the possibility for costly delays in implementing our capacity ramp. We have also identified valuable methods of improving performance, yield, throughput, and materials utilization.”
ISET’s pilot line produces monolithically integrated CIGS modules on glass substrates with an area of 1ft2. Recent production runs have achieved 11% cell average conversion efficiency.
Additionally, ISET’s R&D team has fabricated laboratory devices with better than 14% efficiency.
Dr. Kapur noted that research efforts were “on track to reach 16% in the near term.” ISET has established its pilot production line in a facility that can accommodate an expansion to an annual capacity of 30 MW while generating over 100 additional jobs and providing competitively priced PV products to local and international markets.
International Solar Electric Technology (ISET) is a privately held corporation located in Chatsworth, California (USA). The company was founded in 1985, and manufactures Copper Indium Gallium di-Selenide (CIGS) thin-film solar cells using a patented ink-printing process.
US DOE Selects PPS to Develop SiC Converter for Hydropower Applications
The firm will develop the system in order to reduce the cost of ocean and hydropower sources, while making them more efficient and more compatible with the existing electric grid.
Princeton Power Systems (PPS) was awarded a Phase II Small Business Innovative Research (SBIR) contract from the US Department of Energy (DOE), Office of Science to develop an advanced power conversion system for commercial tidal, wave, and related hydropower applications.
Using a high-power (1.5MW) converter design and silicon carbide (SiC) semiconductor switches, enabled by PPS’ patented AC-link(TM) circuit topology, will allow for a much higher power-density.
Additionally, it will provide a direct connection to 12 kV or higher power lines without using a transformer. This will drastically reduce the space
and logistic requirements for the power electronics in tidal, wave, and other hydropower systems.
Furthermore, the converter will increase the efficiency of transmitting power onshore and interconnecting with the utility grid. Ultimately, this system will reduce the cost of ocean and hydropower sources, while making them more efficient and more compatible with the existing electric grid.
Darren Hammell, Executive VP of Business Development, stated, “We are excited to expand the use of our technologies to the rapidly growing sector of grid-connected hydropower applications. Our history of providing rugged components for Navy applications will ensure that our designs can endure the unique environmental requirements of these systems.”
Wave, tidal, and other hydropower generation systems are clean, non-polluting energy generation sources that have the potential to displace large amounts of polluting, non-renewable power plants.
Princeton Power Systems, founded in 2001, is a manufacturer of advanced power conversion products and alternative energy systems, with patented electronics that provide a more reliable and cost-effective means for converting electric power cleanly and efficiently. The company has solutions for renewable energy, distributed power generation, and military applications.
SiC Systems & Smart Lighting ERC Funded to Develop LEDs on 6” SiC
With the $200,000 award, it is hoped the partnership can explore new approaches to driving GaN to higher levels of efficiency. The aim is to broaden the range of operating wavelengths from those obtainable on current LEDs grown on sapphire.
The National Science Foundation (NSF) has awarded a $200,000 grant to SiC Systems to partner with the Smart Lighting ERC in order to develop LEDs with increased efficiency.
