‘The first terawatt of solar PV installed globally took some 70 years to achieve, while the second will likely take only three’
Leading solar researchers from around the world are meeting for the first time in four years in Milan, Italy, for the 8th World Conference on Photovoltaic Energy Conversion (WCPEC-8). The first morning has seen prestigious awards bestowed on two scientific leaders and inspirational discussions as to how the “second terawatt” of solar can be installed globally in just a handful of years.
Solliance hits 30.1% efficiency on perovskite/silicon tandem solar cell
The Solliance consortium achieved a 29.2% record efficiency for the solar cell in November 2021, from just 28.7% in March 2020. In recent months, it increased the perovskite cell for the tandem device from 17.8% to 19.7%.
The weekend read: A year of solar uncertainty in the US
The supply of PV modules to the United States has been challenged by potential tariffs on goods shipped from four Southeast Asian nations that provide 80% of US solar panels. The disruption stems from an ongoing investigation into allegations of antidumping violations. US President Joe Biden has halted tariffs related for two years, but challenges still loom, reports pv magazine USA’s Ryan Kennedy.
