First attempt to fabricate solar cells based on antimony selenoiodide
South Korean scientists have produced a solar cell based on antimony selenoiodide, with a 4.1% efficiency, a short-circuit current density of 14.8 mA cm2, an open-circuit voltage of 473.0 mV, and a fill factor of 58.7%. They claim the cell exhibits excellent stability in humid conditions.
A 15.2%-efficient solar cell that you can fold in half
Scientists in South Korea developed a foldable thin-film device with some promising characteristics. Integrating a perovskite cell material and a carbon nanotube electrode, the group fabricated a device that achieved 15.2% efficiency and could withstand being folded more than 10,000 times at a bending radius of 0.5mm.
Solliance, MiaSolé hit 26.5% efficiency on tandem CIGS/perovskite solar cell
MiaSolé and Solliance have achieved record performance by optimizing the bandgap and the efficiency of both the rigid semi-transparent perovskite top cell and the flexible CIGS bottom cell.
India joins race to develop high-efficiency solar cells
India’s Ministry of New and Renewable Energy is funding research to develop high-efficiency crystalline silicon solar cells, as well as perovskites.
Silver prices expected to rise by 11% this year
Silver demand for PV production worldwide is forecast to grow to 105 million ounces this year, as overall demand hits an eight-year high. Prices for the precious metal could reach a seven-year high of $30.00 per ounce this year but, according to the Silver Institute, this level is still far away from any critical threshold that would make silver supply for the solar industry problematic.
Modeling the potential of lead-free perovskites
Scientists in India modeled the performance of tin-based perovskite (methylammonium tin triiodide) finding that with careful optimizations the material could achieve efficiencies beyond 28%.
Indian manufacturer to open 750 MW solar fab by April
Solar manufacturer Premier Energies is setting up a factory in Telangana with an annual cell and module production capacity of 750 MW. The fab will be equipped to produce large-format panels with wafer sizes up to 210mm.
Large-size solar tile from Spain
The product is available both with monocrystalline and CIGS solar cells and is claimed to be the world’s largest solar tile with dimensions of 457 x 510 mm.
Effective approaches to build colored perovskite solar cells
Scientists in Singapore have conducted a review of all existing methods to produce colorful opaque and semitransparent perovskite solar cells for applications in BIPV and urban environments. They identified two general approaches consisting of coloring the perovskites via external or internal modifications.
Hybrid tandem perovskite solar cell with 18.04% efficiency
South Korean researchers claim to have developed a PV cell with a higher efficiency rate than any other tandem cell based on perovskite and organic materials.
