Perovskite solar cells with laminated carbon electrodes reach 20.4% efficiency
Scientists in Germany report a method to boost performance of perovskite solar cells made with laminated carbon electrodes that are compatible with typical hole transport layers.
Thieves steal 50 km of cable from 11 MW solar farm in Germany
Thieves stole 50 km of cable worth about €100,000 ($117,400) from an 11 MW solar project in southern Germany, with repair costs expected to exceed the material loss, according to police.
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.
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.
Renewables overbuilding, proactive curtailment can reduce Europe’s energy system costs
New research from the Netherlands showed that renewables and short-term storage can meet around 92.5% of Europe’s electricity demand in future energy scenarios, with the remaining 7.5% being satisfied by green hydrogen. The scientists considered Europe as fully self-sufficient with zero import-export of power or hydrogen, with each of the 37 countries included in the modeling having a self-sufficiency rate of at least 80%.
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.
Cobalt-iron catalyst boosts zinc-air battery stability and performance
Engineers at Monash University in Australia have developed a new catalyst they say could bring zinc-air batteries “closer to real-world, grid-scale and transport uses.”
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.
