Laser optimization for half-cut solar cells
Scientists in Korea examined the parameters of laser ‘scribe and break’ processes used to cut silicon cells, in search of optimizations to reduce damage caused at the cut edges. They also found that varying encapsulant thickness or even adding a supportive rail across the back of a module can help reduce performance loss caused by cell cutting damage.
LG launches residential hybrid inverters for European market
South Korea’s LG Energy Solution says its new hybrid inverters are suitable for high-voltage and low-voltage configurations.
SDN unveils 600 W solar modules for floating PV
