In a weblog publish entitled “Changing the rules: UNSW breakthrough opens door to silicon cells beyond 30% efficiency with singlet fission,” the Australian Middle for Superior Photovoltaics mentioned, “A team from UNSW Sydney has published a major advance that could unlock a new generation of high efficiency silicon solar cells — using singlet fission. The researchers demonstrate, for the first time, that a new class of stable organic molecules can be integrated with silicon to boost efficiency, while reducing heat and extending panel lifetime.”
It explains that the majority photo voltaic cells at this time convert one absorbed photon right into a single electron/gap pair, however singlet fission permits one excessive power photon to generate two excited electron/gap pairs, which has the impact of doubling {the electrical} yield from the bluest a part of the photo voltaic spectrum. “Theoretical models suggest that adding a singlet fission layer could improve silicon solar cell efficiency by more than 10 percent,” the Middle claims.
The researchers mentioned of their printed report, “Vital steps have been made within the improvement of singlet fission silicon photovoltaics, however all examples reported up to now use tetracene because the singlet fission materials. Tetracene is photochemically unstable and subsequently unsuitable for industrial purposes.
“Here we demonstrate singlet…
