organic PV

The mini-panel showed a short circuit current of 58.1 mA, an open circuit voltage of 3.63 V, and a fill factor of 58.26%. It has a power output is 122.9 mW and an active area of 14 cm2.

A British-German research team claims that organic PV technologies may become mature enough to compete with crystalline silicon and thin-film products not only in BIPV, but also in power generation in the electricity market. In order to get there, however, organic PV products will have to achieve higher efficiencies.

Over the last few months, Nastaran Meftahi has been spending her time in pandemic lockdown developing a machine-learning model to predict the future of next-generation organic solar cells.

The French organic PV specialist has achieved the record efficiency for cells exposed to low light (1000 lux). Armor sees potential in energy-intensive applications.

Researchers at the Indian Institute of Technology Kanpur have developed 12×12 cm2 sub-modules from organic solar PV cells on a paper substrate that could be used to power flexible electronic devices under an indoor lighting environment. The modules are said to deliver a power density of up to 12 µW/cm2 under illumination from a 1000-lux cool‐white LED.

Scientists in Germany have achieved 12.6% efficiency with a 26 sq cm organic panel and 11.7% for a 204 sq cm device. The feats were achieved with a new module layout and a slower, high-resolution, short-pulse laser structuring process.

Researchers in South Korea have used the process to increase performance and the replicability of large-area organic cells. The method was used during film formation to speed up solvent evaporation.

Researchers in Taiwan have developed an organic PV module with an active area of 216 sq cm. The panel is said to have open circuit voltage of 10.6 V and short circuit current of 1.82 mA. It also features the highest efficiency reported for a panel of its kind which has an active area of more than 100cm2

Scientists in China have developed an organic module with an area of 18 cm2 based on a non-fullerene acceptor called DTY6. The device has a certified efficiency of 13.98%, but when a non-halogen solvent was used, it even reached 16.1%.

Scientists at Saudia Arabia’s King Abdullah University of Science and Technology demonstrated an organic PV cell that can simply be printed onto a piece of paper. The cell set a new efficiency record for a fully inkjet-printed device, and its designers envisage applications in integrated medical sensors.
