Semitransparent inverted bulk-heterojunction solar cells were fabricated on an ITO/glass substrate utilizing oxide/metal/oxide transparent anode. The device structure was glass/ITO/PFN/PTB7:PC71BM/MoO3/Au/MoO3. The semitransparent solar cell showed a transparency of 44% at 550 nm and bifacial power generation at both front and backside illumination. The power conversion efficiencies (PCEs) with light illuminated from ITO or Au/MoO3 side were 2.8% and 2.3%, respectively. Fabrication of stacking structure of two separated solar cells was further demonstrated to harvest an increased amount of photons and enhance the PCEs. The stacked cells showed a transmittance of 17% at 550 nm and improved PCE of 3.3% when connecting two cells in parallel.
