Results of organic solar cells measurements with different internal architecture (standard and inverted) for two active layers materials: well-know PTB7-Th:PC70BM and state of the art PBDB-T-2F:BTP-4Cl-12. Every cell configuration was examined by I-V characteristics measurements under solar light simulator (AM 1.5G) for freshly made devices and after long term ageing storage. Additionally optical absorbance measurements was performed for both active layer materials. For inverted architecture 3 different electron transport layers was tested (ZnO and TiOx by spincoating technique and ZnO by ALD technique).
Standard architecture: Glass/ITO/PEDOT:PSS/active_layer/Al
Inverted architecture: Glass/ITO/ZnO or TiOx/active_layer/MoOx/Al
