Australia leads world as solar sets global generation record
A new report published by UK-based energy think tank Ember shows that solar was the world’s fastest-growing source of electricity generation in 2021. Australia leads the world in its uptake, with PV generating 12% of the nation’s electricity last year.
Switzerland plans winter bonus for PV systems with a tilt angle of at least 75 degrees
The Swiss Federal Council has the task of standardizing the incentives for renewable energy and has now started the related parliamentary process. A winter bonus for photovoltaic systems may be introduced in the future.
Longi achieves 25.47% efficiency for gallium-doped p-type heterojunction solar cell
The result, confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH), was achieved on a heterojunction solar cell based on an M6 wafer.
Growatt unveils new inverter for residential applications
The new device has an efficiency of up to 98.6% and a European efficiency of up to 98.1%. It features up to two maximum power point tracking (MPPT) inputs, with MPPT voltage ranging from 140-1,000V.
Tin perovskite solar cell with operational stability of over 1,300h
Scientists in Spain have built a 10.61%-efficient tin perovskite solar cell with improved open-circuit voltage and stability. The device was fabricated with formamidinium tin iodide (FASnI<sub3), sodium borohydride (NaBH4) as a reducing agent, and a bulky secondary ammonium cation of small size known as dipropylammonium iodide (DipI).
Ultrathin photovoltaic silicon membrane with 65% light absorption
A Dutch-British research group is developing a 1μm crystalline silicon membrane with a remarkable optical performance and a hyper-uniform pattern design. A simulation of the device was theoretically able to achieve an absorption equivalent photocurrent of 26.3mA/cm2.
