Performance degradation is one of the crucial difficulties for the market of organic solar cell (OSC) devices. These deteriorative characteristics can be attributed to many factors, mainly to the chemical reactivity of the device multiple layers with the environment. Here, we investigate the performance of a standard OSC device made of the polymer poly(3-hexylthiophene-2,5-diyl) and the fullerene [6,6]-phenyl-C61-butyric-acid-methyl-ester (P3HT:PCBM) as a photoactive layer in a high humidity environment (53%) within 100 days divided into three periods. The results confirm that the OSC devices’ encapsulations should be completed immediately after the fabrication due to fast chemical degradation of the photoactive layer, which reduces the Jsc by 15% after 40 mins of fabrication. We also found that the FF has been reduced by 17.36% from its initial value after 1152 hours due to a deficiency of the interfacial charge transfer between the multiple layers of the device. Finally, the performance of the device’s decays to zero after 2400 hours.

This work presents the results of the exposure of soda-lime, potash-lime and mixed-alkali silicate glasses during ten and twenty months in different Portuguese monuments with historical stained-glass windows to characterize the influence of local environmental conditions. The glass samples were exposed in the Monastery of Batalha (Batalha), the Monastery of Jerónimos (Lisbon), and the Cathedral of Évora (Évora). A set of analytical techniques to assess the physicochemical effects were used, including optical microscopy and Fourier transform infrared spectroscopy. All the samples presented crystalline deposits on their surface; however, their quantity and nature depended on the atmospheric conditions during the days before the collection. Potash-lime silicate glass was the most altered glass in comparison with soda-lime and mixed-alkali silicate glasses. The samples from the Cathedral of Évora showed a high content of dust and salts on their surface but without severe chemical pathologies; however, those samples exposed in the Monastery of Jerónimos and the Monastery of Batalha presented alteration layers due to a high humidity environment.
