Technology and R&D

Swiss scientists have analyzed scenarios to predict the role of PV in the global energy mix by 2050 and have found that European entities expect a sharply higher compound annual growth rate than their Asian and North American counterparts. They also noted that the growth scenarios of the Intergovernmental Panel on Climate Change are more conservative than other predictions.

The device was developed by an international consortium through the EU-funded project Renewable penetration levered by Efficient Low Voltage Distribution grids (RESOLVD). The power electronic technology is claimed to be able to combine different storage technologies in a single electronic-based board interface.

The German manufacturer said the result was confirmed by the US National Renewable Energy Laboratory. The achieved efficiency is claimed to be a world record for a CIGS panel with an integrated series connection of 30×30 cm.

Scientists in Germany demonstrated a slot die coating process for large-scale production of perovskite thin-film solar cells that achieved a maximum efficiency of 20.83%. Using an additive, and experimenting to find the optimal concentration, the group demonstrated improved control over the crystallization process – crucial for developing stable, repeatable processing.

Canadian scientists have developed a way to improve the short-term models used to forecast the impact of snow on PV arrays. The parameters include the warming effect of irradiance on the backs of panels, thermal capacity, and irradiance through snow.

Spain’s Tranesol is setting up two energy communities that will be powered by 2.5 MW of agrivoltaics. The two facilities will be located in the Valencian Community, which is at the forefront for supporting projects for solar power sharing.

Scientists in the U.S. laid out the rationale behind new PV module testing specifications published last year, which aim to better take into account the role of temperature in various types of performance loss. They suggest a new ‘98th percentile’ approach to measuring module operating temperatures, which would offer system designers a better understanding of the module’s performance in a particular ‘micro-environment’.

A handful of companies are challenging Chinese control of a core material in lithium-ion battery production, before the electrification of transport truly kicks off the global battery boom. International Graphite, a Perth-based startup at the forefront of this effort, recently spoke to pv magazine Australia about the surprisingly collaborative race to feed global demand.

Altrex, a scaffolding and ladder producer in the Netherlands, has developed a new modular lift solution for solar panels. The system can raise one solar panel at a time and can be operated by a single installer using nothing other than a cordless drill, the company claims.

Edgehog secured the funds from Sustainable Development Technology Canada (SDTC). The special glass is hydrophobic and is claimed to be able to reduce the accumulation of dust and residue, thus reducing the need for maintenance.
