The impact of sunlight spectral shifts on bifacial perovskite-silicon tandem solar cells
Experts from the International Solar Energy Society explains how regional spectral shifts of the standard spectral distribution of sunlight bring new insights into the performance of bifacial perovskite-silicon tandem solar cells.
Inox Solar starts production at first 1.2 GW phase of module plant in India
Inox Solar has commissioned the initial 1.2 GW phase of its 3 GW solar module factory in India, advancing its plan for full-scale domestic production.
New open-access simulation software for solar cell modeling
Developed by a professor at the Polytechnic University of Catalonia, the Soley software is claimed to enable precise optoelectronic modeling of photovoltaic devices and accurately reproduce the behavior of photodiodes under illumination.
World’s largest vertical rooftop solar installation deployed in Norway
Vertical solar specialist Over Easy Solar has broke its own record for the world’s largest rooftop vertical solar array with a 320 kW system in the north Norwegian city of Tromsø.
Copper-metalized heterojunction solar cells close to achieve same efficiency as silver-based counterparts
Researchers in Germany have shown that heterojunction solar cells screen printed with silver-copper on the front side and silver paste on the rear side can achieve a 0.13% efficiency gain over reference screen-printed bifacial cells based on silver alone. The research group worked specifically on dispensing and screen printing as printing methods.
Swiss startup offers timber-framed solar carport
Urbanpv has developed a timber-framed 46 kW parking lot design for ten parking spaces including the access lane.
Enhancing dual-axis solar tracker performance with new optimization techniques
Researchers in India have developed two solar tracker optimization techniques can purportedly increase power generation by up to 54.36% when combined. One uses a light sensor and the other relies on data from GPS and a real-time clock.
Spanish startup offers portable solar-plus-storage generators for irrigation
Spanish startup Nomad Solar Energy and Full&fast have deployed a portable solar-plus-storage system at a Madrid farm to provide off-grid power for irrigation.
Gautam Solar unveils 630 W TOPCon module for utility-scale solar projects
Gautam Solar has introduced 630 W R-Series tunnel oxide passivated contact (TOPCon) modules for utility-scale PV projects, approved under India’s Approved List of Models and Manufacturers (ALMM) and Bureau of Indian Standards (BIS).
Korean scientists achieve 21% efficiency in polycrystalline solar cell for underwater environments
The cell was fabricated with a 2.3 nm-thin layer of gallium oxide, a silver busbar aimed at improving charge collection and silicon nitride anti-reflection coating. It was encapsulated within a watertight 3D-printed box to ensure impermeability.
