Abstract EN
The subject of the present work is to develop a simple and effective method of enhancing conversion efficiency in large-size solar cells using multicrystalline silicon (mc-Si) wafer.
In this work, industrial-type mc-Si solar cells with area of 125×125 mm2 were acid etched to produce simultaneously POCl3 emitters and silicon nitride deposition by plasma-enhanced chemical vapor deposited (PECVD).
The study of surface morphology and reflectivity of different mc-Si etched surfaces has also been discussed in this research.
Using our optimal acid etching solution ratio, we are able to fabricate mc-Si solar cells of 16.34% conversion efficiency with double layers silicon nitride (Si3N4) coating.
From our experiment, we find that depositing double layers silicon nitride coating on mc-Si solar cells can get the optimal performance parameters.
Open circuit (Voc) is 616 mV, short circuit current (Jsc) is 34.1 mA/cm2, and minority carrier diffusion length is 474.16 μm.
The isotropic texturing and silicon nitride layers coating approach contribute to lowering cost and achieving high efficiency in mass production.
