Novel design of solar cell efficiency improvement using an embedded electron accelerator on-chip.
In this paper, we propose a novel design of an electron accelerator on-chip by using a small scale device known as a PANDA microring resonator, which can be embedded within the solar cell device, where the trapped electron can be accelerated and moved faster to the final destination. Therefore, the solar cell efficiency can be improved. In principle, a PANDA microring can generate the optical tweezers for hole tapping and transportation. The transported holes can be accelerated and moved via the optical waveguide to the solar cell device contact, where the effect of defects in silicon bulk can be solved. Therefore, this technique can be used to improve the solar cells performance. In practice, the accelerator unit can be embedded within the solar cell device, which allows the trapped holes moving to the required destination. This is claimed to be a novel technique by using a PANDA microring to accelerate the holes for solar cell performance improvement. Finally, this technique is the starting point of using a PANDA microring to enhance the performance of semiconductor device.
