‘Energy transition requires us to do things better’
The annual EU PVSEC conference got under way virtually this morning via an online platform since the planned event in Lisbon could not go ahead due to the Covid-19 pandemic. Opening presentations revealed an air of optimism in the PV industry, amid expectations of a rapidly rising share in the energy mix, growing conversion efficiencies, advancing technology pathways and innovative solutions to the problem of integrating high levels of PV into electricity grids.
New manufacturing technique for antimony sulfide-selenide PV cells
Chinese researchers have discovered a new hydrothermal method for the direct deposition of antimony sulfide-selenide films. They used ethylenediaminetetraacetic acid to regulate the reaction system, giving the film a flat, compact surface morphology. It has an efficiency of 10.5%, an open-circuit voltage of 664 mV, a short-circuit current of 23.8 mA cm−2, and a fill factor of 66.3%.
Perovskites in space
Scientists led by the Technical University of Munich have packed a variety of perovskite and organic solar cells onto a rocket, and sent it into orbit 240 kilometers above the planet’s surface. Their results demonstrate strong potential for such technologies to power satellites and even deep space missions.
Floating PV powering sieving machines, suction excavators at German quarry
Rheinland Solar has built a 750 kW floating solar plant to power several sieving machines and suction excavators at a quarry in Germany. On weekends, the excess electricity is sold to the grid at market prices.
Zebra IBC cell with 24% efficiency moves to large-scale production
Netherlands based manufacturer Energyra this week introduced a new back contact module, which it has developed in partnership with Dutch research institute TNO and Germany’s ISC Konstanz. A prototype module was unveiled yesterday in a small presentation at Energyra’s factory in Zaandam, Netherlands. The company is targeting large-scale manufacturing by the end of 2020.
Hanwha Q Cells to offer its most powerful panels in Europe
The South Korean PV manufacturers is bringing its three most powerful solar panels to Europe. All of them are based on its Q.antum Duo Z tech, which reduces the gaps between cells and drives up module efficiency by 4% in relative terms.
Light and shade of 500 W plus solar panels – part IV
In the fourth and final article of a series, pv magazine editor Pilar Sánchez Molina analyzes with industry experts challenges and opportunities created by new panels with power output exceeding 500 W.
Machine-learning for PV module cleaning
French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.
Giant agrivoltaic project in China
The Baofeng Group is building a 1 GW solar park which is hosting a goji berry plantation in the Binhe New District on the eastern banks of the Yellow River in the Ningxia Province. Around 640 MW have so far been grid-connected. Huawei is providing the inverters for the project.
Inverted pyramid-based PERC solar cell with 21.4% efficiency
A Chinese research group has developed a PERC cell on a commercial 180-μm-thick monocrystalline silicon wafer with a standard size of 156 × 156 mm2. The cell has an open-circuit voltage (VOC) of 0.677 V, a short short-circuit current (ISC) of 9.63 A, and a fill factor of 80.30%.
