Abstract

Crystalline silicon (c-Si) wafers are the dominating substrate materials for solar cells in current photovoltaic (PV) industry. Silicon (Si) wafer with positive-type (p-type) based solar cells dominates almost 95% of the global PV market. Recent goal in Si solar cell industry is focusing on cost reduction through inexpensive manufacturing processes. Standard manufacturing process of Si solar cell fabrication consist of damage removal, cleaning, texturing, phosphorus oxytrichloride (POCl3) diffusion, anti-reflective coating (ARC) deposition, metallization by screen printing technique, firing and light current-voltage (LIV) testing. These fabrications line are time-consuming and high temperature process which lead to high manufacturing cost. This study presents the simplification of Si solar cell fabrication on p-type Si wafer. Simplified fabrication process eliminates the ARC deposition by plasma enhanced chemical vapour deposition (PECVD). Simplified Si solar cell was fabricated without silicon nitride (SiN) as ARC layer. In commercial solar cell, both pyramid texture on Si wafer and SiN have been used to reduce reflectance and enhanced the light absorption. From the reflectance measurement, it can be seen that SiN and pyramid texture shows an average reflectance curve. The efficiency obtained by commercial, fabricated and simulated solar cells were 17.09%, 9.44% and 9.67%, respectively. From the simulation study, it is proven that the low efficiency of simplified solar cell was attributed by low minority carrier lifetime of p-type Si wafer.
