| Outline of Final Research Achievements |
We proposed a new isogeometric boundary element method for 2D singly periodic boundary value problems of 2D Helmholtz equation and developed a shape optimisation system based on the boundary element method, adjoint variable method, and quasi-Newton method. The system is capable to design high-efficient thin Silicon solar cells. In an optimisation problem to maximise the relative energy absorption rate in the silicon layer of a four-layer (air/Si/Ag/air) model, we could obtain the optimal shape that can absorb 67% of the incident energy. The present result together with the computer program posted on the Internet is significant to design plasmonic devices. Meanwhile, we obtained some results for 3D problems, which can be exploited for the succeeding research starting from FY2018.
