In the field of photovoltaics, intensive research is being carried out to continually improve solar cell efficiency. Increasingly, the focus is on tandem photovoltaics, in which high-performance solar cell materials are brought together in various combinations in order to use the solar spectrum even more efficiently when converting light into electrical energy. Fraunhofer ISE is now reporting a new record efficiency of 25.9 percent for a III-V/Si tandem solar cell grown directly on silicon. This cell was produced on a low-cost silicon substrate for the first time – marking an important milestone on the way to economical solutions for tandem photovoltaics. The Fraunhofer Institute for Solar Energy Systems ISE has been working for many years on multi-junction solar cells, in which two or three sub-cells stacked on top of another absorb different portions of the solar spectrum and convert it into electricity. Silicon is a suitable absorber for the infrared part of the spectrum. Several micrometer-thin layers of III-V compound semiconductors made of elements from groups III and V of the periodic table are deposited on top of silicon. These sub-cells efficiently convert the light from the ultraviolet, visible and near-infrared parts of the spectrum into electricity. III-V semiconductor solar cells

Soil Machine Dynamics Limited (SMD) has won a multi-million-dollar contract to supply a Quasar II, medium-sized work class ROV to PTSC GEOS & SUBSEA SERVICES CO., LTD., (PTSC G&S), a subsidiary of Petrovietnam Technical Services Corporation (PTSC). The Quasar is the second of its kind to be ordered by PTSC G&S, nearly a decade after the first ROV was purchased. Quasar II is a versatile all-around performer capable of survey, construction, and drill support operations. Once delivered to the oil fields in South East Asia, it will work alongside the existing SMD ROV, performing a range of operations, at depths of up to 2,500 metres. PTSC G&S have commissioned a high specification of options to compliment the Quasar II, including the most powerful tooling capabilities, a survey pod, and the latest instruments. The vehicle offers class-leading performance, tooling, instrument space and easy access for maintenance. The machine will also be mated with an SMD compact Tether Management System (TMS). The team at SMD will also provide training and mobilisation support. The training will employ the use of SMD’s simulator to allow ROV operators to train and rehearse for a range of subsea scenarios before launching and piloting the ROV for real.

A Cornwall Insight and Ionic Consulting report that was commissioned by The Department for the Economy NI was published by the department last week. The report – Future of Renewables in Northern Ireland – provided an assessment of the current state of renewables in Northern Ireland as well as modelling for future renewable scenarios. The commissioned report used extensive research on the outcomes of past policy, the current landscape of electricity in Northern Ireland as well as feedback from various stakeholders including national and local government, regulators and industry bodies. Cornwall Insight developed a high-level model to assess possible outcomes of different renewable electricity targets, including 70%, 55% and 40% by 2030. Key findings Although some onshore wind is likely to be created without subsidy support, it is questionable whether onshore wind would be able to meet renewable electricity targets of 55% or 70%. Therefore route-to-market support will be necessary. Without the development of new generation assets in this decade, Northern Ireland could begin facing serious security of supply issues towards 2030 and beyond. Diversity of technology is an important consideration from the perspective of both grid capacity and security of supply. The ambition of the targets will have a material impact

Malin Newbuild, a Scottish marine engineering company, is partnering in a groundbreaking project to lessen shipping’s environmental impact. Part of the Malin Group, and specialising in delivering complicated multidisciplinary design and build projects, the company is aiming to demonstrate that a vessel fuelled by renewable energy can lead to a revival of civil shipbuilding in Glasgow, Scotland's largest city. The alternative technology, known as FastRig, has been developed by Wiltshire-based Smart Green Shipping who have been in discussions with the Scottish Government and Scottish Enterprise about funding the demonstrator’s construction. This month, the International Maritime Organisation (IMO) revealed that greenhouse gas emissions from shipping rose by 10% between 2012 and 2018, largely due to a surge in the number of ships fuelled by liquefied natural gas. [1] Malin Newbuild director Ben Sharples said: “We believe there is a real opportunity here for Scotland to be at the forefront of rapidly developing innovation. Our work so far on FastRig has convinced us of its potential. “We are currently working with Smart Green Shipping to develop the concept with a view to delivering a full-scale, 40-metre-high test-rig that can be showcased to the world when COP-26, the UN's climate change conference, comes to Glasgow.” Smart Green Shipping’s founder, Diane Gilpin, said: “Shipping is the world’s sixth-biggest emitter of greenhouse gases.  There are 60,000 vessels in the
