Hanwha Q Cells, Helmholtz-Zentrum Berlin claim 28.7% efficiency for 2T perovskite-silicon tandem solar cell
The Korean manufacturer and the German research center were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.
Terahertz, microwave spectroscopy for more accurate PC cell assessments
A German research group has used spectroscopic methods based on terahertz or microwave radiation and has discovered that they might help with more precise assessments of the characteristics and performance of solar cells. Their proposed approach purportedly enables the evaluation of maximum possible efficiency levels for emerging materials such as perovskites in solar cells.
Macquarie-led consortium acquires Reden Solar
French solar developer Reden Solar was on sale since October. The €2.5 billion transaction is expected to be finalized in the third quarter of this year.
Debate on land allocation for ground mounted solar heats up in Israel
Conflicts are arising within the Israeli government on how much land should be further allocated for ground mounted PV installations. According to the local renewable energy sector, more land is needed, inevitably, if the country’s renewable energy targets must be met.
Spectrum splitters to raise efficiency of perovskite-silicon tandem solar cells
Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may be of up to 6%. The proposed cell configuration was also found to be economically competitive.
Hybridizing PV, redox flow batteries and geothermal heat pumps
A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.
Autonomous laser system clears birds from PV arrays
Bird Control Group’s autonomous laser system reduces bird populations in specific areas by more than 70%. In many cases, bird activity has been reduced by more than 99%.
Mitrex releases solar brick for BIPV facades
Mitrex solar facades are being installed on a 7000 square feet area on a building in Canada, producing an estimated 90,000 kWh of power annually.
Chinese PV Industry Brief: More glass capacity and a 5GW module factory under construction
Glass maker Flat Glass wants to add 7,200 MT of new glass capacity spread across six new production lines and panel manufacturer Eging PV started construction of a new PV panel factory with an annual capacity of 5 GW.
Thermochemical storage-plus-rooftop PV to store heat for winter months
A group of researchers in the United Kingdom is developing a modular, multi-vector energy system that can be installed into new homes and retrofitted into existing buildings to provide seasonal heat storage. In the proposed system configuration, a rooftop solar array would be used to power a heat pump or another electrical heating element, which in turn produces the heat to be stored by thermal devices.
