A delegation from Chinese module maker Longi met with officials from Algeria’s Ministry of Energy and Mining last week to discuss cooperation that would support Algeria’s domestic solar market, including a solar manufacturing facility.

Longi said it has achieved a 27.81% efficiency rating for a hybrid interdigitated back contact, as confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).

The Solar Solutions Amsterdam 2025 trade show highlighted the shift in Europe toward smarter, scalable energy systems, showcasing innovations in residential and commercial solar technology as demand for integrated, flexible solutions continues to grow.

Longi has released a back-contact solar module with 24.8% efficiency, featuring a power output of up to 670 W and a temperature coefficient of -0.26% per degree Celsius.

JinkoSolar has sued Longi for alleged patent infringement in Australia, its third legal action against the company this year, following filings in China and Japan. The lawsuit, filed in the Federal Court of Australia, claims that Longi used an unspecified solar cell technology.

Longi has issued a profit warning for 2024, forecasting a net loss of up to $1.11 billion – a sharp decline from last year’s profit of $1.42 billion.

China’s Longi Green Energy has set a new world record for crystalline silicon solar module efficiency with its independently developed hybrid passivated back contact (HPBC) 2.0 module, achieving a conversion efficiency of 25.4%, according to a certification report from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).

Indian PV manufacturers are looking beyond tunnel oxide passivated contact (TOPCon) solar. Back-contact (BC) devices are an enticing prospect but many feel the technology is not mature enough. Uma Gupta considers the cost, yield, and reliability challenges that BC solar has to overcome.

European industry association PV Cycle estimates a 10 MW solar site will eventually produce 700 tons of waste material. It is becoming increasingly clear that PV modules need end-of-life protocols – for the technology and material processing, and the regulatory environment.

Shifting requirements for supply chain traceability and carbon footprint disclosure, along with solar oversupply and unsustainably low module prices, have made 2024 a challenging year for PV manufacturers. Despite these obstacles, the industry remains committed to its crucial role in the global energy transition. pv magazine recently spoke with Haimeng Zhang, chief strategy and environmental, social, and corporate governance (ESG) officer at Longi Green Energy, about how the sector is preparing to meet these challenges.
