Inverted perovskite solar cell based on self-assembled bilayer achieves 26.08% efficiency
The proposed bilayer is used as a hole contact material that ensures an improved adhesive contact with the perovskite film. It consists of a phosphonic acid self-assembled monolayer with an upper layer made of an organic compound known as triphenylamine.
The impact of wind-induced vibrations on solar modules
Researchers from the UAE and Singapore have assessed how wind-induced vibrations increase mechanical stress in PV panels and have found these vibrations could lead to microcracks, more serious mechanical failures, misalignments, and ultimately to the system collapse.
Researchers develop high transparency nanocellulose film for photovoltaics, packaging
The nanocellulose film can be used for light management as its light scattering is adjustable. It also exhibits a transmittance of over 80% at 550 nm.
Chinese startup unveils flexible perovskite photovoltaic modules with 15.6% efficiency
Mellow Energy claims its ML-Flex panel is currently the world’s largest flexible perovskite solar module. Available in five versions with power output ranging from 260 W to 300 W, the module measures 1,200 mm x 1,600 mm and weighs only 2.04 kg.
U.S. solar panel supply ‘sufficient’ but two bottlenecks hold industry back
Solar panel supply is no issue, but other installation bottlenecks have emerged, said a report from Clean Energy Associates.
Daytime radiative cooling tech for solar panels
A Chinese research group has created a new radiative cooling technology for photovoltaic devices. It consists of a chamber made of ethylene-tetrafluoroethylene and polydimethylsiloxane that, when placed above the solar cells, can reportedly achieve an average cooling power of approximately 40 W/m2.
How to achieve higher power yield in east-west oriented solar arrays deployed on flat roofs
Researchers in Switzerland investigated different setups to maximize energy yields per area for PV Systems on flat roofs. Their work revealed that using horizontal single-axis tracking and reflectors could add up to 5% greater performance.
Organic solar cells for space demonstrate radiation resistance, self-healing
Conventional silicon solar cells degrade rapidly in space, and gallium arsenide cells are heavy and inflexible. Research from the University of Michigan suggests carbon-based solar cells could be a good fit for space applications.
China reviewing anti-dumping duties on solar-grade silicon from US, South Korea
The Chinese government says it will review 2014 anti-dumping duties on US and South Korean polysilicon imports, and will maintain them during its investigation, which was requested by 13 Chinese manufacturers.
Chinese PV Industry Brief: Aiko Solar starts making back contact PV panels
Aiko Solar has started production at its Jinan factory, its third facility for n-type all-back-contact solar modules. The plant is designed for 30 GW of solar cell and panel capacity, with the first 10 GW phase set to reach full output by late 2025.
