About Ampulse

Ampulse is a developer of film-silicon photovoltaic (PV) solar cell technology. Spun out of the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) with $1 million+ in pre-seed funding from Battelle Ventures and its affiliate, Innovation Valley Partners, the company aims to utilize proven and patented manufacturing techniques and materials developed in partnership between the DOE's National Renewable Energy Laboratory (NREL) and ORNL. Targeting the high-conversion efficiencies achievable in crystalline silicon PV (c-Si) and the manufacturing cost advantages of emerging thin-film PV (TF-PV), film-silicon PV integrates of both approaches into a true next-generation PV cell technology. Recipient of the Best Early Seed Investment of the Year Award at NREL's 2008 Clean Energy Industry Growth Forum, Ampulse is based in Denver, Colo. Kef Kasdin sits on the Board.

Accustrata is a company that received a SBIR Phase IB grant for a project entitled: Real time optical control system for thin film solar cell manufacturing. Their research project relates to a real-time optical control system in the manufacture of next generation thin film solar cells and panels. The proposed system improves thin film solar cell manufacturing by improving the quality of the individual solar cells and panels. It allows manufacturing of more consistent and uniform products resulting in higher solar conversion efficiency and manufacturing yield. The proposed system uses patented miniature fiber optic sensors, installed at many locations in the film deposition chambers. They monitor different spots on the substrate and obtain real time measurements of film properties. The system compares the measured with the targeted values and provides immediate correction, improving film uniformity and narrowing material property distribution. It returns most of the products to their targeted specification, which would otherwise be rejected. This proposal will reduce waste and improve the manufacturing yield and the conversion efficiency of thin film solar cells and panels. It has specific benefits for the large-size solar panels, which are manufactured at higher cost today due to insufficient manufacturing yield. The proposed technology will reduce the time it takes for solar panels to reach grid parity with traditional energy sources. The proposed technology will also facilitate the development of numerous other applications for next generation thin film based products such as photonic crystals, nanotechnology, meta-materials, multi-junction solar cells, printing and counterfeiting control. This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

Gratings Incorporated

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.

PrimeStar Solar

Primestar Solar is a company that received a SBIR Phase I grant for a project entitled: High Quality, Low Cost, Polycrystalline CdS/CdTe Photovoltaic Cells. Their will develop new processes for producing lower cost and higher quality thin films from the compound semiconductors CdS and CdTe. These will be used to more inexpensively produce high performance photovoltaic modules that generate electricity from sunlight. Thin film CdTe-based photovoltaics currently require a post-deposition CdCl2 treatment and anneal to achieve reasonable performance. This anneal is known to increase the grain size in some films and increase the minority carrier lifetime in all CdTe films. The minority carrier lifetime is generally correlated with device efficiency in photovoltaic cells. However, the CdCl2 anneal cannot be optimized to maximize the minority carrier lifetime because attempts to do so have caused film delamination. Film delamination occurs due to strain induced during the anneal at the interface between the film and the glass substrate. This proposal seeks to develop a film deposition process that simultaneously avoids this problem and makes better quality films. This process will foster large grain growth, defect passivation, and grain boundary passivation while eliminating the need for a post-deposition CdCl2 treatment and anneal. This will result in higher efficiency solar cells and a streamlined production process. Commercially, solar photovoltaic modules are a silent, pollution free means to generate electricity from sunlight. Once the capital investment is made to install a photovoltaic electricity system, its operating cost is essentially zero because its "fuel", sunlight, is free. Photovoltaic electricity provides a means for homes to generate as much energy as they use over the course of a year. The production of photovoltaic modules has been increasing 20-30% annually for the past decade due to increases in efficiency and reductions in cost. However, for photovoltaics to achieve significant market penetration into mainstream electricity generation, this growth rate must be continued. This requires further increases in module efficiency and reductions in module cost. This research proposal addresses both of these issues. Successful development of this technology will ensure the marketplace success of CdTe photovoltaic modules, and pave the way for widespread stable-priced, sustainable, pollution-free electricity generation.
