Five early-stage companies are announced as winners of the SunRISE TechBridge Challenge, which was designed to identify innovations in solar materials and technologies to reduce the levelized cost of energy for photovoltaic systems.
Researchers at the University of New South Wales (UNSW) have achieved a world record conversion efficiency of 7.6% for a 1cm2 copper zinc tin sulfide (CZTS) solar cell. Japan’s Solar Frontier, with IBM and Tokyo Ohka Kogyo, have previously achieved 12.6%, however on a smaller 0.42cm2 substrate.
More than 50 renewable energy startups will be showcasing their solutions at Ecosummit in Berlin on April 26 and 27. Is there still room for early stage companies to make an impact in the solar industry? pv magazine discusses new trends and opportunities in cleantech fundraising with Ecosummit founder and CEO Jan Michael Hess.
The seventh edition of the International Roadmap for Photovoltaics (ITRPV) has confirmed that PV producers are continuing to track the historic solar learning curve of 21%. A range of wafer, cell and module production technologies will see multicrystalline PV modules being produced by 2026 with an efficiency of 310 W, in a 60-cell configuration.
Renewable energy advisory DNG GL has called for more sophisticated reliability testing for new and novel materials being deployed in the renewable energy sector. Alternative semiconductor technology, such as perovskites, and innovative battery chemistries will be required if the Paris climate goals are to be met, the international advisory group argues.
As solar manufacturers return to profit an appetite for new technologies is growing. This was one of the key messages at this years Future PV Forum where PERC production at volume, new processes for III-V semiconductors and the rapid progress of perovskites were discussed by technologists, researchers and investors.
UCLA researchers have developed a metal oxide sandwich perovskite cell that enhances the stability of the promising semiconductor by more than 10 times. The approach uses two metal oxide layers on either side of the perovskite material, protecting it rapid degradation when exposed to air.
