Spanish start-up unveils 1kWh portable battery for multiple uses
The portable storage system contains lithium batteries, a charger, and an inverter, all fully integrated into a sealed and protective case.
Pacific Energy unveils hybrid power solution based on PV, electric turbo compounding
KPS Power Generation has converted a 10 MW diesel-fueled power station at a mine in South Australia into a hybrid PV facility.
New hybrid inverters for rooftop PV from Germany
The BW-HY3600 and BW-HY4600 inverters can be integrated with existing on-grid or off-grid PV systems and a battery storage system of 48V. Both devices, according to German manufacturer Bosswerk, have AC and DC coupling and are particularly suitable for residential and commercial solar arrays.
Quantum dot layer pushes perovskite solar cell efficiency up to 25.7%
Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm2, they achieved a record efficiency of 25.7% and high operational stability.
Perovskite-organic tandem PV cell with 23.6% efficiency via optimized interconnecting layer
Scientists in Singapore have developed a cell that could be used to power vehicles and boats, among other applications. The tandem device purportedly retains 90% initial efficiency after 500 hours of maximum power point tracking under continuous one sun illumination.
Zinc-air battery, CHP and PV to power apartment complex in New York
A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.
Czechia’s first floating photovoltaic plant
Operated by Czech utility CEZ Group, the pilot solar plant will be located at different heights during the charge and recharge cycles of a pumped-hydro plant and the difference in height may reach up to nine meters.
Effects of Swirl defects in solar cells based on Czochralski wafers
Scientists in China analyzed defective solar cells based on Czochralski (Cz) silicon wafers and found Swirl defects may be responsible for an efficiency drop of up to 4.7%. According to them, the presence of Swirl defects could be mitigated by applying a heat treatment at a temperature above 1,050 degrees Celsius in a clean environment before the manufacturing of the solar cells.
Shanghai Electric sounds death knell for CIGS manufacturing project backed by $197m of public money
With five public entities having committed RMB1.25 billion into a project to produce copper, indium, gallium, selenide solar modules five years ago, the joint venture has been abandoned at an estimated impairment cost of RMB1.42 billion.
Growatt releases battery for off-grid solar
Growatt’s new AXE LV battery covers a wide range of capacities, from 5kWh to 400kWh, and can support off-grid systems with power outputs of 3kW to 30kW.
