Technical Papers

One year after the Inflation Reduction Act was passed, growth of community solar is expected to accelerate in the coming years thanks to federal help but also at state-level with states passing or improving new legislation. PV Tech Power Reporter Jonathan Touriño Jacobo looks at three different cases: California, Ohio and Minnesota, and investigates the challenges community solar still faces.

PV Tech Power Reporter Jonathan Touriño Jacobo looks at how the Inflation Reduction Act could help in redeveloping closed-down US coal assets to host solar PV projects.

Technological improvements contribute to enhancing the already high attractiveness of SHJ shingle technology, and to close the gap with industrial, economic and sustainability requirements usually considered for large-scale deployment of such panels.

Martin Pochtaruk, President of Heliene, Inc. on the challenges and opportunities of building out the domestic PV supply chain in the US.

Our EpiNex™ wafers enable higher efficiencies, lower costs and reduced carbon emissions in wafer manufacturing by more than 70% when compared with the conventional Czochralski process in regions that rely on coal-based electricity. NexWafe’s innovative and unique technology creates the opportunity to profitably manufacture ultra-low-carbon green solar wafers.

We develop a novel manufacturing process sequence for polysilicon on oxide (POLO) IBC solar cells by applying a local PECVD SiOxNy/na- Si deposition through a glass shadow mask to form the structured carrier-selective n-poly-Si emitter in a single process step.

Lena Dias Martins explores the UK government’s Contracts for Difference scheme which supports the country’s move to a zero-carbon economy.

Jason Kaminsky, CEO, kWh Analytics, on how renewable asset owners and their insurers are adapting the way they assess risk from natural catastrophes and extreme weather events.

In this paper, three generations of silicon heterojunction (HJT) solar cell technical routes in China are reviewed. We define the structure of HJT cells with an amorphous silicon thin film on two surfaces of a monocrystalline-silicon (c-Si) wafer as HJT 1.0, which is the first generation of HJT.

Tom Kenning looks at the rise of solar power in Texas, a US state better known for its role in the oil and gas industry, where a beneficial tax regime and an abundance of project land work in favour of building out solar power generation.
