“…[199] Gholamkhass and Holdcroft replaced part of the PEDOT:PSS with gold nano-dots to improve device stability in accelerated aging tests. [200] While UV irradiation generally degrades polymer photovoltaic devices through photo oxidation reactions of the active layer it has been argued that UV treatment of the PEDOT:PSS layer actually increases the lifetime. [201] Mixed oxides (WO 3 -V 2 O 5 ) have been used by Huang et al to replace PEDOT:PSS creating air stable inverted devices.…”

Organic photovoltaics (OPVs) evolve in an exponential manner in the two key areas of efficiency and stability. The power conversion efficiency (PCE) has in the last decade been increased by almost a factor of ten approaching 10%. A main concern has been the stability that was previously measured in minutes, but can now, in favorable circumstances, exceed many thousands of hours. This astonishing achievement is the subject of this article, which reviews the developments in stability/degradation of OPVs in the last five years. This progress has been gained by several developments, such as inverted device structures of the bulk heterojunction geometry device, which allows for more stable metal electrodes, the choice of more photostable active materials, the introduction of interfacial layers, and roll-to-roll fabrication, which promises fast and cheap production methods while creating its own challenges in terms of stability.

“…In small‐molecule solar cells stability has been enhanced by using a polymerized fluorocarbon anode buffer layer between the ITO and the copper phthalocyanine/C 60 active layer 199. Gholamkhass and Holdcroft replaced part of the PEDOT:PSS with gold nano‐dots to improve device stability in accelerated aging tests 200. While UV irradiation generally degrades polymer photovoltaic devices through photo oxidation reactions of the active layer it has been argued that UV treatment of the PEDOT:PSS layer actually increases the lifetime 201.…”

Autoclave methods are commonly used when pressure progress under thermal stress is of interest. One of them is the mini‐autoclave method by Kühner AG. To test the robustness of the equipment under powerful exposure, two known high energetic materials, DNT and TNT, were investigated. The sample mass was increased stepwise in the range from 0.25 g to 1.0 g. For one test (1 g TNT), gas burners instead of the usually employed 2‐zone heating block, were used to intensify the test conditions. Results showed the expected slower pressure generation of DNT in comparison to TNT. The mechanical robustness of the apparatus could be approved in all runs. Pressure data were used to calculate the energy release of decomposition. The values were in good agreement with the heat of decomposition, estimated by DSC.

“…Ag has a strong resonance and low absorption in the visible and near infrared part of the spectrum [13,14]. The power conversion efficiency (PCE) was enhanced by the reduction of the series resistances by the metal NPs, which improved charge collection at the cathode contact [15]. The PCE of single-junction OSCs has been limited.…”
