In the field of organic photovoltaics, researchers are working hard to further increase the solar cell efficiency. New materials obtained from synthetic organic chemistry have enabled significant efficiency increases in recent years. Maintaining the efficiencies achieved in the laboratory on tiny solar cells is often a challenge when the cell area becomes larger. Now Fraunhofer ISE together with the Freiburg Materials Research Center FMF of the University of Freiburg has achieved a record efficiency of 14.9% for organic solar cells with an area of at least 1 cm². This marks an important step for this cost-effective technology on its way to application maturity. The Fraunhofer Institute for Solar Energy Systems ISE has been working on organic solar cells and modules in close cooperation with the Freiburg Materials Research Center FMF of the University of Freiburg for many years with the aim of further developing this technology together with industry partners and making it available at low cost. The principle research focus is to use cost-effective and environmentally friendly materials as well as to develop upscaling methods using roll-to-roll processes enabling solar modules to be produced in a similar manner as films. Organic photovoltaics has special properties that enable numerous new fields of

Mammoet is delighted to announce it has won two awards at the European Association of Abnormal Road Transport and Mobile Cranes (ESTA) Awards of Excellence 2020. Mammoet won the ‘Safety’ award for its reverse signaling solution, which creates safer reversing conditions when trailer drivers are working with a spotter. Mammoet then won its second award of the afternoon for the design, build, and debut of its revolutionary technology, Trailer Power Assist (TPA), in the ‘Innovation: end user’ category. ESTA announced the winners on 24 September 2020 during a virtual ceremony, after the event – originally due to take place six months earlier – was postponed because of the coronavirus pandemic. Safety ESTA Award Mammoet won its first award of the afternoon in the ‘safety’ category because of its reverse signaling solution. While reverse alarms have long been a safety feature when trailer drivers are reversing, they can obstruct communication between the driver and their spotter when operating in a noisy environment. To overcome this challenge, Mammoet’s engineers designed an alarm shutoff button that allows the spotter to turn the reverse alarm off to enable a clearer communication channel with the driver, while simultaneously triggering two flashing orange LED lights on the back of the

The “Hof van Twente” solar energy park (9 MWp) is already operational The “Hoogeveen” solar project (24 MWp) is expected to be commissioned in Q4 2020 With installed plants producing over 100 MW, BELECTRIC is one of the leading builders and operators of PV power plants in the Dutch market Kolitzheim (Germany) – The German solar power specialist BELECTRIC continues to expand its presence in the Dutch solar market: With the completion of the “Hof van Twente” solar energy park (over 9 MW), the EPC (engineering-procurement-construction) provider BELECTRIC has achieved a successful on-time launch and connection of the first of two projects for its German client Kronos Solar. The photovoltaic system in the Province of Overijssel consists of over 23,000 solar cells and produces enough climate-friendly green energy to supply around 3,000 households per year. In addition, BELECTRIC is currently constructing the “Hoogeveen” solar plant in the Province of Drenthe. This will have a capacity of around 24 MW when it commences commercial operations in the fourth quarter of this year. BELECTRIC will also assume operations and maintenance services for both solar plants on behalf of Kronos Solar. “By the end of 2020, we will have built a solar capacity of more

Reliance on publicly available solar datasets may hold back development and operation of profitable solar projects in Japan Solargis sees growing demand for high-resolution, validated solar data from international and domestic developers Japan, 23rd September – Japanese solar developers and operators need to invest further in high quality resource and forecasting data in order to ensure profitability, and sustain growth in Japan’s rapidly developing solar market. This is according to data and software architects for bankable solar investments, Solargis, which has confirmed that almost 300 solar projects in Japan have now been financed, developed or optimized using its datasets. As the cost of solar PV generation continues to fall and Japan looks to diversify its energy mix, the Japanese solar market is set for strong growth in the coming years. To maintain market momentum and sustain the appetite of investors, it is essential that both domestic and international solar firms are able to build profitable solar portfolios. A cornerstone of successful project financing, development and operation is accurate, high resolution solar data. Solargis has highlighted that, for Japanese projects supported by the current Feed-in Tariff (FiT) scheme, a 1% increase in Global Horizontal Irradiance (GHI) could translate into a revenue increase of 240,000-600,000 JPY/MW/year.

Hamburg, 22nd September 2020 – Sharp today announces the addition of a new 440W monocrystalline silicon photovoltaic (PV) panel to its half-cut cell portfolio. Available today, the NU-JD440 has a module efficiency of 19.9% and uses 144 M6 wafer size half cells. This decreases the balance-of-system costs per watt-peak installed across the whole BOS component range, providing customers with lower levelized costs of electricity (LCOE) and a higher return on investment. The new module features 9 BB (multi busbar) technology using round ribbons which increases the power gain from each cell and making them less sensitive to microcracks, offering higher module reliability. A low temperature coefficient of -0.347%/°C for the power output ensures higher performance at high environmental temperature, which becomes increasingly important due to climate change and the resulting rise in temperatures. In addition, the NU-JD440 module uses 1,670mm cables which enable trouble-free wiring in landscape installations and also allows for leapfrog wiring when installing in portrait, helping to further reduce system costs. All Sharp half-cell modules have three small junction boxes instead of just one, each fitted with one bypass diode. These junction boxes are transferring less heat to the cells above and in turn boost the longevity of the panels and the
