Different testing in additional intense situations has discovered much less optimistic outcomes, with one tutorial examine discovering that perovskite cells in sizzling and humid Saudi Arabia misplaced 20% of their effectivity after one 12 months of operation.
These outcomes are for one 12 months of testing. How can we inform what is going to occur in 30 years?
Since we don’t have years to check each new materials that scientists dream up, researchers usually put them via particularly punishing situations within the lab, bumping up the temperature and shining brilliant lights onto panels to see how rapidly they’ll degrade.
This type of testing is customary for silicon photo voltaic panels, which make up over 90% of the industrial photo voltaic market at present. However researchers are nonetheless figuring out simply how effectively the correlations with recognized checks will switch to new supplies like perovskites.
One of many points has been that gentle, moisture, and warmth all contribute to the short degradation of perovskites. Nevertheless it hasn’t been clear precisely which issue, or mixture of them, could be finest to use within the lab to measure how a photo voltaic panel would fare in the true world.
One examine, revealed final 12 months in Nature, steered {that a} mixture of excessive temperature and illumination could be the important thing to accelerated checks that reliably predict real-world efficiency. The researchers discovered that high-temperature checks lasting just some hundred hours (a few weeks) translated effectively to almost six months of efficiency in out of doors testing.
Corporations say they’re bringing new photo voltaic supplies to the market as quickly as this 12 months. Quickly we’ll begin to actually see simply how effectively these checks predict new applied sciences’ means to face up to the powerful job a industrial photo voltaic panel must do. I do know I’ll be watching.
