Reflectivity Study of Acid Textured Multicrystalline Silicon Wafers in Different Solutions for Solar Cells Application |
| 초록 |
In this paper, an attempt was made to reduce the optical loss of multicrystalline silicon (mc-Si) wafer. The texturization of wafer was carried out in acidic solution by controlling the chemical compositions and temperatures. The two different acidic solutions of HF:HNO3:H3PO4 and HF:HNO3:H2O used and examined with respect to the etching time.The minimum (~ 17%) and maximum reflectivity in HF:HNO3:H3PO4 solution obtained by 10 s and 16 s respectively, indicating the smoothness of surface increased with the increase of etching time. The reflectivities in HF:HNO3:H2O solution minimized to ~5%. The reflectivity was reduced by the replacement of H3PO4 to H2O and thus obtained the minimum reflectivity. |
