Abstract |
|
|
|
This paper presents a novel design of an electron accelerator on-chip that can be used to trap and control electron within a small scale device known as a PANDA microring resonator, in which the trapped electron can be accelerated and moved faster to the final destination and eventually, the solar cell efficiency can be improved. In principle, a PANDA microring can generate the optical tweezers for electron trapping and transporting. The transported electron hole can be accelerated and moved via the optical waveguide to metal contact, where the effect of defects in silicon bulk can be solved. As a consequence, this technique can improve the solar cells performance. In practice, the accelerator unit can be embedded within the solar cell device, which allows the electron trapping and transporting to the required destination. New results of this paper are important for solar cell works. This technique is novel by using a PANDA microring to accelerate the holes for solar cell performance improvement. Ultimately, this technique is the starting point of using a PANDA microring to enhance the performance of semiconductor device.
