Title
Fabrication and Characterization of Polycrystalline Silicon Solar Cell
김규수Kye Soo Kim, 홍준표Chun Pyo Hong
Abstract
Solar cell was made from 1 ohm·cm polycrystalline silicon which had been directionally solidified using split, reusable graphite molds coated with Si₃N₄. Silicon n/p homojunction solar cell was fabricated through the following steps; wafer slicing, texturizing etch, P diffusion, anti-reflection coating application, grid formation and contact annealing. The cell area was 9㎠. Under the airmass 1.5 illumination, a short circuit current of 0.232A and an open circuit voltage of 0.582V were obtained with a curve fill factor of 0.666. The maximum energy conversion efficiency was 10.0% under standard terrestrial test conditions (AM 1.5, 100mW/㎠).
