Flexible PV panels based on hyperconnected back-contact solar cells
US start-up mPower Technology is scaling up its flexible crystalline silicon solar module technology for spatial and terrestrial applications. The back-contact solar panels consist of micro-singulated silicon dies that are “hyper-interconnected” in series or in parallel. The devices have efficiency ranging from 22 to 23% depending on the size or applications.
Novel IBC solar cell architecture based on crystal photonics shows efficiency potential of 29.1%
Scientists in Germany designed a poly-Si on oxide (POLO) interdigitated back-contact (IBC) solar cell integrating photon crystals and found this architecture has the potential to reach a power conversion efficiency of over 28%, which would be 1% higher than the current practical limit set by the scientific community. They also found that by improving passivation, the efficiency may be raised up to 29.1%.
New PV module recycling tech from France
French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.
Rooftop solar price to keep rising this year
British analyst GlobalData has predicted residential and commercial rooftop panels will not return to a declining price trend until next year, with post-Covid logistics headaches the cause, rather than a polysilicon shortage.
India and Australia sign letter of intent on solar, ‘clean’ hydrogen
India and Australia have signed a letter of intent to cooperate on scaling up the manufacture and deployment of ultra-low-cost solar and clean hydrogen.
Soluna unveils 1.28 kWh portable power generator
Soluna’s new generator can be combined in a two-unit system to reach a capacity of 2.5kWh. It features built-in 120V(AC) output, continuous AC output power of 1,200W, and peak output of up to 2,400W.
Solar power prices rising with demand
Recent BloombergNEF research shows that corporations procured a record 31GW of renewable energy in 2021, and LevelTen Energy says that growth occurred despite more than a year of price increases.
New poly fabs could head off first-half solar project slowdown
Norwegian analyst Rystad Energy has warned the solar industry could suffer the same effects of rising input prices as onshore wind developers grappling with ever more costly steel, with much hinging on how much solar panel raw material polysilicon can be manufactured.
Solar manufacturers request early allocation of INR 19,500 crore boost to PLI Scheme
All stakeholders are expecting the Indian Renewable Energy Development Agency Limited (IREDA) to expedite and issue letters of award to balance companies that have bid under the production-linked incentive (PLI) scheme for solar. Most players have already acquired land and some have even done the land development work and basic construction in anticipation of the award pending for the last three months.
‘Solar and wind deployment could not now be stopped if we wanted to’
BloombergNEF’s Jenny Chase has surveyed the state of affairs in world solar for clean energy journal Joule and said the technology’s historic ability to surmount obstacles – and persistently confound analysts’ predictions – should offer a reason for hope.
