JinkoSolar claims 33.24% efficiency for perovskite-silicon tandem solar cells
JinkoSolar says it has achieved a 33.24% efficiency rating for its perovskite-silicon tandem solar cells, confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences.
Long-duration energy storage poised to outcompete lithium-ion batteries
While most long-duration energy storage (LDES) technologies are still early stage and costly compared to lithium-ion batteries, some have already, or are, set to achieve lower costs for longer durations, finds BloombergNEF.
Study finds excessive row spacing has limited effect on improving PV system performance
Scientists in China have tested the influence of panel row spacing in increasing a PV system performance in a full-scale outdoor PV array experimental platform. They found that larger row spacing plays a limited role in improving thermal convection, observing that solar irradiance and wind speed are the key parameters for optimal PV system design.
Longi introduces 630 W HPBC modules with 23.3% efficiency
Chinese manufacturer Longi says its new Hi-MO X6 Scientist series has a temperature coefficient of -0.28%/C and a power output ranging from 620 W to 630 W. They rely on the company’s proprietary hybrid passivated back contact cell technology.
REC launches 640 W heterojunction solar module with 22.5% efficiency
REC has developed a new series of heterojunction solar panels with efficiencies up to 22.5% and an operating temperature coefficient of -0.24% per degree Celsius.
Austrian startup offers double-axis tracking system for agrivoltaics
Anywhere Solar says its new trackers have a module area of 75 m2 and can host PV systems up to 19 kW in size. When deployed horizontally, the systems allow vehicles up to 4.3 meters high to pass underneath.
Renewable manufacturing costs up to 200% lower in China, says WoodMac
Wood Mackenzie says in its latest report that low prices and integrated supply chains allow Chinese manufacturers to supply more than 65% of total global demand for renewables equipment, with its exports growing by 35% between 2019 and 2023.
Renewables must triple by 2030 to hit net-zero by 2050, says BloombergNEF
BloombergNEF says in a new report that solar and wind must drive most emissions cuts before 2030 to stay on track for net zero by 2050. Its net zero scenario targets a combined solar and wind capacity of 31 TW by 2050.
Weekend read: Déjà vu on the polysilicon market
Haven’t we been here before? The polysilicon industry is shifting from shortage to oversupply but a few things are different from market cycles of the past, as Bernreuter Research founder Johannes Bernreuter explains.
Research shows repaired PV modules can perform with acceptable losses
A research group in Spain has demonstrated the technical feasibility of using repaired solar modules with satisfying results. However it warned that there is an urgent need to define a protocol for evaluating the features of a “viable” repaired panel.
