Plasmonic Thin Film Solar Cells
Thin film solar cell technology represents an alternative way to effectively solve the world’s increasing energy shortage problem. Light trapping is of critical importance. Surface plasmons (SPs), including both localized surface plasmons (LSPs) excited in the metallic nanoparticles and surface plasmon polaritons (SPPs) propagating at the metal/semiconductor interfaces, have been so far extensively investigated with great interests in designing thin film solar cells. In this chapter, plasmonic structures to improve the performance of thin film solar cell are reviewed according to their positions of the nanostructures, which can be divided into at least three ways: directly on top of thin film solar cell, embedded at the bottom or middle of the optical absorber layer, and hybrid of metallic nanostructures with nanowire of optical absorber layer

Amplification of rotation velocity using weak measurements in Sagnac's interferometer
We study the amplification of rotation velocity with the Sagnac
interferometer based on the concept of weak-value amplification. By using a
different scheme to perform the Sagnac interferometer with the probe in
momentum space, we have demonstrated the new weak measure protocol to detect
the small rotation velocity by amplifying the phase shift of the Sagnac effect.
At the given the maximum incident intensity of the initial spectrum, the
detection limit of the intensity of the spectrometer and the accuracy of
angular velocity measurement, we can theoretical give the appropriate
potselection and the minimum of optical path area before experiment. In
addition, we put forward a new optical design to increase the optical path area
and decrease the size of the interferometer to overcome the limit of instrument
size. Finally, our modified Sagnac's interferometer based on weak measurement
is innovative and efficient probing the small rotation velocity signal.Comment: arXiv admin note: text overlap with arXiv:1203.0827 by other author
