It is common knowledge that the slow photocurrent response time of dye-sensitized solar cells (DSSCs) is due to trap-limited diffusion of photogenerated carriers in the mesoporous photoanode; therefore this quantity should depend on the carrier generation profile and on the carrier density, which ...
We have applied the method to simulated spectral responses as well as spectral responses measured from real solar cells. 展开 会议名称: Photovoltaic Specialists Conference, 1996: Conference Record of the Twenty Fifth IEEE Photovoltaic Specialists Conference, 1996, 1996 ...
With our approach, we are able to distinguish the influence of different physical effects as they become dominant at different current densities or at different time regimes. This enables us to estimate the electron and hole mobilities separately by fitting the experimental results. Furthermore, ...
(c) The decay dynamics of the 1G4 level in Gd2O2S:Tm31 (x%) with x 5 0.1 (black), 1 (red), 5 (yellow), and 10 (blue), excited at 465 nm and detected for the 1G4 R 3F4 emission at 653 nm. Solid lines are fits to Equation (2), yielding an intrinsic lifetime of t0 ...
or four infrared photons of∼1800 nm, respectively. The cross-relaxation steps between Tm3+ions that lead to quantum cutting are identified from (time-resolved) PL as a function of the Tm3+concentration in the crystal. A model is presented that reproduces the way in which the Tm3+concentrat...
As a result, short-wavelength IR photodetectors operating at 1,550 nm with a record external quantum efficiency, reasonable detectivity, and fast response time are demonstrated. Summary Fast and sensitive infrared (IR) photodetection is of interest for depth imaging that is fundamental to machine ...

With the current density increasing, the fuel cells voltage dropped, response time of the membrane humidity was 50 s. About 150–200 s after the voltage drop came the flooding. They found a certain fuel cell, with the design parameters fixed, the dynamic response was affected by many ...
