Technology and R&D

Research conducted over several years by scientists at the Massachusetts Institute of Technology (MIT) demonstrates that air pollution in cities can put a dampener on the performance of PV panels which, if not taken into account, can threaten a project’s viability.

Module degradation tests are essential not only for effective plant operations, but also to ensure an optimum ROI. However, fixed laboratories, where such tests are usually carried out, involve transportation issues, while it is not always economically feasible to send in mobile laboratories. So how can degradation in these instances be measured? Leonardo Enrique Pérez Abreu, Technical Manager of the Testing & Optimization department at Enertis discusses this issue.

German company, Geltz Umwelt-Technologie has developed an advanced recycling plant, which it says could recover up to 95% of the materials in a module for reuse. With funding from the EU’s Horizon 2020 project, the company is planning a pilot facility that could recycle up to 50,000 silicon based PV modules per year.

By double stacking a perovskite-silicon solar cell and using the cell in a glass-on-glass bifacial solar module, scientists model that a 30-36% efficient solar module can be attained.

The Stuttgart-based industrial group wants to work on technology development and production with the British fuel cell manufacturer. Bosch considers highly efficient fuel cells an important step forward in the energy transition.

As the global EV market grows, manufacturers are seeking new revenue streams for used EV batteries. Applications in grid and residential storage systems have become popular. The market for second-life EV batteries is expected to reach $4.2 billion by 2025.

When pioneering and award-winning solar researcher Stuart Wenham passed away suddenly shortly before Christmas last year, some in the PV industry may have wondered what would become of his research into the role of hydrogen in crystalline silicon cells. His daughter, Alison Ciesla is answering that question alongside Wenham’s former team at UNSW, advancing its work into the crucial role of hydrogen in the degradation of silicon cells.

Arizona State University researchers have determined that a 32% efficient perovskite-silicon tandem cell could produce electricity at the same price as cutting-edge 22% efficient panels in the most cost-competitive of situations

Enel Green Power North America and Raptor Maps will develop AI-based drones to reduce O&M costs. Kicking off this month, the project will see its first batch of 30 field workers trained by the end of the year. Both companies already have the relevant technology in their portfolios.

New developments in inverter architecture suggest that string inverters have charged forwards again to take on the challenge and kick central inverters off the throne in the utility-scale market. Hardware design innovations allowing to cut down BoS capex and improve efficiency of the plants might push string inverters further to take more space in the utility-scale market place.
