The optimized texturing angle for triangular texturization in multicrystalline silicon solar cells

In this paper, we introduce the possible texturing methods and their effects on the performance of multicrystalline silicon solar cells. A 2-D process and device simulator is used for this purpose and the resultant efficiency increase is studied. The optimized texturing angel is deducted by theoretical calculations of ray tracing. Theoretical calculations show that the best texturing angle to have the highest efficiency is 52.7° which is in agreement with the results obtained by 2-D process and device simulation. Simulation results show about 0.5-0.8% increase in the total efficiency depending on the method of texturization in multicrystalline silicon solar cells.
