HJT

The Renewable Energy India (REI) Expo 2023 showcased TOPCon solar modules from almost all leading PV manufacturers in India, including Adani, Premier Energies, Waaree, and more.

Panasonic unveiled its new residential solar modules – including half-cut heterojunction (HJT) models, along with a home battery system and energy management device – at the recent RE+ trade show in Las Vegas.

REC has developed a new series of heterojunction solar panels with efficiencies up to 22.6% and an operating temperature coefficient of -0.24% per degree Celsius.

Continued innovation in PV cell technology will have major impacts as PV is deployed at “multi-terawatt scale” over the next two decades, says a global team of scientists.

An international research team has developed high-efficiency solar cells with a 21.59% efficiency rating by using an all-inorganic phase heterojunction approach. The team used an anti-solvent-free DHA method to produce high-quality, inorganic perovskite thin films, resulting in better device performance under ambient conditions.

The two companies are targeting to reach an annual production capacity of 20 GW by the end of 2025. Manufacturing activities are scheduled to begin in the second quarter of next year.

Helena Li, president of Trina Solar’s global cell and module business, spoke to pv magazine at the recent SNEC trade show in Shanghai about the PV industry’s oversupply challenge. Li said the company is considering opening a factory in Europe and expressed optimism about future cost and price declines.

Eco-dynamic Tech’s 1,000 W solar awnings for recreational vehicles (RVs) feature flexible heterojunction solar cells and can be customized with a range of color patterns.

Italy’s 3Sun, a unit of Enel Green Power, has developed new monofacial PV modules based on n-type heterojunction (HJT) G12 solar cells. The M40 series for rooftop applications has power ratings ranging from 440 W to 480 W and an efficiency of up to 25%.

The PV Evolution Labs (PVEL) 2023 Scorecard identifies 250 solar modules from 35 manufacturers as “top performers.”
