Longi claims 82.15% bifaciality record for its PERC solar cell
After announcing a record 22.71% conversion efficiency with its monocrystalline passivated emitter rear contact (PERC) solar cells in October, the Chinese solar manufacturer now claims it has achieved an 82.15% record bifaciality for the bifacial version of the same cell.
Italian researchers use graphene oxide to increase efficiency of perovskite cells
Scientists of the University of Florence claim that graphene-based electron transport layers (ETL) achieve higher carrier injection with respect to most commonly used ETLs.
Cambridge scientists say perovskite-based PV cells can achieve maximum 30% efficiency
Researchers from the University of Cambridge and Italy’s Politecnico di Milano have set a time limit for ultrafast perovskite solar cells and have quantified the speeds at which future solar cells would have to operate in order to increase efficiency.
US scientists use nanoscale structures to lower reflectivity in solar cells
The researchers used micro- and nanometer length structures to develop anti-reflective coatings to reduce reflectivity in optical devices such as solar cells, glasses and cameras.
Bluecell halts solar cell production in Germany
Three years after acquiring the cell production business of insolvent Sunways, Bluecell has also given up. The 100 MW production equipment at the company’s facility in Arnstadt will be sold by the end of 2017.
GCL-SI achieves 20.1% efficiency for its PERC solar cells in mass production
The Chinese PV manufacturer has achieved a new efficiency breakthrough for its PERC solar cells, with the help of nanostructured black silicon. GCL-SI plans to reach an efficiency of up to 21.0% by the end of this year.
Atomic scale design could pave the way to more persistent solar cells, study says
Researchers from ICL claim to have discovered the cause for the rapid decrease in performance of perovskites. Adding iodide ions may help improve the stability of solar cells.
Japanese scientists seek to develop solar cell able to absorb spectral components of longer wavelengths
The new technology is designed to capture the spectral components of longer wavelengths that are usually lost during transmission through the solar cell. The Japanese scientists are using up-conversion of below-gap photons to reduce power losses and increase the cell efficiency.
Imec claims 22.8% efficiency for bifacial n-type PERT solar cell
The Belgian research institute has developed a bifacial n-PERT solar cell with a conversion efficiency of 22.8%. Imec researchers claim this cell has the potential for a cost-of-ownership at module level of less than $0.30/W.
