Abstract
An organic photoelectronic device may include a photoelectronic conversion layer between a first electrode and a second electrode and a buffer layer on the photoelectronic conversion layer. The photoelectronic conversion layer may be between a first electrode and a second electrode, and the buffer layer may be between the first electrode and the photoelectronic conversion layer. The photoelectronic conversion layer may include at least a first light absorbing material and a second light absorbing material configured to provide a p-n junction. The buffer layer may include the first light absorbing material and a non-absorbing material associated with a visible wavelength spectrum of light. The non-absorbing material may have a HOMO energy level of about 5.4 eV to about 5.8 eV. The non-absorbing material may have an energy bandgap of greater than or equal to about 2.8 eV.
