Modules & Upstream Manufacturing

U.S. decarbonization goals hinge on scaling up heterojunction solar cell tech

HJT technology could fill an innovation gap in the residential and commercial rooftop PV market, and boost U.S. solar leadership through domestic manufacturing of cells and modules.

The Good, the Bad and the Ugly: defects in perovskite solar cells

Scientists in the UK delved deep into the structure of a perovskite solar cell, looking to understand the complex relationship between the materials that make up the perovskite layer, and the role of different defects in both limiting and improving performance. The findings could allow for new perovskite materials that are specially structured to maximize PV performance.

‘Italy needs own supply chain to navigate raw materials crisis’

Paolo Rocco Viscontini, president of trade association Italia Solare, has spoken to pv magazine about the challenge high system prices pose to Italian solar and discussed the nation’s ‘super bonus’ tax deduction, which remains the main market driver for small scale arrays.

The weekend read: Cloud looms over PV’s silver lining

Should heterojunction solar technologies be temporarily shelved? Could copper plating replace screen-printed silver conductive surfaces in cells? Why are tandem cells a likely successor to PERC? Brett Hallam recently sat down with Natalie Filatoff in Sydney to explain the findings of a new study by UNSW that sought to answer these controversial questions.

Chinese PV Industry Brief: Solar module prices drop for the first time in the past six months

Furthermore, polysilicon manufacturer Daqo will increase investments in its plans to expand capacity and Canadian Solar closed a strategic co-operation agreement with battery giant CATL.

Semi-transparent solar module for greenhouse applications

Manufactured by scientists in Italy, the 3.88%-efficient organic solar panels are able to filter the light from the roofs of greenhouses. They are also capable of supplying a portion of the electricity required to power the greenhouse’s temperature and humidity sensors.

ITRPV: More work needed to process 210mm wafers

In an update to its annual International Technology Roadmap for Photovoltaics, German engineering association VDMA discusses the readiness level for various technologies in PV cell and module manufacturing, finding that more process development is needed for 210mm wafers – the largest format currently on the market – to match the throughputs that will soon be achievable with smaller formats including 182mm.

Hunting the sun with Harris hawks optimization algorithm

An Iranian-Canadian-based research group has conceived a nature-inspired algorithm to estimate the model parameters of PV systems. The proposed tool mimics the exploring, exploiting and attacking strategy of the Harris hawk, a bird of prey species that cooperates when hunting.
