Donor/Acceptor Heterojunction Organic Solar Cells

2020

The operation and the design of organic solar cells with donor/acceptor heterojunction structure and exciton blocking layer is outlined and results of their initial development and assessment are reported. Under halogen lamp illumination with 100 mW/cm2 incident optical power density, the devices exhibits an open circuit voltage VOC = 0.45 V, a short circuit current density JSC between 2 and 2.5 mA/cm2 with a fill factor FF &asymp

Fabrication and characterization of Donor/Acceptor heterojunction organic solar cells

2018

Results of initial development of organic solar cells having the Donor/Acceptor heterojunction structure with and without an exciton blocking layer are reported. Characterization is carried out in AM1.0 condition with 100 mW/cm2 incident optical power density. The best device has the exciton blocking layer and exhibits an open circuit voltage VOC = 0.43 V, a short circuit current density JSC = 2.35 mA/cm2 with a fill factor FF ≈ 50%, an external quantum efficiency (electrons/s over incident photons/s) EQE ≈ 5% and a power conversion efficiency of about 0.5%.
