Fiber-Based photovoltaic cells are solar collectors that utilize internal reflectors to confine light into an
organic absorber, thereby significantly enhancing absorption cross-sections of the device. The performance
of the device is particularly sensitive to internal resistivity of the "optical can." Using ITO of differing
thicknesses we show that can be controlled and that Jsc's that exceed planar device limits can be achieved.
However, the morphology and film quality of the layers must be maintained to achieve maximum
performance.
The microfluidic fluorescence detecting system which is used to measure the concentration of Ca2+ had been designed.
On the microfluidic chip we designed, cell-dyeing, cell fostering, reagent injecting and other operations can be
completed. The monochromatic light came from optical monochromator which can emit continuous spectrum was used
to excitated the fluorescent probe in the cell, then the fluorescence signal and image were sampled by the PMT and CCD,
at last the data was processed and the content of Ca2+ in the cell was figured out by using the fluorescence ratio method.
Meanwhile, by using the system, the dynamic curve of [Ca2+]1 in cell was given after being stimulated by high K+. The
precise result verifies that the system is stable and credible and it meets the requirement of detecting [Ca2+]i in live cells
in the filed of physiology.
