This increases the induced photocurrent and thereby efficiency. Therefore, there is a net rightward photocurrent. The overlap between these two spectra determines the maximum possible photocurrent. The reverse bias also creates dark current without much change in the photocurrent. The photocurrent still contains shot noise. Essentially, the electron could reach the IB before recombining, leading to a higher induced photocurrent. The resulting current "I" is called the generated photocurrent. In that case, space-charge limited photocurrent (SCLP) hampers device performance. The short circuit current (Jsc), is the maximum photocurrent generation value. The photocurrent of just one photon can be registered with these electronic devices. Excitons generated within this length close to an acceptor would contribute to the photocurrent. Actually, neglecting the formula 42 term in the Hamiltonian, we are disregarding possible photocurrent contributions. Photocurrent caused by ultraviolet and x-ray radiation may belong to this category as well. Thus, photocurrent matching is very important for the construction of highly efficient tandem pn-DSCs. For example, at the level of the retinal cones, the response might be in photocurrent.
