Scientists have used a device based on the Duffing oscillator to solve the problem of low efficiency of PV systems at low input voltages at dawn and dusk. Its performance was reportedly better than that of a conventional DC-DC boost converter when boosting weak input voltages. October 14, 2024 Emiliano Bellini Researchers from the University of Yaounde I in Cameroon have proposed using the Duffing oscillator to amplify the output with very low voltage and low solar radiation levels at sunrise and sunset. The Duffing oscillator, or Duffing equation, is a differential equation used to model certain damped and driven…

The two Italian companies said their new modules use a fully recyclable sticker that can help improve aesthetics and turn the panels into billboards. The panels use 24% efficient interdigitated back-contact solar cells from Maxeon. October 14, 2024 Emiliano Bellini Italian PV module manufacturer Solbian and Italy-based startup Sunspeker have developed new solar panels for vehicle-integrated solar photovoltaics (VIVP) applications. The modules use customizable, fully recyclable stickerThat’s possible replicate high-resolution images while remaining permeable light. The images processed using Sunspeker’s proprietary process reportedly maintain a high degree of transparency. The adhesive film for the aesthetic covers is a thermoplastic material…

The UK solar industry was recently awarded 4.5 GWp-dc across 93 sites in allocation round 6 (AR6) of the Contracts for Difference (CfD) programme, the highest capacity since the 2014 CfD scheme started. The CfD scheme has been particularly beneficial to the sector. Solar energy projects were originally allowed to participate in the first CfD auction (AR1). However, solar was subsequently omitted in the subsequent AR2 and AR3 auctions. Solar returned to the AR4 allocation rounds in 2022, when sites with a total of 3.1 GWp were successful, followed by 2.7 GWp in the AR5 auction process in 2023. Taking…

Scientists in China have investigated the fracture strength of commercial G12 monocrystalline wafers through the 4-point bend test and found that the thickness of the wafer, the position of the silicon wafer in the silicon brick and the bend test direction are key parameters for developing future strategies. aimed at reducing fractures. October 14, 2024 Emiliano BelliniResearchers from Shandong University in China have investigated the fracture strength of commercial 210mm x 210mm monocrystalline silicon G12 wafers used for solar cell production and found that several strategies can be applied to produce large and ultra-thin silicon wafers and at the same…

October 10, 2024 Ev FoleyBy pv magazine AustraliaWestern Australian gas company ATCO Australia has delivered a test network distribution blend of up to 10% renewable hydrogen, produced by a solar-powered electrolyzer, to 3,000 homes as part of the Hydrogen Community Blending Project (HCBP).The Hydrogen Community Blending Project (HCBP) is a AUD 2.6 million ($1.7 million) initiative, building on successful blending tests from the Clean Energy Innovation Hub (CEIH) at ATCO’s Jandakot operations center. The…

NHPC Ltd. has issued a tender inviting developers to set up 1.2 GW of grid-connected PV projects, with an option for a further 1.2 GW under a greenshoe option. Bidders must submit their proposals by November 4. October 11, 2024 Uma Gupta Image: Adani Green EnergyBy pv magazine IndiaNHPC has launched a tender to select developers for 1.2 GW of grid-connected solar projects and up to 1.2 GW of additional capacity under a greenshoe option.The potential developers will build, own and operate the PV projects at locations across India.NHPC will buy and sell the solar energy to state-owned companies, distribution…

In a new weekly update for pv magazineSolcast, a DNV company, reports that Hurricane Milton’s impact on solar energy production will be minimal outside the southeastern United States because the system is rapidly moving offshore. October 11, 2024 SolcastHurricane Milton made landfall on Wednesday, October 9, bringing strong winds and heavy rainfall to much of the southeastern United States. However, the impact on solar energy production outside the region is expected to be minimal as the system quickly moves offshore. Outside of the Southeast, much of the continental US saw higher-than-average solar production in September, analysis using the Solcast API.Hurricane…

Telescopes could power isolated communities in Chile’s Atacama Desert New research published in ‘Nature Sustainability’ shows that integrating a renewable energy system for the AtLAST telescope in Chile’s Atacama Desert could meet 66% of the energy needs of the nearby city of San Pedro de Atacama, providing a dual solution would provide for both scientific and infrastructure. local communities. The proposed system would reduce dependence on fossil fuels, which would benefit the Chajnantor Plateau Observatory and surrounding residential areas by providing cleaner, renewable energy. The study suggests that similar energy solutions at other nearby telescopes could reduce fossil fuel use…

This week, Women in Solar Europe (WiSEu) gives the voice to Sofie Graunbøl, Technical Sales and Sustainability Lead at the Danish Solar Polaris. She explains that solar installation is a male-dominated segment because many of the practices related to installation are based on men’s physical strength, making it more difficult to employ women. “This is an important issue that needs to be addressed so that the sector can improve,” she says. October 11, 2024 Women in Solar Europe (WiSEu)The solar industry, which is often seen as male-dominated, can benefit greatly from diversity. When women are involved in creating processes, asking…

Streamlined perovskite solar cells offer the path to cheaper, more efficient energy Researchers from the City University of Hong Kong (CityUHK) have developed a new manufacturing method that improves the efficiency, stability and affordability of perovskite solar cells, moving them closer to commercial viability. This study, published in ‘Science’, highlights how a simplified device structure designed by the CityUHK team could pave the way for future industrial-scale production of perovskite solar cells, improving their reliability and reducing costs. “The improvements in the stability and simplification of the manufacturing process of perovskite solar cells represent an important step forward in making…
