Abstract ▼ AI-Helper

This paper presents a Technology-CAD (TCAD) simulation of the characteristics of crystalline Si pillar array solar cells. The junction depth and the surface concentration of the solar cells were optimized to obtain the targeted sheet resistance of the emitter region. The diffusion model was determined by calibrating the emitter doping profile of the microscale silicon pillars. The dimension parameters determining the pillar shape, such as width, height, and spacing were varied within a simulation window from ${\sim}2{\mu}m$ to $5{\mu}m$. The simulation showed that increasing pillar width (or diameter) and spacing resulted in the decrease of current density due to surface area loss, light trapping loss, and high reflectance. Although increasing pillar height might improve the chances of light trapping, the recombination loss due to the increase in the carrier's transfer length canceled out the positive effect to the photo-generation component of the current. The silicon pillars were experimentally formed by photoresist patterning and electroless etching. The laboratory results of a fabricated Si pillar solar cell showed the efficiency and the fill factor to be close to the simulation results.

제안 방법

TCAD simulation study is needed to understand the inherent physical, and geometry dependent device properties of wire array solar cells, and to optimize light absorption and carrier collection efficiency [8]. In this paper, the simulation studies based on process and device simulation, of the effect on the dimensions determining the pillar shape, such as width (or diameter), height, and spacing are presented. A proper, calibrated two-dimensional diffusion model is discussed to study the effect of emitter junction depth and surface doping concentration of the pillars.

이론/모형

TCAD simulation was performed using a Silvaco process and device simulator which calculates optical generation rate with a ray tracing model and solves Poisson’s and continuity equations.
