Özet

The last generation photovoltaic devices aim to tackle the losses associated with the nonabsorption of below bandgap photons and the thermalisation of above bandgap photons to the band edges. In this chapter, numerical analysis were carried out on the intermediate band solar cell (IBSC) that absorbs the subbandgap photons by the help of the intermediate band (IB) inserted inside the base region of n+-i-p+ structure and increases the photocurrent without decreasing the output voltage. The operation performance of IBSC has been investigated using the detailed balance equations.
