"device lifetime" is a correct and commonly used phrase in written English.
It refers to the length of time that a device is expected to function or remain usable. Example: "The new smartphone boasts a longer device lifetime than its predecessors, with a battery that lasts up to 12 hours."
This shall ensure a device lifetime of at least 10,000 operating hours.
The device lifetime was only 20 h when using Cs2CO3 as the EIL.
In addition, the gel phase is found to increase device lifetime by limiting solvent evaporation.
However, stressed operation will result in poor performance and limited device lifetime.
These findings highlight the importance of continued development of encapsulation architectures to further prolong device lifetime.
Irradiation tests to high electron doses have also been performed in order to estimate device lifetime.
Extended device lifetimes studies showed that the gels increase stability of the DSSCs by reducing the rate of solvent evaporation.
Device lifetimes and times to wearout are less important compared to the experience of an early or infant failure in the warranty period.
The focus of this review lies especially on the effect of chemical synthesis on the transport properties of the organic semiconductor and the device lifetimes.
Critical challenges that will need to be overcome include improving the sourcing and collection of CO2, increasing the efficiency of solar-assisted catalytic conversion of CO2 and H2O into fuels, extending device lifetimes, reducing costs, and investing in infrastructure upgrades to reduce the large gap between current laboratory demonstrations and deployable technology.
The scaled initial concentrations in the layers, beginning with the layer farthest from the environment are 1.6, 0.4, and 0. Desired average delivery rates and device lifetimes are achieved by a single, typically empirical step in which the diffusivity is fixed to give an optimized utilization of the chemical over the life of the device.
