New research sheds light on voltage deficit in selenium solar cells
An international research team has investigated the impact of intrinsic point defects in selenium solar cells and has concluded that these defects are not responsible for voltage deficit. The scientists rather believe interfaces and extended defects may be the cause of this well-known issue for this kind of PV device.
GCL SI presents 480 W solar modules for offshore projects
GCL System Integration (GCL SI) introduced its NT10/60GT floating solar module at the recent SNEC 2025 trade show in Shanghai. It developed the seawater-resistant solution in collaboration with Norway’s Ocean Sun.
H3 Dynamics, XSun partner on solar, hydrogen, electric unmanned aerial systems
France-based Xsun and H3 Dynamics announced a collaboration to develop a solar, hydrogen and battery powered autonomous aerial system with integrated power management and able to navigate at low altitudes.
Improving LECO-compatible silver pastes to ensure TOPCon reliabilty
Researchers in China have created new silver pastes for TOPCon solar cell LECO manufacturing. The new pastes integrate either aluminum, gallium or iron and can reportedly keep cells’ electrodes securely anchored to the silicon cell surface due to the enhanced stability of the lead oxide (PbO) component in the glass powder.
GoodWe releases 112 kWh storage system for C&I solar
GoodWe has launched a 112 kWh battery storage system for commercial and industrial (C&I) solar projects, featuring 96% round-trip efficiency and a 6,000-cycle lifespan. The system allows parallel connection for up to 450 kWh of total capacity.
Lennox launches residential heat pump with space-saving design
The US-based company said its new EL18KSLV Side Discharge Heat Pump uses R-454B as the refrigerant and has a size ranging from 2 tons to 5 tons.
Indian researchers develop fast-charging sodium-ion battery, promising over 3,000 cycles
NAtrium Super Ionic CONductor (NASICON) materials continue to show their potential for sodium-ion anodes in high-performance batteries, with fresh research out of India delving more into the materials.
China’s Sunrev Solar to build 2 GW solar cell, module factory in Egypt
Sunrev Solar is building two integrated factories in Egypt with 2 GW of capacity each for solar cells and modules. The second phase will localize production of raw materials including silicon ingots and wafers.
First attempt to design solar power transmission demonstrator
Scientists in China have outlined a mission proposal for the China Academy of Space Technology space solar power (SSP) development program. It includes three solar arrays, microwave power transmission, and laser power transmission. The roadmap predicts this demonstration mission cound be attempted before 2030.
Offshore floating PV enduring world’s largest artificial waves
Offshore PV technologies were tested for the first time under the severe wave loads generated by Delta Flume, a 300 m long man-made flume with a wave generator that is capable of producing waves as tall as five meters. The testing is intended to standardize testing and certification processes for offshore floating PV systems.
