the development of a high-throughput and large-scale thin film deposition process, which will make the solar electricity via dye-sensitized technology more cost-effective and thus more available.
Gratings Incorporated is a company that received a STTR Phase I grant for a project entitled: High Efficiency Thin-film Photovoltaics on Low-cost Substrates by Layer Transfer. Their their award is funded under the American Recovery and Reinvestment Act of 2009 and their project will apply high aspect ratio, nm-scale, columnar, and crystalline Si structures as templates for high-quality growth of thin-film GaAs solar cells on low-cost flexible substrates. Sub-10-nm Si seed layers are expected to facilitate growth of low-defect density GaAs films. The aspect ratio of nm-scale structures also serve as sacrificial layers for removal of completed GaAs solar cell. Epitaxial growth and characterization of GaAs films on nm-scale Si structures will be carried out at the Center for High Technology at the University of New Mexico. Successful phase I STTR research will lead to commercialization of high (~ 20 %) efficient, flexible solar cells for applications in a wide range of terrestrial and space environments. Multiple substrate re-use and inherent large area processing capability of Si will result in significant cost reductions. High quality heteroepitaxial GaAs growth on Si has been a subject of intense research. Due to its direct bandgap, GaAs is attractive for a number of optoelectronics applications and its integration with Si-based microelectronics has been a cherished goal. The lattice and thermal expansion mismatches with Si make it difficult to grow good device quality layers. We have recently demonstrated as the Si seed dimension is reduced below 100 nm dimensions, the quality of heteroepitaxial growth increases rapidly. The nm-scale Si structures are formed using low-cost, large area methods based on conventional integrated circuit processing methods. Successful research effort will lead to reduction in PV generation costs, and enhanced applicability of thin-film PV in terrestrial and space environments because in contrast with competing thin-film solar cells, GaAs thin-film solar cells will not suffer from light-induced performance degradation.
