Stability Tests on Indoor Dye PV Modules

Environmental and accelerated ageing tests were performed on the indoor dye modules described in Sect. 7.6 in order to detect failure mechanisms. Contrary to expectations, many modules survived humidity/freeze cycling tests (10 cycles, 85%, 20 h at 55°C per cycle) without major degradation, demonstrating the capability of the sealing concept (see Fig. 7.8). This was also true for temperature cycling (between —5 and 55°C). However, it has

been shown from accelerated testing (strong continuous illumination under a fluorescent lamp, including UV-B light) that UV light in particular is a serious degradation factor. Efficient UV filters are therefore recommended in order to prevent fast degradation of UV critical components in the cell [17].
