Abstract/Summary:

---

In this work, we propose an approach for integrating crystalline silicon solar cells into flexible and light-weight structures targeting applications away from more standard solar cell module installations as BIPV and ground-mounted solar cell power plants. For our experiments, we do a very similar layup and laminations as for standard modules, leave out the glass on front side and set out PET film. For the strings, standard tabbing-stringing of 3-busbar multi-crystalline Al-BSF solar cells. We made 2×2 cells laminated modules, called “4-cell module”. The 4-cell module structure is PET/EVA/multi-crystalline Al-BSF cells/EVA/PET. After standard laminations, each sample was IV-measured and EL analyzed. 4-cell module was set on the measurement stage with a structure of 200 mm radius of curvature and measured IV-properties. We compared the IV properties with flat condition and curved conditions. The current value with curved conditions was lower than that with flat conditions due to the decrease in the irradiation area. However, no significant changing was observed in the values of voltage and FF. By EL analysis, there is no crack after curved conditions.
