Proposed HVDC ‘macrogrid’ to transmit low-cost, renewable power in US
A grid-modeling company has proposed an underground high-voltage DC transmission overlay for the continental United States. It could potentially help to reduce climate pollutants and electricity costs, in addition to facilitating solar and wind deployment.
Taiwanese consortium develops easily recyclable solar module
The Industrial Technology Research Institute (ITRI) and United Renewable Energy (URE) have developed a solar panel that can be easily dismantled to simplify the recycling process. They claim that 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.
All-perovskite tandem solar cell with 27.4% efficiency, high voltage
A US-Canadian research group has built an all-perovskite tandem PV device with a record-breaking open-circuit voltage of 2.19 eV, which they achieved by reducing recombination at the electron transport layer.
Soft costs in US residential solar adoption
US residential solar demand is expected to ride a 10% compound annual growth rate, adding $6 billion in incremental growth by 2025, said Technavio. But soft costs like customer acquisitions remain relatively high compared to other solar markets across the globe.
