organic solar cells

A team of researchers in Germany has fabricated a non-fullerene acceptor-based organic photovoltaic cell featuring a bilayer solution-processed hole transporting layer. It recorded a power conversion efficiency of 17.1% and maintained 93% of its initial efficiency after 1,800 hours under continuous solar cell operation at 60 C.

A research team from two Chinese universities claims to have fabricated an organic solar cell with the highest power per weight ratio to date. The device has a thickness of less than 1.5 micrometers.

German organic PV manufacturer Heliatek has announced a new series of lightweight modules. The Heliasol 436-2000-CFE-45-600V panels are IEC 61215 and IEC 61730 certified and have a 20-year lifetime warranty.

An international research team developed an organic solar cell based on a novel non-monotonic intermediated state manipulation strategy. The device reportedly showed non-radiative recombination losses while exhibiting remarkable power conversion efficiency.

Researchers from Japan’s Riken Center for Emergent Matter Science have fabricated an organic solar cell that has achieved waterproofness without reducing flexibility. At 3 micrometers thick, it is thought to be the first cell of its kind to survive a washing machine cycle and retain efficiency after multiple cycles.

Researchers in China have designed an organic solar cell the uses an acceptor based on selenium as an alternative to commonly utilized non-fullerene acceptors. The new acceptor enabled the cell to have reduced non-radiative recombination loss and improved dielectric constant.

Ribes Tech, a spinoff of the Italian Institute of Technology, has established a roll-to-roll process to produce organic photovoltaic modules that it says can be expanded to enable volume production of PV modules for indoor sensors, trackers, and electronic devices.

Germany’s Fraunhofer ISE has achieved a world record efficiency for organic cells at the lab level. It now aims to bring the PV technology to market maturity.

Hong Kong Polytechnic University researchers have developed a binary organic solar cell (OSC) with a record power conversion efficiency of 19.31%. They invented a non-monotonic intermediate state manipulation strategy to lower the non-radiative recombination loss and boost efficiency.

Dutch scientists have used atomic layer deposition to build an organic solar cell with a tin oxide electron transport layer. This improved electron mobility and transparency, resulting in a record fill factor.
