ABSTRACT
Recently, most scientists pay significant attention to nano-/micro-technologies of
solar cells. The light trapping technologies are used to reduce the reflection of
incident light, to scatter the incident light by rough surface, and to increase the
absorption of solar cells. The light trapping technologies have the main applications
for thin-film silicon solar cells, including using rough surfaces, single dielectric layer
interference, design of multilayers, nanowires, and so on.
In chapter two, we will introduce how the power of thin-film solar cell generate
and the theories of light trapping structure in detail. These include the diffraction
theories, the diffraction of sunlight on the surface, and the diffraction efficiencies.
Afterward, we use genetic algorithm to find the optimal light trapping structure with
two methods of simulation. We will also introduce the theories and applications of
genetic algorithm, and how the optimal simulation process works.
In chapter three, we will introduce the simulation software, TCAD, which is
often used to compute the optical and electrical properties of solar cell. In this work,
we only introduce the simulation of the optical properties. We set up an optimization
process that we can find the optimal light trapping structure by TCAD. As long as we
set the parameters and structures of solar cell, the optimal simulation process can help
us find the optimal light trapping structure. In the optimization processes, that genetic
algorithm calculates the solar cell absorbance continuously, and the structure is
adjusted every time. By repeating this process, we will find the optimal light trapping
structure.In chapter four, we use another method, RCWA( Rigorous coupled-wave
analysis ), to calculate the reflection and absorption of the sunlight incident of solar
cell, but the main purpose is still that we want to find the optimal light trapping
structure. We use the method that is like the one we used in chapter three to find the
optimal light trapping structure, through continuous simulations and calculations.
In final chapter, we discuss and summarize the two optimization methods, and
then we propose the future prospective of this work.
