PROBLEM TO BE SOLVED: To provide optoelectronic devices having high electric conversion efficiency and performance.SOLUTION: An optoelectronic device comprises a photovoltaic cell. The photovoltaic cell comprises a space-charge region, a quasi-neutral region, and a low bandgap absorber region (LBAR) layer or transport (IT) layer at least partially positioned in the quasi-neutral region of the cell and having improved charge carrier transport properties in an emitter layer or base layer and a lower bandgap than an immediately adjacent semiconductor layer. |
