High hopes for heterojunction
In recent months, China’s Risen Energy has posted impressive module efficiencies, closing in on 24%, with its hyper-ion series. The company will ramp up to large-scale production of these heterojunction products in the first half of 2023, and pv magazine recently caught up with Risen Energy’s Chief Information Officer Terry Wu to discuss this, as well as the company’s work on energy storage projects.
3D/2D perovskite solar cell treated with substituted PEAI hits 23.08% efficiency
An international research team has fabricated a quasi-2D perovskite solar cell with a special kind of phenethylammonium iodide (PEAI) salt to enhance hole extraction. The result is a 23.08%-efficient device that is also able to retain 95% of its initial efficiency after 900 hours.
Biden to maintain US solar tariff pause with veto
US legislators are moving to restore tariffs for the shipment of solar components from four major Southeast Asian nations, but US President Joe Biden will veto the move and maintain the pause on tariffs.
Concentrating photovoltaics for agricultural applications
A research team has studied the potential of using concentrating photovoltaics in agriculture and found that it offers advantages in terms of energy yield and de-shading compared to conventional photovoltaics. However, the higher costs must be carefully considered.
