Beijing group creates official entity to guide China’s polysilicon capacity
Industry analysts say a new Beijing-based coordination platform created by China’s top polysilicon producers signals a turn toward managed capacity, as the sector tries to halt a steep price slide and mounting consolidation pressures.
GCL Technology forms $287 million entity to buy stake in Chinese rival
GCL Technology Holdings has set up a CNY 2.06 billion ($287 million) partnership to acquire a 42.5% stake in Inner Mongolia Xinyuan Silicon Material Technology, in a move that may point to emerging consolidation in China’s polysilicon sector.
Sunwafe secures land for 20 GW silicon wafer plant in Spain
Sunwafe says it has formally applied to reserve land in Asturias, Spain, for a 20 GW silicon wafer and ingot factory backed by Chinese capital, EIT InnoEnergy, and a €200 million ($232.6 million) Spanish government grant.
How to reduce ionic losses in tin-based perovskite solar cells
Researchers in Germany have developed a DMSO-free fabrication process for tin-based perovskite solar cells that dramatically reduces ion density – over tenfold lower than in lead-based devices – leading to improved stability.
The thermomechanical impact of plated copper contacts on heterojunction solar cells
UNSW researchers have found that annealing copper-plated contacts in heterojunction solar cells creates only localized stress. Their analysis also showed that, at typical annealing temperatures around 200 C, the probability of silicon fracture is very low.
Solar powers the warfighter
2026 Defense authorizations highlight the need for U.S.-made photovoltaics in satellites to compete with foreign adversaries, writes Rob Gardner, vice president, congressional and regulatory affairs, for the SEMA Coalition.
Solar Stewardship Initiative publishes guide for solar supply chain
The Solar Stewardship Initiative’s (SSI) new buyers guide targets forced labor risk, supply-chain transparency, and compliance readiness in global solar procurement.
Perovskite-silicon tandem solar cell with steric complementary design achieves 32.3% efficiency
Researchers in China developed a monolithic perovskite-silicon tandem solar cell using a steric-complementary interface design, achieving a certified efficiency of 32.12% and enhanced long-term stability. This strategy optimizes molecular fit in the perovskite lattice, improving both charge transport and device longevity.
TNO offers mass customization line for integrated PV applications
The Dutch research institute’s highly automated research line offers customized, flexible solar semi-finished PV products to partners developing integrated PV applications.
How the world’s sunniest region tackles solar module soiling, cleaning
Researchers studying PV panels in Chile’s hyper-arid Atacama Desert found that cemented soiling can cause annual energy losses of up to 9.8%. Their combined field and laboratory work shows that dry cleaning leaves residue that accelerates future cementation, making wet cleaning the more effective long-term strategy despite higher costs and scarce water.
