Solinteg has released new inverters with nominal power ranging from 1.5 kW to 3.3 kW, an efficiency rating of 97.5%, and a European efficiency of 97.0%.

A Chinese-Swiss research group claims to have overcome two major challenges for the development of flexible all-perovskite tandem solar cells – voltage losses and the deposition process for the cell’s functional layers. They built a device with a high open-circuit voltage of 2.1 V.

Allied Irish Banks will buy electricity from two solar parks that NTR is now developing. The power purchase agreement has a duration of 15 years.

GoodWe’s new hybrid inverters have efficiency ratings of 98.0% and European efficiency ratings of 97.5 %. They are available in five versions, with power outputs ranging from 15 kW to 30 kW.

A team of international researchers has simplified the deposition of thin film layers in the commercial production of TOPCon solar cells. Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique, they were able to achieve a power conversion efficiency of 22.8% in a 60-cell, 613 W TOPCon module.

Norway’s SINTEF has designed a heat storage system based on phase change materials (PCM) that can support PV generation and peak shaving. The battery’s container hosts 3 tons of liquid biowax based on vegetable oil and is now beating performance expectations at a pilot facility.

Australian manufacturer Greatcell has built a cell with roll-to-roll coating technology. It designed it without a hole transport layer (HTL) and used carbon composite back contacts, which offer excellent electrical conductivity.

Chinese energy giant State Power Investment Corp. (SPIC) has switched on a pilot facility at 4,000 meters above sea level. It plans to complete the solar park by September 2023.

Scientists in South Korea have used a triboelectric generator and an electrodynamic dust shield to develop a panel-cleaning system that can be activated by footsteps. They said the system can remove more than 70% of accumulated dust with the pressure of just 12 footsteps.

Aerocompact’s new CompactFLAT GS mounting structure can be installed 40 cm above rooftop surfaces, with tilt angles of 10 and 15 degrees. The company says the product is ideal for bifacial solar arrays and green rooftops.
