An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.

Private sector fossil fuel spending on exploration is drying up just as modest rises in clean energy investments are being observed. With stock market investors increasingly embracing renewables, the IEA has observed positive signals in its latest energy investment report, but warned we are still doing far too little to keep global heating at bay.

Module manufacturers have once again adjusted their prices upwards. This is already the third or fourth price increase in the last six months, and there is no end in sight, writes Martin Schachinger of pvXchange. But why is it so hard to achieve long-term, sustainable development in the global solar market, at least on the part of manufacturers? Few other industries are so turbulent, with constant swings between excess supply and bottlenecks, between price collapses and price rises – and always to the breaking point of the market. Yet again, planning security is out the window.

As PV manufacturing lines continue to get larger, keeping track of the measurement data that’s vital for quality and process control becomes an ever more herculean task. Flashing equipment supplier h.a.l.m. has developed a software solution that keeps all of this data in one place and provides operators with a real-time view of production line performance and quality. pv magazine caught up with Managing Director Michael Meixner to discuss the latest on big data in PV manufacturing.

In the first installment of a new monthly blog by IHS Markit, Edurne Zoco, executive director for clean energy technology, writes that high prices and increased freight costs are putting solar PV procurement teams under extreme pressure, particularly those teams with connection deadlines this year that were anticipating a more favorable pricing and logistic environment in the second half of 2021.

A German PV system owner has developed a simple solution intended at preventing the birds from nesting under the modules.

Last week, testing specialists PV Evolution Labs launched its latest Module Reliability Scorecard, which names more than 100 products from 26 manufacturers as top performers, after being put through their paces in extensive lab testing. This year’s scorecard reveals an increase in modules seeing at least one failure during the testing procedure, with newly added mechanical stress procedures causing the greatest number of failures.

A Swiss start-up has created a containerised movable PV system that is designed to be easily relocated to allow the use of solar energy in locations where a fixed installation is not an option. The solution is based on a racking technology which can include two racks able to host up to 30 solar panels.

The pursuit of higher conversion efficiencies is an eternal theme in the PV industry. Among all the links in the chain, cell technology is the most fundamental and decisive element. As we look beyond the established PERC technology, whether heterojunction or TOPCon will become the dominant “next-gen” solar cell among China’s manufacturing giants is emerging as a balancing act between incumbent and upstart, reports Vincent Shaw from Shanghai.

The 50 kW version of the new inverter features an efficiency of 98.6% and a European efficiency of 98.1%. It can be deployed with a decentralised approach, next to the PV modules, or centralised, at the grid connection point.
