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.-made perovskite-silicon tandem solar modules could be produced at around $0.35/W
Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.
Field testing shows perovskite solar modules can retain 78% of their initial efficiency after one year
Researchers from Belgium and the University of Cyprus have completed outdoor stability tests of perovskite solar mini-modules providing two-years of data on stability performance. The tests showed that the modules’ performance loss rates during the burn-in period of perovskites ranged between 7% and 8% per month.
JinkoSolar claims 33.84% efficiency for perovskite-silicon tandem solar cell
The result was confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences (CAS).
Waaree Energies, IIT Bombay collaborate to drive perovskite solar R&D
Waaree Energies will support creation of an advanced fabrication and characterization setup for high-efficiency perovskite solar cells at IIT Bombay.
Perovskite solar cell achieves higher stability with new tin oxide layer
Using atomic layer deposition, a research team from the City University of Hong Kong has created an an oxygen-deficient tin oxide layer to replace the more common fullerene electron transport layer in perovskite solar cells. The result is a 25%-efficient device that is able to retain around 95% of its efficiency after 2,000 h.
IIT Roorkee researchers develop silicon-perovskite tandem solar cells with power conversion efficiency of 28%
A research group at the Indian Institute of Technology Roorkee has fabricated 4-terminal silicon-perovskite tandem solar cells with power conversion efficiency of 28%. The team is now scaling up this technology to match 18.2 cm x 18.2 cm, commercial M10 solar cells dimension.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 28.8% efficiency
Conceived by Chinese scientists, the cell was built with new surface reconstruction strategy based on the use of 1,4-butanediamine (BDA) and ethylenediammonium diiodide (EDAI2) as surface modifiers. The device was able to retain 79.7% of its initial efficiency after 550 h.
Oxford PV unveils 26.9% perovskite tandem module efficiency record
Oxford PV has announced a record-setting 26.9% efficiency for its perovskite tandem module at Intersolar Europe 2024, the continent’s largest solar and energy storage event.
Indian scientists design lead-free perovskite solar cell with 23.61% efficiency
Developed through bandgap engineering and material design, the proposed PV device relies on a tin-based perovskite material known as CsSnI3-xBrx. It can reportedly be further designed to achieve power conversion efficiencies exceeding 24%.
