TCO-free heterojunction silicon solar cell with 22% efficiency
The cell was built with a phosphorus-doped n-type Czochralski (Cz) silicon wafer with a resistivity of 1.09Ωcm and a thickness of 170mm. Ti/Au/Ag metal stacks were used for the contact with the hydrogenated amorphous silicon (a-Si:H) layers.

The panel in white
Slovenian solar module manufacturer Bisol has developed a white panel with a power output of 190 W. The product is claimed to be an ideal solution for seamlessly blending with large surface buildings and maintaining their historic character.
Germany may install 150,000 residential batteries this year
German market research company EUDP Research expects 85% of the new storage systems will be used in new PV systems and 15% in existing installations.
Spain may host 2 GWh of liquid air storage
Highview Power plans to develop up to seven projects with a capacity of 50 MW / 300 MWh each in Asturias, Cantabria, Castilla y León and the Canary Islands thanks to an estimated investment of $1 billion.
Optimization model to combine residential PV with hybrid hydrogen storage
German scientists have outlined a model to combine hydrogen storage with conventional battery storage in high-efficient energy buildings powered uniquely by photovoltaics. In the proposed configuration, the DC power of the PV system is connected directly to the hybrid hydrogen system, a lithium-ion battery, an electric water heater, and an inverter, which in turn would provide AC current to the household and a heat pump.
