Technology and R&D

The 5x5cm device was developed by a Japanese research group. The thickness of the perovskite films was increased to reduce defects and pinholes and this was achieved by adding ammonium chloride to the lead iodine solution used in the formation of the films. The device was able to work for 1,600 hours at more than 80% of this efficiency.

Companies from a dozen EU member states will commit the public funds in a bid to come up with novel battery chemistries and production methods as well as recycling and circular economy innovation.

Six new arrays with a combined capacity of 120 kW will be installed on the International Space Station starting from this year. The panels will be brought to the station with the SpaceX Dragon cargo spacecraft during three resupply missions. The installation of each solar array will require two spacewalks.

A researcher from the NREL has set up a series of datasets of measured ground albedo values using measurement network data in the U.S. and data contributed by the PV industry. The measured albedo datasets are intended to help developers of ground-mounted PV projects in making a choice between monofacial and bifacial panels.

Solar-linked projects will be developed by domestic firm Augwind and will feature underground storage tanks. One of the systems will be built by French energy giant EDF and will feature a 20 MWh compressed air storage system and 5 MW solar array.

IHS Markit is predicting the world will add 30% more solar capacity this year.

The interconnection tech, developed by scientists at the Belgian research institute Imec, is based on a three-dimensional fabric of encapsulant with incorporated horizontal and vertical solder‐coated metal ribbons. Mini solar modules built with the proposed technique have provided interesting results in tests for thermal cycling reliability, showing very limited degradation.

Scientists from Israel and France have proposed a PV-plus-thermal-storage (PV-TS) concept that may be applied in regions with low direct solar beam radiation and high levels of global solar radiation. They estimated that the grid penetration rate of a large scale PV plant, when combined with molten salt storage, may rise from around 30% to up to 95%.

Two French companies have collaborated on the development of the Osmo-Watt system, which is powered by solar panels. They claim that the technology can produce up to 100 cubic meters of drinking water per day.

Developed by scientists from German research institute Fraunhofer ISE, the silicon-carbide device claims 98.4% efficiency and could be used in utility-scale photovoltaic projects.
