All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency

Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

Taiwanese consortium develops easily recyclable solar module

The Industrial Technology Research Institute (ITRI) and United Renewable Energy (URE) have developed a solar panel that can be easily dismantled to simplify the recycling process. They claim 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.

Queensland council plots path from coal hub to green superpower

The Gladstone Regional Council has ratified an ambitious roadmap that will be used to help the central Queensland city navigate the transition from traditional coal and gas hub to a green hydrogen and renewable energy superpower.

New algorithm to identify underperforming strings in PV systems

German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.

JinkoSolar claims 23.86% efficiency for n-type, TOPCon monocrystalline panel

Chinese manufacturer JinkoSolar’s newest PV module has an efficiency rating of 23.86%. It is based on its TOPCon mono cell technology, which achieved a record efficiency of 26.1% in October, as confirmed by TÜV Rheinland.

DAH Solar releases 540-555 W solar modules with frameless frontside

China manufacturer DAH Solar offers four versions of its new panels, with power outputs ranging from 540 W to 555 W and efficiency ratings from 20.89% to 21.48%. The modules are reportedly ideal for steel rooftops with small installation angles.

Companies line up as Queensland plans renewables-led manufacturing boom

The Queensland government is forecasting a renewables-led manufacturing and jobs boom in the state with hundreds of Australian and international companies registering their interest in supplying the thousands of solar panels, batteries, wind turbines, and kilometres of transmission lines the state says it will need to deliver its $62 billion (USD 40 billion) energy transformation plan.

AGL breaks ground on ‘pioneering’ Broken Hill battery

Construction has begun on a 50 MW/50 MWh battery near the outback city of Broken Hill which will be equipped with advanced inverter technology designed to improve system strength in regional New South Wales and support increased levels of renewable energy generation in the area.

Rooftop PV performance during heatwaves

Chinese researchers have assessed the impact of residential rooftop PV arrays on energy use and surrounding air temperatures during extreme heatwaves. They found that panels with higher conversion efficiencies achieved the best results.
