Fabrication of Light Trapping Thin Film Structure for Efficient Si Solar Cell by Laser Treatment

Saad A. Mohammed Salih | Baraa F. Abdul Ameer

Abstract: Surface texturization became known as an important field of research with a broad range of applications in solar cells, electronics, and sensors. In this work, short-pulse NdYAG second harmonic nanosecond laser with different energies (600, 700, 800 and 900mJ) has been used to produce micro- and nano-scale surface textured patterns in a thin SiO2 film formed on the (100) orientation of c-Si solar cell substrate of small areas (21 cm2). The topography of laser textured surfaces were investigated depending on several test devices as FTIR, optical microscopy and AFM. The electrical parameters of manufactured solar cells were characterized by measurements of I-V parameters illuminated under standard AM 1.5 radiation. Results show a very good improvement of the efficiency of the solar cell textured by this method. This is achieved by (9.6 %) efficiency compared with (3.34 %) for the ordinary silicon solar cell when applying (900mJ) laser energy.
