Fraunhofer ISE achieves 34.2% efficiency with III-V germanium PV module
Fraunhofer scientists have announced two efficiency records for III-V tandem modules. The team says its 34.2% efficiency III-V germanium PV module is the most efficient solar module in the world, while its 31.3% efficiency III-V silicon PV module is a record in its class.
ReNew Energy Q3 total income rises 48% year-on-year to INR 31.37 billion
The company also reported a 6.6-fold increase in net profit for the first nine months of FY2026.
Comparing safety profiles of lithium-ion, sodium-ion and solid-state batteries
New research finds that battery safety rankings are not universal but highly dependent on application scenarios, and shows that LFP batteries can emit high levels of hydrogen fluoride, challenging their reputation as the “safest” chemistry.
Silver-saving efforts ramping up in solar industry, says Heraeus
Rising silver prices are putting pressure on solar manufacturers, prompting greater focus on copper and other alternatives to reduce costs. Heraeus says it expects silver demand from photovoltaics to decline this year despite stable global installations.
Powertrac to set up 1 GWh BESS factory
Gujarat-based Powertrac Group has announced an investment of INR 600 crore to establish a 1 GWh containerized battery energy storage system (BESS) manufacturing facility. The facility will focus on lithium iron phosphate (LFP)-based battery pack assembly, along with in-house battery management system (BMS) development and integration.
Can sodium-ion beat Li-ion in portable power? Bluetti Pioneer Na gives it a try
The world of batteries needs alternative chemistries to skirt weaknesses with lithium-ion. Sodium-ion is a big hope, and in portable power, Bluetti’s new product shows promise, and limitations.
India’s FY2027 budget shifts focus from renewable deployment to manufacturing, but execution challenges persist, says Wood Mackenzie
Clean energy spending rises 40% to $5 billion as government prioritises CCUS, domestic supply chains and strategic manufacturing. However, execution delays and underutilisation of allocated funds could limit the near-term impact, according to an analysis by Wood Mackenzie.
Longi builds 27.25%-efficient back-contact solar cells with high-resistivity wafers
High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard wafers. Researchers from Longi and Sun Yat-sen University demonstrated that integrating in-situ edge passivation unlocks this potential, significantly boosting back-contact solar cell fill factor and efficiency.
Polysilicon transactions remain subdued amid buyer hesitancy
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
India’s blueprint for sustainable solar success
By embedding quality benchmarks into procurement and manufacturing incentives, policymakers are ensuring that India’s energy transition is durable, not disposable. The focus has moved from rapid installation to long-term reliability — a sign of sectoral maturity.
