Developed by an Italian manufacturer, the panel is available in three versions with a power output of 100, 120, and 240 W and has a weight of 5 kg. It is encapsulated in thermoformable plastic technical polymers and can be connected in series with other modules around the same post.

The mounting structure relies on a 5.8m long support rail that does not lie on the roof but is connected directly to a purlin placed below with self-drilling support screws.

The airplane is powered by 22 square meters of solar cells with an efficiency of up to 24% and 14 kWh of lithium-ion batteries. According to its creators, it can reach an altitude of 25,000m.

Scientists in Switzerland found that perovskites can be used to detect thermal neutrons emitted by radioactive devices. Taking advantage of several properties that also make the materials attractive for solar cell applications, the group was able to fabricate a novel device that could have various practical applications, including in energy generation.

Called SolFlex, the frameless panel is based on 22%-efficient solar cells and is designed for high, one-sided heat load. The standard product measures 100x100x2.9cm, weighs in at 3.4kg, and has a power output of 170 W.

A number of Fraunhofer institutes in Germany want to make green hydrogen more cost-competitive and are working to identify the best and most economical processes for the production of electrolysers. They intend to build a digital library of future-proof electrolyser manufacturing processes with which the investment costs and even the return on investment can be determined in advance depending on the planned production volume.

Spanish energy giants Repsol and Enagás are planning to build an electrolyser based on photoelectrocatalysis at an industrial complex owned by the oil company in Puertollano in 2024. The device receives direct solar radiation and with a photoactive material it generates the electrical charges that cause the separation of the water molecule into hydrogen and oxygen.

The performance of the solar cell contacts can be improved with laser-assisted current treatment. The process does not damage the solar cells but only optimises faulty semiconductor-metal contacts.

The panel is based on 14.9%-efficient organic PV cells with a surface of 1.1 cm2 that the same research group unveiled in September 2020. The solar cells were interconnected using laser structuring.

Photon Energy reported raised revenue from sales of electricity in the second quarter of the year, compared with 12 months earlier, but said grid hold-ups at 14.6 MW of solar projects Down Under had affected performance.
