概要
- 論文の詳細を見る
High-efficiency silicon solar cells are fabricated with back-surface-field (BSF) structures using medium-resistivity, float-zone substrates. The cell processes are optimized using a new BSF process in order to maintain a high minority-carrier lifetime. In addition, they are improved with a passivated, V-grooved surface to enhance collection efficiency. The resultant cells exhibit conversion efficiencies of 19.1% with a short-circuit current density of 38.4 mA/cm^2. The minority-carrier lifetime and surface recombination velocity are estimated to be 341 μs and 3×10^5 cm/s using a computer program.
