Аннотация
The performance of InGaN/GaN multiple quantum well (MQW) solar cells with five different Si-doping concentrations, namely 0, 4 × 1017 cm–3, 1 × 1018 cm–3, 3 × 1018 cm–3 and 6 × 1018 cm–3, in GaN barriers is investigated. Increasing Si-doping concentration leads to better transport property, resulting in smaller series resistance (Rs). However, the crystal quality degrades when Si-doping concentration is over 1 × 1018 cm–3, which reduces the external quantum efficiency, short circuit current density and open circuit voltage. As a result, the sample with a slight Si-doping concentration of 4 × 1017 cm–3 exhibits the highest conversion efficiency.
