摘要

本文研究了用简单激光掺杂工艺(LD)制备的选择性发射极(SE)太阳能电池中薄膜电阻的影响。为了证明轻掺杂辐射源对POCl3扩散的影响，我们将细胞分为三组，片电阻分别为100 Ω/sq (SE-1)、120 Ω/sq (SE-2)和140 Ω/sq (SE-3)。激光掺杂后，银电极接触片电阻为~60 Ω/sq。当片电阻值为60/120Ω/sq时，最佳电池效率(η)为20.11%，开路电压为650 mV。

Effects of sheet resistance on selective emitter solar cells by laser direct doping

This article investigates the effects of sheet resistance on a selective emitter (SE) solar cell fabricated using a simple laser doping process (LD). In order to demonstrate the influence of lightly doped emitter we divided cells for three groups for POCl3 diffusion with sheet resistance of 100 Ω/sq (SE-1), 120 Ω/sq (SE-2) and 140 Ω/sq (SE-3). After laser doping, the sheet resistance is ~60 Ω/sq for silver electrode contact. The optimal cell with sheet resistance values of 60/120Ω/sq showed the best efficiency (η) of 20.11 %, open circuit of 650 mV.
