The purpose of this experiment is to understand the working principle of solar cells, to measure the volt-ampere characteristics of solar cells and to evaluate the efficiency of solar cells.
1. Understand the working principle of solar cells: Through experiments, you can gain an in-depth understanding of how solar cells convert light energy into electrical energy and their internal working mechanisms.
2. Measure the volt-ampere characteristics of solar cells: By measuring the voltage and current relationship of solar cells under different lighting conditions, we can understand their volt-ampere characteristics, which is an important indicator for evaluation. the performance of solar cells.
3. Evaluate the efficiency of solar cells: through experiments, the conversion efficiency of solar cellscan be calculated, that is to say the ratio between the electrical energy generated per unit of time and the incident light energy. indicator to evaluate the performance of solar cells.
