September 17, 2024 Emiliano Bellini The NBJG445R moduleImage: sharpSharp has unveiled new n-type monocrystalline bifacial solar panels based on tunnel oxide passivated contact (TOPCon) cell technology.The modules are equipped with 96 half-cut solar cells based on G12 wafers and a design with 16 busbars. They also feature an energy conversion efficiency of up to 22.52% and an output power of 430 to 450 W.“The bifacial NBJG445R and NBJG450R modules have a white coating on the…

An international research team has investigated how thermoelectric subcooling can be integrated into propane heat pumps to reduce energy consumption in the vapor compression system. Their work showed that this combination can not only reduce electricity consumption, but also significantly improve heat pump performance. September 17, 2024 Emiliano BelliniAn international research team has conducted a computational analysis on propane (R290) vapor compression heat pumps that integrate a thermoelectric subcooler (TESC) to reduce the energy consumption of vapor compression systems and found that this combination can increase the coefficient of performance of the heat pumps by 12.29% .In the newspaper “Effect…

Harnessing the Sun’s Power for Year-Round Cultivation In the ever-evolving world of agriculture and horticulture, the integration of renewable energy sources has become increasingly important. Among these innovations, the use of solar panels for greenhouse heating stands out as a game-changing solution. This approach not only addresses the energy-intensive nature of greenhouse operations but also aligns with the growing demand for sustainable farming practices. In this guide, we’ll explore using solar panels to heat greenhouses, examining the benefits, challenges, and best practices for implementation. Solar Energy and Greenhouse Heating Before diving into the specifics of solar-powered greenhouse heating, it’s crucial…

From pv magazine 24/09The residential solar industry is often called the “solar roller coaster” in the United States because it has seen peaks and valleys in customer demand, business profitability and investment.SunPower, one of the largest and oldest solar energy companies in the United States, has suffered its latest dip after announcing bankruptcy and delisting from the Nasdaq Stock Exchange. Once valued as worth billions of dollars, SunPower shares fell more than 99% from their all-time high valuation in 2007.The company provided homeowners with rooftop solar, energy storage and electric vehicle (EV) charging. It operated a dealer network in which…

Empact Technologies, a provider of IRA compliance management software and services, and Crux, the sustainable finance company, jointly announced a new partnership. The partnership allows Crux to connect project developers and tax credit buyers directly to Empact for tax credit compliance, and Empact to connect project developers to the Crux platform to monetize project tax credits. The IRA will provide an estimated $1.2 trillion in stimulus by 2032. The portability of federal clean energy tax credits has created a new market mechanism to finance clean energy projects, opening doors for both traditional players and buyers of non-traditional tax credits to…

The new solar cell uses tungsten sulfide as a field layer on the back surface. According to the makers, this layer can be incorporated into conventional CIGS solar cells to improve their efficiency and reduce the cost of the absorber material. September 17, 2024 Emiliano BelliniResearchers from Visvesvaraya National Institute of Technology in India have proposed a new copper-indium gallium diselenide (CIGS) solar cell structure using tungsten disulfide (WS2) as the back surface field (BSF) layer.BSF layers consist of a higher doped area at the back of the solar cell and are often used to increase the voltage of a…

The practical issue of taking apart a dead PV system and moving the components to their next destination has received less attention than recycling and second life applications. In the United States, Decom Solar offers dismantling for commercial and industrial (C&I) solar projects. pv magazine spoke to Decom Solar co-founder Stephen Burns for an update. September 17, 2024 Mark Hutchinspv magazine: Can you tell me something about Decom Solar and its work?Stephen Burns: Before I started Decom Solar, I worked in the solar energy sector for a project developer for 10 years. At that time, we started seeing clients requesting…

Norway’s REC Silicon says it has completed construction of the restarted Moses Lake plant and will ship its first commercial polysilicon from the site in mid-October. September 16, 2024 Patrick Jowett REC Silicon, a Norwegian producer of silane gas and silicon, has said it will make its first commercial shipment of ultra-high purity polysilicon from its newly restarted Moses Lake facility in Washington state in October.The company said the plant is “running well” and meeting production volumes for commercial shipments, with impurities reduced to customer acceptable levels.However, shipping has been delayed until mid-October due to a final qualification step by…

Molecular adjustments increase the efficiency of organic solar cells Organic solar cells (OSCs) offer a promising alternative to traditional inorganic solar cells, thanks to features such as tunable chemistry that allow scientists to fine-tune their properties for better performance. Researchers in Japan have now used this tunability to achieve higher energy conversion efficiency in OSCs. A recent study published in ‘Angewandte Chemie International Edition’ by researchers from Osaka University reports the development of a new organic semiconductor that surpasses the energy conversion efficiency of standard models. OSCs are lightweight, flexible and can be mass-produced at relatively low cost, making them…
