IRENA’s 14th assembly underscores role of geopolitics, urgent need for action

The 14th assembly of the International Renewable Energy Agency (IRENA) last week in Abu Dhabi underscored the centrality of geopolitics and security in the current global energy landscape. The gathering also called for greater action to achieve the COP28 target of tripling renewables deployment by 2030.

Maxeon sues REC, Hanwha Qcells for alleged TOPCon patent infringement

Maxeon has filed two different lawsuits in the United States against Hanwha Qcells and REC over claims that the two manufacturers used an unspecified tunnel oxide passivated contact (TOPCon) solar cell technology.


Coupling heat pumps with roll-bonded photovoltac-thermal collectors

Researchers in Sweden have analyzed how roll-bonded PVT collectors can act as secondary heat sources in ground-source heat pumps and have found they provide a better performance than conventional PVT panels. Their techno-economic analysis also showed roll-bonded PVT systems can be up to 9% more expensive than conventional installations based on sheet and tube absorbers.

Researchers design tin-germanium-based perovskite solar cell with potential efficiency of 31.49%

Researchers in Malaysia have simulated a mixed cation perovskite solar cell integrating tin and germanium in the absorber. By modulating the perovksite layer thickness, they were able to achieve an efficiency ranging from 24.25 % to 31.49 %
