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.
Longi, Pertamina plan 1.4 GW solar cell, module factory in Indonesia
Chinese solar manufacturer Longi and Indonesian state-owned energy company Pertamina are planning to build a 1.4 GW solar cell and module production facility in West Java, Indonesia.
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.
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.
New model for predicting residential PV fleet yield
To predict the energy yield of residential solar PV fleets based on limited information, Dutch researchers developed a probability-based mathematical model that provides rapid sky view factor (SVF) calculations, protects PV plant owner privacy, and was shown to be effective for studying PV potential in urban areas.
Chinese PV Industry Brief: More snapshots from SNEC 2025
Solar manufacturers announced a range of module sales agreements, supply deals and new products last week at SNEC 2025 PV Expo in Shanghai.
US panel price spread widens between India and Indonesia/Laos origin
In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports that US-assembled modules with imported cells continue to be heard between $0.26/W and $0.33/W, while modules with domestic content – which are still limited to just a handful of producers – are generally quoted between $0.4/W and $0.5/W.
Spanish researchers claim nest boxes in PV plants often misused for greenwashing
Researchers in Spain have warned that nest-box installations at PV plants are often poorly planned or used for greenwashing, with boxes placed in unsuitable locations, installed incorrectly, or lacking post-installation monitoring.
New accelerated aging test for perovskite solar cells
To assess ion migration-induced degradation modes via accelerated ageing of perovskite solar cells, an international research team investiagted using electric forward bias and dark storage approach.
