All solar cell efficiencies at a glance – updated
The research group led by Professor Martin Green has published Version 65 of the solar cell efficiency tables. There are 17 new results reported in the new version.
Lithuania bans remote Chinese access to solar, wind, storage devices
Lithuania has decided to tighten its cybersecurity laws, banning manufacturers from countries deemed national security threats, including China, from remotely accessing management systems of solar, wind, and storage facilities. The European Solar Manufacturing Council has backed the move.
Testing to start on 100 MWh sand-based thermal battery in Finland
Finnish startup Polar Night Energy is building an industrial-scale thermal energy storage system in southern Finland. The 100-hour, sand-based storage system will use crushed soapstone, a by-product from a fireplace manufacturer, as its storage medium.
Schneider Electric introduces portable solar power station
The OffGrid portable power station provides power for outdoor adventures as well as in hurricane-ravaged areas.
Epsilon, Korea’s Daejoo join hands to develop graphite-rich silicon composite anode material for EV lithium batteries
Epsilon Advanced Materials and Daejoo Electronic Materials aim to jointly develop graphite-rich silicon composite anode materials for lithium-ion batteries with a capacity of 450 – 600 mAh/g, thereby increasing discharge capacity by 50% and life span by thousands of cycles.
Shoots of growth for Indian green hydrogen
India is laying the foundations of a hydrogen economy with huge governmental support. pv magazine spoke to Jakson Green CEO Bikesh Ogra about the company’s manufacturing and production activities in light of India’s ambitious hydrogen plans and the central role electrolyzer manufacturing is set to play.
Solving the UV problem of n-type solar
Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.
Optimal tilt angle for bifacial PV deployed on white-painted ground surfaces
Scientists in India have analyzed the performance of a bifacial PV module installed on a white-painted ground surface and have found a 30-degree tilt angle outperforms all other inclinations angles in terms of power output.
A look at next generation battery cells
The battery industry is experiencing a seismic shift with advancements in prismatic cell technology, led by companies like Cornex, which promise to reshape energy storage solutions.
Will Indian solar manufacturers go back-contact to the future?
Indian PV manufacturers are looking beyond tunnel oxide passivated contact (TOPCon) solar. Back-contact (BC) devices are an enticing prospect but many feel the technology is not mature enough. Uma Gupta considers the cost, yield, and reliability challenges that BC solar has to overcome.
