Fabrication of air-stable, large-area, PCDTBT:PC70BM polymer solar cell modules using a custom built slot-die coater
文摘
The design of a fully functioning lab-scale slot-die coating equipment is shown and its open-source documentation is provided. The custom built coating equipment is used to fabricate PCDTBT-PC70BM-based PSC modules with photoactive areas above 35 cm2 and efficiencies exceeding 3%. The quality of the slot-die coated layers was extensively characterized with electrical and optical spatial mapping techniques, such as LBIC, PL, and Raman. The operational stability of the modules was studied under constant irradiance of 100 mW/cm2 for 24 h under ambient conditions.
