The current–voltage ( IV) values of solar cells represent the heart of their characterization in industry and research. In the current state-of-the-art, the cell is automatically contacted with some contact bars on the front and back side, whereupon the IV characteristic can be measured.
A contactless method for current-voltage testing of silicon solar cells is proposed. It may reduce cell breakage and costs. It may improve line throughput and light homogeneity and gives extra information. The method combines four contactless measurement techniques. The proof of principle of the method is successfully demonstrated for 3 cell types.
These techniques have been adequately modified, extended to cover the case of solar cells and used to extract the parameters of interest from experimental I-V characteristic of a Poly-Si solar cell under dark condition.
The current–voltage measurement is the most important measurement in solar cell quality control. As the contacting process of cells results in mechanical stress and consumes a significant amount of measurement time, this work presents an IV characterization based on contactless measurements only.
For measuring the IV curve of solar cells, the cells are generally mounted on vacuum chucks, which often contain an active cooling and heating unit to precisely regulate the solar cell temperature to 25 °C. This is particularly important for steady-state simulators, which exhibit a significant heat transfer to the cell.
