| Popis: | The enhancement of photovoltaic (n-p/Si solar cell) has been carried out. The development is based on a surface texturing of the solar cell. The photochemical etching technique was used in the preparation of the n-side of silicon solar cell. The samples were exam were by Atomic Force Microscope ( AFM) which show that the average pores diameter in the order of 55nm, and the thickness of the etched layer changed from 1.1nm to 56nm, which cause increase the surface area of the silicon solar cells that expose of the to the illumination. The efficiency conversion of the photovoltaic (PV) was tested showing an enhancement to the change on efficiency of the silicon solar cells, the best efficiency was obtained by treating the solar cell to a solution of 15% of HF acid concentration with period of 45 minutes, with a value of (12%) while the untreated solar cell efficiency was (8.1%). The Morphological Investigation shows that the etching rate is accretion with increasing of the treatment time, but after 45 minutes the first layer of the silicon solar cell was removed which caused declining in the efficiency, the nanosize of pores and the area expose to illumination. |
