Performance rating of the larger PV cell for solar and indoor lighting measurement

The use of special high-efficiency solar cell, such as perovskite, HJT, is due to the individual measurement. After the development, the efficiency is difficult due to hysteresis effect. In order to effectively reduce the cost of solar cell systems and improve power generation efficiency based on traditional silicon solar technology, the development and mass production of large-size solar cells has also become the main axis of the international trend in recent years. However, as the size of solar cells increases and the diversification of solar cell designs increases, measurement problems also arise. Therefore, in this study, we look the measurement topics include how to develop the lighting simulator for Class 3A. And how to accurately calibrate the cell efficiency measurement technology of large-size solar cell.
