VSun Solar signs polysilicon supply deal with OCI
OCI has agreed to supply polysilicon to Toyo Solar, the cell production subsidiary of VSun Solar, in order to support wafer production.
Fully printable flexible perovskite solar cell achieves 17.6% efficiency
Developed by scientists in Canada, the 0.049 cm2 solar cell was built in ambient air fabricationand with a reactant known as phenyltrimethylammonium chloride (PTACl). It achieved an open-circuit voltage of 0.95 V, a short-circuit current density of 23 mA cm−2, and a fill factor of 80%.
Enhancing PV performance with graphite-based thermoelectric generator
Indian scientists have built a PV system coupled with a thermoelectric generator using graphite as a heat dissipator. The graphite-based system achieved a higher output and temperature gradient than a reference system without heat dissipation.
Weekend Read: Energy sovereignty
Native American lands boast serious PV potential in the United States but getting projects off the ground hasn‘t always been easy. Different tribes are willing to take power generation into their own hands and the landscape could be shifting, thanks to funding from the US Inflation Reduction Act (IRA) and other programs.
Premier Energies unveils 590 W TOPCon bifacial PV modules
Premier Energies says its n-type TOPCon bifacial glass-backsheet modules are available in power outputs of 555 W to 590 W, with an efficiency rating of up to 22.83%.
Meyer Burger prepares to shut down plant in Germany
Swiss solar panel maker Meyer Burger will seek shareholder approval for a rights issue of as much as CHF 250 million ($284 million) to finance the completion of its US manufacturing facilities in Colorado and Arizona.
Navitas Solar introduces n-type TOPCon bifacial modules
Navitas Solar, an Indian solar panel manufacturer, has developed new n-type TOPCon bifacial modules with power outputs ranging from 560 W to 630 W.
Inverted perovskite solar cell with 2D/3D heterojunctions achieves 25.6% efficiency
An international research team claims to have achieved optimal passivation in inverted perovskite solar cells by applying thin layers of low-dimensional perovskite on top of a 3D perovskite film. The resulting cell achieved an open-circuit voltage of 1.19 V, a short-circuit current density of 24.94 mA cm2, and a fill factor of 85.9%.
New research analyzes performance ratios of bifacial PV
A comparison between monofacial and bifacial PV systems in Ghana showed how changes in system parameters can affect the bifacial gains. The researchers found that changing the albedo of a land-based system can increase the bifacial gain from 5.25% to 14.5%.
Researchers develop hemispherical organic solar cells
A Turkish research team has tested a hemispherical shell-shaped organic active layer for photovoltaic applications. The group found the shape maximizes light absorption and angular coverage when compared to flat-structured cells, suggesting the structure would be beneficial for applications requiring flexible light capture such as wearable electronics.
