September 24, 2024 Emiliano Bellini The NBJE610 moduleImage: sharpSharp has unveiled new n-type monocrystalline bifacial solar panels based on tunnel oxide passivated contact (TOPCon) cell technology.The NBJE610 The double-glass module has 132 half-cut solar cells based on G2 wafers and a design with 16 busbars. It features an energy conversion efficiency of 22.58% and an output power of 610W.The new panels measure 2,382 mm x 1,134 mm x 30 mm and weigh 34 kg. They…
The U.S. solar industry has a complicated relationship with China. The silicon solar cell may have been invented in America seventy years ago, but manufacturing dominance has since shifted to China and Southeast Asia. The manufacturing tax credits included in the Inflation Reduction Act of 2022 have achieved the goal of reviving domestic solar energy production across the country, but most new U.S. factories opening their doors have Chinese tyres. More solar panels are being made in America than ever, but it is unclear whether they are really American and whether anyone can do anything about it. Chinese companies are…
As the world turns to solar energy as a clean, renewable power source, understanding the factors that influence solar panel performance becomes important. One of the most significant yet often misunderstood factors is temperature. In this guide, we’ll explore the relationship between solar panel efficiency and temperature, diving into the science, practical implications, and strategies for optimizing performance. Solar Panel Efficiency Solar panel efficiency refers to the amount of sunlight that a panel can convert into usable electricity. For example, if a solar panel has an efficiency rating of 20%, it means that 20% of the sunlight hitting the panel…
Energy storage company Discover Energy Systems has been given a new name Bloom power and will continue to offer lithium-based energy storage solutions to North American customers. Bloom’s history now spans more than 75 years in the energy storage industry. Partners and customers will continue to experience the same level of commitment and service that characterizes Discover Energy Systems. “As we expand our offerings and reach new markets, a more inclusive brand that fully reflects our capabilities and direction is essential,” said Brendon Sauer, CEO of Bloom Power. “We are excited about this new chapter and look forward to building…
An international research project investigated the feasibility of converting solar energy into chemical energy with the design of a hybrid device with a solar energy storage and cooling layer integrated with a silicon-based solar cell. During testing, the device recorded record energy storage efficiency and reduced the cell surface temperature by approximately 8 C under standard solar irradiation conditions. September 24, 2024 Patrick JowettAn international research team led by the Universitat Politècnica de Catalunya in Barcelona created a hybrid device that combines molecular solar thermal energy (MOST) with silicon-based photovoltaics. The researchers say this is the first hybrid device that…
The all-vanadium liquid flow industrial park project is taking shape in Baotou city in China’s Inner Mongolia Autonomous Region, backed by a CNY11.5 billion ($1.63 billion) investment. Meanwhile, China’s largest vanadium flow electrolyte base is planned in Panzhihua city, Sichuan province. September 24, 2024 Marija Maisch By ESS newsChinese vanadium redox flow battery specialist Hunan Yinfeng New Energy plans to invest CNY11.5 billion ($1.63 billion) in developing a major production facility in Inner Mongolia.The project is expected to play an important role in promoting the adoption of vanadium redox flow batteries, one of the most promising large-scale energy storage technologies…
An Italian research group has fabricated a 110 cm² perovskite solar panel with an inverted configuration and a hole transport layer that uses nickel oxide instead of the commonly used poly(triarylamine) (PTAA). The proposed architecture aims to achieve high efficiency that is competitive with PTAA-based panels while improving stability. September 24, 2024 Emiliano BelliniResearchers from the University of Rome Tor Vergata in Italy have developed 15 cm x 15 cm inverted perovskite solar modules based on a hole transport layer (HTL) made of inorganic nickel oxide (NiOx).“Our research stands out for optimizing the deposition of nickel oxide over a large…
A new initiative now offers companies in Malaysia the opportunity to purchase green energy directly from renewable energy developers via the national grid. The Ministry of Energy Transition and Water Transformation (PETRA) estimates it will generate more than MYR10 billion ($2.4 billion) in direct investment. September 23, 2024 Patrick Jowett Image: Bari Abikar/UnsplashMalaysia’s PETRA has issued the regulatory framework for its Corporate Renewable Energy Supply Scheme (CRESS).The program allows companies to purchase green energy directly from renewable energy developers through Malaysia’s national grid. It officially opened on September 20, but was first announced in July.PETRA has recently been published guidelines…
Lyten’s lithium-sulfur batteries are being tested on the ISS Lyten, a leader in supermaterial applications and lithium-sulfur battery technology, announced that its rechargeable lithium-sulfur battery cells have been selected for testing aboard the International Space Station (ISS). The Department of Defense’s Defense Innovation Unit (DIU) is funding this project as part of its ongoing collaboration with Lyten focused on the development and production of lithium-sulfur batteries. As part of this agreement, DIU will fund Spacebilt/Skycorp’s integration and testing of Lyten’s rechargeable lithium-sulfur cells. The batteries will undergo rigorous testing under launch, orbital and recovery conditions, aimed at assessing their viability…
The Chinese module maker and the Australian National University used phosphorus diffusion capture agent and another defect mitigation strategy to improve the quality of n-type wafers. The proposed process helped improve the material quality, especially at the tail ends. September 23, 2024 Valerie ThompsonResearchers from the Australian National University and Chinese PV module manufacturer Longi examined the wafer quality of n-type industrial blocks made via the Recharged Czochralski (RCz) process, applying two defect mitigation strategies: Tabula Rasa (TR) and phosphorus diffusion scavenger (PDG). to further improve the lifespan of the bulk.TR is commonly used to resolve oxygen clusters or precipitates…
