LRESE-spinoff SoHHytec SA is working with a Swiss-based metal production facility to build a demonstration plant at the multi-100-kilowatt scale that will produce hydrogen for “metal annealing processes.Here we present the successful scaling of a thermally integrated photoelectrochemical device—utilizing concentrated solar irradiation—to a kW-scale pilot plant capable of co-generation of hydrogen and heat.

photoelectrochemical or integrated photovoltaic and electrolysis devices have demonstrated outstanding performance at the lab scaleThis heat treatment process is used to increase the flexibility of a material and reduce its hardness.was funded by the Australian Centre for Advanced Photovoltaics and is supported by the Australian Government.

annealing is done in a furnace with a high temperature ranging between 1652 and 2012 °F (900 and 1100 °C).as the solar panels which began to be installed in vast numbers about 20-30 years ago are reaching the end of their life and being decommissioned.

a team has shown that heating silicon solar cells using microwave radiation is nearly as efficient as using a furnace.

We find that silicon solar cells are heated rapidly in a microwave field and that effective B–O defect passivation can be achieved by microwave processing in less than 2 s.Unless a still unproven reproductive technology in rhinos -- in vitro fertilization (IVF) -- is used to sustain the subspecies.
