Chinese institute unveils 26.1%-efficient perovskite PV cell with new additive

The Chinese Academy of Sciences said this week that its researchers have fabricated homogenized perovskite films that could increase the efficiency and stability of perovskite solar cells. The scientists said they addressed the typical phase segregation issue that inevitably takes place inside perovskite films and affects both the power conversion efficiency and thermal stability of perovskite PV devices. This …

Longi claims world’s highest efficiency for p-type, indium-free HJT solar cells

Longi has revealed that it has achieved power conversion efficiencies in mass production of 26.56% for a gallium-doped p-type HJT solar cell and 26.09% for an indium-free HJT cell, both based on M6 full-size monocrystalline silicon wafers. The results have been confirmed by ISFH. “Addressing the long-term pain point of HJT cells, Longi’s R&D team focused …

High electricity rates push US homeowners to consider solar

The cost of electricity is rising in states across the nation. That coupled with the increased frequency of long power outages is pushing more Americans to consider solar. Homeowners are challenged to stretch their budgets now with inflation, supply chain challenges, and rising interest rates. Rocket Solar’s study asked homeowners which home essentials they are spending more …

How to get to 100% emissions-free electricity

There are many paths to reach 100% emissions-free electricity. The US Department of Energy’s National Renewable Energy Laboratory (NREL) has released “Examining Supply-Side Options to Achieve 100% Clean Electricity by 2035,” which looks at multiple scenarios. NREL concludes that a 90% clean grid will have a low incremental cost, and that it can be built …
