From tandem cell to double absorber for 34.45% efficiency

Scientists in the United States theorize that a ‘double absorber’ cell comprising two active thin-film layers within one cell stack could achieve impressive efficiencies, whilst eliminating many of the challenges inherent to the design of tandem cells. For now though, it’s only on paper.

Reducing solar’s environmental impact through ecolabels

It is undeniable that easy access to energy has provided tremendous benefits to humankind over the last several decades. But that access has come at a price – one that society only discovered after the fact. From the thousand-year half-lives of spent nuclear fuel to the climate change impact of fossil fuels, access to energy has had a high environmental cost. Renewable energy, especially solar, seeks to provide that same access without the environmental cost. But what is the environmental impact of solar panels and inverters? Is society once again seeking to benefit from an energy source without understanding and addressing its environmental impact? Not this time, writes Green Electronics Council CEO Nancy Gillis.

Tandem cells head outdoors

Scientists in Saudi Arabia headed outdoors to test the effects of the region’s high desert temperatures on the performance of small perovskite-silicon tandem cells in several different configurations. Their findings could offer new insight into selecting the best materials for long-term stability in the field.

French government considers cutting pre-2011 FITs

Financial newspaper Les Echos claims the government is mulling a renegotiation of historic feed-in contracts after the Court of Auditors in 2018 ruled the incentives too generous.
