Focusing on technology, the Photovoltaics International journal is specifically designed for the PV supply chain, including materials, components, equipment, manufacturing and large-scale utility installation. This in-print business-to-business publication influences the purchasing decisions of PV manufacturers, energy utilities and integrators by associating solution providers with high quality and independent technical papers.

Photovoltaics International Volume 43

Volume 43

The PV industry continues its technological advance and downstream markets continue to grow, with the two elements remaining intrinsically linked. If this edition is an indication that technological advances are continuing to shape the industry and drive down the cost per-Watt to record lows, then we are set for many years of continued growth. Our annual in-house analysis of the R&D spending trends of 21 PV manufacturers in this edition highlights the second consecutive year of combined expenditure topping the US$1.0 billion mark, with the LONGi Group setting a industry record of US$182.74 million of expenditure in 2018. One of the first to transition to SHJ technology was the Russia-based Hevel Group. A paper from Hevel in this edition is notable for detailing all the processing steps required for successful SHJ production. Fraunhofer ISE demonstrates latest advances in PERC-based shingled solar cells. Edition 43 continues its own series of Industry 4.0 papers, with researchers from ISC Konstanz highlighting the role and impact of digitalization and self-learning concepts in PV manufacturing. A paper from ISFH that details the processes and the key importance of accurate solar cell measurement, especially, as noted in the last edition, in light of the swathe of solar cell conversion efficiency records already seen in 2019.

The PV Tech Power journal is focused on the challenges and solutions concerned with designing, building and operating commercial & utility scale PV power plants. It addresses technology and business issues which impact on reducing LCOE and protecting ROI.

PV Tech Power Volume 20

Volume 20

Welcome to the latest edition of PV Tech Power. This is a special issue for a number of reasons. The journal has now been running for five years with a growing roster of industry experts sharing in-depth knowhow on everything from contract law to the pitfalls of east-west module layout. It’s also a special issue for us as it is the tightest marriage yet of PV Tech’s decade-plus of solar industry coverage and the expert analysis and reporting of our sister site Energy-Storage.News. Our 19-page special report in this issue explores both the accomplishments of the energy storage sector and the ongoing challenges. Fittingly, Andy Colthorpe, editor of Energy-Storage.News, sets the scene (p.20). Looking ahead we investigate the growing trend for DC-coupled storage systems in the US in particular and at all scales (p.29). VDE’s Jan Geder meanwhile, looks at the very necessary technical work going on to ensure that the energy storage boom is both bankable and insurable (p.40). Recycling is another area where the storage sector has more to do. The consultancy firm Li-Cycle explains why a battery powered future means creating recyclable products now, or risk jeopardising the tech’s positive legacy (p.45). Our regular Storage & Smart Power section also includes a feature from UK editor Liam Stoker taking a deep dive into the role of storage and other technologies limiting the damage done by a major blackout in the UK this summer (p.114). This edition is not universally focussed on storage however. PV Evolution Labs’ Michael Mills-Price and Jenya Meydbray discuss their inverter scorecard report. As the main driver of corrective maintenance they argue the case for comprehensive quality benchmarks in inverters (p.94). José Rojo looks at two of Latin America’s most vibrant markets, Mexico and Brazil. We also have an update on Taiwan’s solar market as the focus shifts from pure manufacturing to deployment as well (p.59), a closer look at the impact of the bifacial trade tariff exemption in the States (p.48) and much more.
