Technology and R&D

The Australian Renewable Energy Agency (ARENA) has offered funding to nine Australian universities and research organizations to propel innovation in green hydrogen export.

The scientists have shown how the control of the molecular structure of a semiconductor polymer makes it possible to obtain a PV conversion efficiency of more than 10% for an organic solar cell.

The algorithm is said to be able to examine the relationship between weather forecast data and the projection of electric circuit parameters. Through this innovation, Purdue University researchers claim they can interpret the routinely collected maximum power point (MPP) time-series data, to assess the time-dependent “health” of installed solar modules.

Researchers from the Idaho National Laboratory have developed a new type of electrode for hydrogen production through electrolysis – water splitting. The team has used the electrode to demonstrate efficient hydrogen electrolysis at temperatures far lower than previously possible, which could lead to significant cost reductions in large-scale hydrogen production.

Researchers from Finland’s Aalto University and the Michigan Technological University, in the US, say they have demonstrated the cost per unit of power of black-Si PERC cells could fall 10.8%, despite an increase in cell processing cost.

A research team from South Korea’s Ulsan National Institute of Science and Technology has demonstrated a new process for the creation of organic solar cells. Using this method, the team has created cells with a conversion efficiency up to 12.01%.

Researchers from the University of California, Los Angeles, have set a new record 22.4% conversion efficiency for a tandem cell combining a lead-based perovskite layer with CIGS technology. The record has been confirmed by the U.S. National Renewable Energy Laboratory.

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.
