Gallium arsenide solar cell achieves 23.1% efficiency via electrochemical porosification

An international research group has utilized a new porosification technique to build gallium arsenide (GaAs) solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost thanks to the reuse of germanium.

Canada’s largest behind-the-meter solar project

Construction has begun on two solar projects in Alberta, one of which will include a flow battery energy storage system.

Swedish battery manufacturer to open factory in Canada

Northvolt Six will use a circular economy approach in its 60 GW/h of annual cell manufacturing in Quebec, assembling batteries for the U.S. automotive market.

U.S. and Canada to spend $12 trillion on renewables and grid by 2050

The intrinsic efficiency of renewables will lower the overall cost of energy from 4% of GDP today to about 2.5% by 2050, said a report from DNV.

Accelerating heat pump adoption in Canada

The Canadian Climate Institute released a report that details how to unlock lower-cost heating and cooling in Canada, outlines barriers to adoption, and makes recommendations for streamlining the loan and grant application process.

Solar for water deionization

Scientists in Canada have combined PV power generation with water purification based on capacitive deionization (CDI), which is claimed to have low operational cost, enhanced energy efficiency, and less water rejection than conventional purification techniques. The solar-powered system prototype is able to produce more water than a conventional CDI system on a sunny day.

Solar-powered sensors for wildfire detection

An AI-powered sensor was developed by Dryad Networks to detect wildfires and alert first responders.

To achieve net zero energy status, solar-powered buildings should not exceed 10 floors

Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17 to 28 kWh/m2a.
