Leading solar manufacturer and solution provider JA (previously JA Solar) has signed an ecosystem partnership memorandum with Medisheng Technology to develop solar-powered desalination solutions for coastal and island applications.
Under the agreement, JA will provide integrated solar PV, energy storage, and smart energy solutions, while Medisheng will contribute seawater desalination and brine treatment technologies. The partners aim to develop renewable energy-powered desalination systems for coastal and offshore regions.
JA said the collaboration is intended to reduce the high energy consumption, carbon emissions, and operating costs associated with conventional seawater desalination.
China recently issued an action plan calling for greater use of renewable energy in seawater desalination (see China Solar PV News Snippets).
Perovskite solar technology developer SunFlex New Energy and its research partners have published two studies in Nature addressing efficiency and stability challenges in perovskite solar cells.
The first study introduced a TDB light-conversion additive to suppress halogen segregation in perovskite-organic tandem cells, achieving a certified steady-state efficiency of 28.04% and retaining 90% of initial performance after 625 hours under ISOS-L-1 testing.
The second study developed a D-A-D electronic resonance molecular structure (FMTPA-CPA) to improve the stability of self-assembled monolayer interfaces. The technology achieved efficiencies of 27.69% for rigid devices, 26.64% for flexible devices, and 23.63% for a 15.64 cm² module. The devices retained more than 98% of their initial efficiency after 720 thermal cycles between -40°C and 85°C.
SunFlex recently signed a strategic cooperation agreement with Nayuta Space to jointly develop a 400 m² rollable flexible perovskite solar sail for satellites (see China Solar PV News Snippets).
The China Photovoltaic Industry Association (CPIA) has released a new group standard, titled General Principles of Cost Accounting Models for the Photovoltaic Industry, which establishes a unified cost-calculation framework across the PV supply chain.
It standardizes cost accounting methods, calculation scopes, and coefficients for polysilicon, wafers, cells, and modules to improve consistency across the industry.
CPIA said the framework is intended to support more rational pricing and complement existing energy consumption and safety standards as the industry continues to address pricing pressure.
China is set to enforce revised national energy efficiency standards covering polysilicon, monocrystalline silicon, PV modules, and inverters from next year (see China Tightens Energy Standards For Solar Manufacturing).
China's Ministry of Industry and Information Technology (MIIT) has launched a national program to develop zero-carbon factories, outlining decarbonization targets for manufacturing facilities and data centers.
The initiative requires participating factories to achieve a minimum non-fossil energy consumption ratio of 30%, with a long-term target of at least 95%. Facilities consuming more than 5 million kWh of electricity annually must source at least 35% of their electricity from physical non-fossil power.
The program also targets reducing carbon intensity from 1.8 tons of CO₂ per ton of standard coal to 0.2 tons or less. Provincial authorities are required to submit their first batch of project recommendations by August 15, 2026.
China's National Energy Administration (NEA) has launched the China Green Electricity Certificate (GEC) Price Index to provide a national pricing benchmark for the green certificate market.
Using January 2025 as the base period, the index is calculated from nationwide GEC transaction data. It will be updated monthly to improve market transparency and price discovery.
According to the NEA, the index is intended to support more transparent certificate trading and strengthen links among the electricity, green certificate, and carbon markets. It also aims to provide a clearer reference for accounting of renewable energy investment and non-fossil energy consumption.
The NEA recently expanded the GEC system to include off-grid renewable energy projects (see China Solar PV News Snippets).
