New process could yield 26.6% efficient IBC cells
Researchers in Germany are trialing a host of new processes and materials to develop interdigitated back contact solar cells. A deposition technology named ‘hot-wire’ chemical vapor deposition, is said to provide excellent passivation without the need for treatments such as recrystallization or hydrogenation.
A new front electrode structure for shingled PV panels
Researchers in Korea have proposed a new design for dividing and bonding which is said to provide higher efficiency from fewer fingers. The number of fingers optimized for division into five cells was 128 and for three, 171. Five offer power conversion efficiency of 17.346% and three 16.855%.
A new strategy to mitigate voltage spikes in small solar systems
The approach combines virtual impedance and a modified pulse-width modulation strategy to suppress fault currents in grid-connected PV systems.
The best way to predict the I-V profile of PV panels
A study has considered the best mathematical models for predicting solar module performance under varying conditions.
Panasonic claims 16.09% efficiency for lightweight perovskite solar module
The device has an area of 802cm² and thickness of 2mm. The manufacturer claims it improved module performance through an inkjet coating method and a reduction in weight by using thin glass substrates.
Mysterious new chlorophyll with potential PV applications
Japanese researchers are studying the ‘Chl f’ substance which features a pigment in photosynthesis which can absorb far-red light from the lower end of the spectrum.
When losing a few PV panels can cost millions of dollars
European satellite operator Eutelsat has revealed one of the two solar arrays on its recently launched 5 West B satellite has been lost. Only 45% of the craft’s generation capacity can be operated, hitting the company’s bottom line to the tune of $5-10 million.
A clean energy world would support millions of new jobs
A study from Finland’s Lappeenranta University of Technology has predicted solar and other renewables can provide a global energy jobs revolution – just as four European operations revealed recent struggles.
All-inorganic perovskite solar cell hits 16.1% efficiency
Researchers from the City University of Hong Kong have developed an all-inorganic perovskite cell with an electron-pair donor which offers a pair of non-bonding electrons. The cell was developed by applying that ‘Lewis base’ small molecule to passivate the inorganic perovskite film.
Jinko claims two more efficiency records for bifacial panels
The Chinese manufacturer has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively. The results were confirmed by Germany’s TÜV Rheinland.
