Photon-enhanched rechargeable batteries for solar storage

Japanese scientists have analyzed storage systems that combine PV and high-energy-density metal batteries. The rechargeable batteries have advantages such as low-charge voltage and high energy density, but stability and safety must be addressed before they reach commercial maturity.

UAE aluminum maker enters silicon metal, polysilicon business

Emirates Global Aluminium (EGA) wants to produce silicon metal to create an integrated supply chain for the PV industry in the United Arab Emirates.

Perovskite solar cells based on down-conversion materials

An international research group has assessed the potential of down-conversion materials to overcome the poor blue response of solar cells. They analyzed how such materials could be used to improve the performance of perovskite-based devices and found that certain advances might be achieved.


Novel floating PV system design from Norway

Norwegian scientists have tested a new floating PV system concept at a water reservoir in Sri Lanka. The system is made of composite beams to support the solar panels and high-density polyethylene (HDPE) pipes to provide buoyancy.
