The design and construction of an integrated ultra-high vacuum system to produce and characterize organic small-molecule solar cells is presented. Through the new system, it is possible to produce several solar cells simultaneously on the same ITO substrate via organic molecular beam deposition under vacuum conditions. In-situ electric contact is achieved through aluminum deposition. With the sample holder the temperature can be systematically modified between 200 K and 700 K while liquid nitrogen cooling or resistive heating to control the deposition process and to permit temperature dependent measurements.
We present first results for OPV cells of diindenoperylene (DIP)/C60 (see Ref. [1] for complementary results) and DIP/perfluoropentacene (PFP).
