1. The overlap between these two spectra determines the maximum possible photocurrent . 2. The induced photocurrent can then be amplified and measured. 3. Excitons generated within this length close to an acceptor would contribute to the photocurrent . 4. Therefore, there is a net rightward photocurrent . 5. This enhances transport of electrons and internal quantum efficiency ( IQE ) and photocurrent . 6. In this mode the diode is often dark current without much change in the photocurrent . 7. In that case, space-charge limited photocurrent ( SCLP ) hampers device performance. 8. This increases efficiency through increased photocurrent . 9. For example, at the level of the retinal cones, the response might be in photocurrent . 10. Thus, photocurrent matching is very important for the construction of highly efficient tandem pn-DSCs.
