A Spanish-Italian research group was able to improve the efficiency and stability of a standard perovskite solar cell by adding nitrogen-doped carbon dots as an additive. The carbon dots were then blended with the perovskite precursor solution at two different concentration levels and both were deposited by spin coating on the perovskite layer.

Gamesa Electric’s new Proteus PV inverter represents an upgrade over the previous Gamesa Electric 3X series. It has an output of up to 4,700 kVA and is compatible with DC/ESS interfaces for the connection of storage energy systems.

German electrical equipment provider AEG is launching a shingled solar module for residential and commercial installations at this year’s Smarter E event in Munich, Germany.

Mondragon will install a 100 MW manufacturing line in the third quarter at Solarge’s factory in the Netherlands. Production is scheduled to start by the end of this year.

The proposed system architecture is claimed to offer more stability compared to conventional floating structures and reduces by up to 93% the contact area of the system with the water. The first system prototype was recently developed on a water reservoir in Alava, in the northeastern territory of the Basque Country.

The Spanish authorities applied solar curtailment for the first time on Easter Sunday, when power generation exceeded demand and the wholesale electricity price went from €168.50 ($182)/MWh to just €3.70/MWh.

A Spanish-Italian research group has developed a solid-state thermal-to-electric energy converter based on hybrid thermionic-photovoltaics (TIPV) for different applications. It consists of a three-terminal TIPV device made with a tungsten (W) thermionic cathode, a PV/anode structure made of an indium phosphide (n-InP) anode, and a photovoltaic cell based on indium gallium arsenide (InGaAs).

Adolfo Suárez Madrid–Barajas Airport in Madrid will open a new 120 MW PV plant as part of a bigger, €350 million ($380.8 million) solar deployment plan.

Scientists in Spain have developed a new heat pump that can produce 6.49 kWh of heat for each kilowatt-hour of power it consumes. The device could generate hot water at a temperature of up to 75 C.

Ikea’s holding company, INGKA Holding, will invest €340 million ($371 million) to acquire nine PV systems from Enerparc. In the future, Ikea said it will work with Svea Solar to sell residential PV systems.
