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.
Aleo Solar announces 400 W module
The German manufacturer will offer the solar module for rooftop PV applications from the third quarter of 2021. Aleo Solar will install a new production line at its factory for the new product.
Nexwafe raises €10 million for commercialization of wafer tech
Wafer manufacturer Nexwafe is currently trying to commercialize its highly efficient monocrystalline wafer technology.
Performance improvements for anomalous photovoltaic effect
A German research team has created a new solar cell architecture with self-assembled, three-dimensional nanocomposite thin film. The special cell configuration purportedly improves electrical output by a factor of five.
Chinese PV Industry Brief: More wafer and polysilicon capacity and new suppy deals
Wuxi Autowell has begun construction on its 50 GW wafer factory in Guangdong province and Longi and Wuxi Shangji Automation have announced new supply deals. GCL-Poly has announced it will raise the production capacity of its factory in Jiangsu from 6,000 to 10,000 metric tons – despite the company suffering a cross-default at the weekend.
Dual passivation tech for 20.14%-efficient perovskite solar cell
Europium ions have been used by Chinese researchers to passivate both the perovskite and electron transport layer (ETL) films of a MAPbI3 perovskite solar cell. As a result, the device’s efficiency was raised by approximately 1.5%. The dual passivation approach also achieved an increase in the cell’s fill factor and open-circuit voltage.
