Researchers from UNSW have found an affordable sulfur-based additive that may enhance the sturdiness of perovskite photo voltaic cells with out compromising effectivity. The 1-DDT (Dodecanethiol) additive has “multifunction” – one thing that stunned the UNSW Faculty of Photovoltaic and Renewable Power Engineering group. In addition to strengthening the lithium used within the cavity of the transport layer of the perovskite cells to attain excessive effectivity, the additive additionally induces oxidation and prevents water ingress – each options that add of energy.
“This 1-DDT locks the lithium in that layer, and I believe that is an enormous contribution and an necessary mechanism to make it secure,” Professor Xiaojing Hao mentioned. Australia’s pv journal.
Perovskite cells made with this novel additive have been in a position to preserve greater than 90% of the preliminary effectivity after working at most energy level beneath a photo voltaic illumination for 1,000 hours, and greater than 93% of the preliminary effectivity after remaining in open circuit situation beneath one. daylight for two,000 hours. This reported health result’s one of the best in Australia and among the many highest on this planet.
The outcomes of the analysis have now been printed within the Nature Photonics and co-authored by Professor Martin Inexperienced, often called the “father” of contemporary photo voltaic cells.
Whereas perovskite’s excessive effectivity has been confirmed, “everybody has issues about long-term stability,” Hao mentioned..
