Technology and R&D

Netherlands based manufacturer Energyra this week introduced a new back contact module, which it has developed in partnership with Dutch research institute TNO and Germany’s ISC Konstanz. A prototype module was unveiled yesterday in a small presentation at Energyra’s factory in Zaandam, Netherlands. The company is targeting large-scale manufacturing by the end of 2020.

The South Korean PV manufacturers is bringing its three most powerful solar panels to Europe. All of them are based on its Q.antum Duo Z tech, which reduces the gaps between cells and drives up module efficiency by 4% in relative terms.

In the fourth and final article of a series, pv magazine editor Pilar Sánchez Molina analyzes with industry experts challenges and opportunities created by new panels with power output exceeding 500 W.

French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.

The Baofeng Group is building a 1 GW solar park which is hosting a goji berry plantation in the Binhe New District on the eastern banks of the Yellow River in the Ningxia Province. Around 640 MW have so far been grid-connected. Huawei is providing the inverters for the project.

A Chinese research group has developed a PERC cell on a commercial 180-μm-thick monocrystalline silicon wafer with a standard size of 156 × 156 mm2. The cell has an open-circuit voltage (VOC) of 0.677 V, a short short-circuit current (ISC) of 9.63 A, and a fill factor of 80.30%.

The South Korean government has released a new roadmap to support R&D activities in the solar sector. The document indicates the country’s solar manufacturing industry may be encouraged to opt for high-efficiency and expensive panels based on tandem solar cells.

An international group of scientists has discovered a ‘space charge’ mechanism that explains why certain metal oxides used as electrodes in lithium-ion batteries exhibit higher storage capacities than should be theoretically possible. The research, according to the group, will unlock new pathways to the development of more advanced energy storage systems.

According to the 2020 Global Gas Report by Snam, the International Gas Union and BloombergNEF, public policies are required to support clean hydrogen reach industrial clusters and to facilitate large-scale use. The authors of the report acknowledged the advantages of using wind and solar to directly power electrolysis, but they do not discard the possibility of using gas power with carbon capture storage. The experts of the three parties also identified barriers to remove for future development.

A new white paper by Alencon outlines the differences between PV-centric and battery-centric coupling.
