Abstract

In the previous chapter, we discussed the conditions that apply to the actual solar cell but were not considered for the ideal solar cell. In order to derive the maximum output power of the actual solar cell, we have to discuss the balance between absorption (resulting in electrical current) and emission (due to the established voltage). Therefore, the present chapter discusses the balanced condition of voltage and current by employing the current–voltage relation determined in the previous chapter. Based on that, the conversion efficiency of the actual solar cell is derived. Then, we discuss the contributions of the different types of losses that occur in a solar cell with a single band gap.
