Enhanced Electron Photoemission by Collective Lattice
We propose to use collective lattice resonances in plasmonic nanoparticle arrays to enhance and tailor photoelectron emission in Schottky barrier photodetectors and solar cells. We show that the interaction between narrow-band lattice resonances (the Rayleigh anomaly) and broader-band individual-particle excitations (localized surface plasmon

In the case of the FTO/TiO 2 /Sb 2 S 3 /SbSI/PCPDTBT/Au solar cell the charge transfer was even more effective due to an existence of energetically favorable external driving force. Thus, the PCE of this solar cell reached 6.08%, which is the best result among the antimony chalcohalide photovoltaic devices developed so far (Table 5.3).

6 FAQs about [Photodetectors and solar cells]
Are solar cells photodetectors?
Abstract: Solar cells are not strictly photodetectors, in the sense that they convert radiant power to an electrical power supply rather than to an electrical signal carrying information like all other photodetectors considered so far.
What is the dark current in a photodetector?
The dark current in a photodetector is the current present even in the absence of light and limits its sensitivity I = -(Io + IL) I_o I_L _ Dark current is caused by thermal generation and device leakage current kT e o i i c v g I_A n^2_ where n^2_ is the density of charge carriers in the intrinsic semiconductor.
Are solar cells the same as photodiodes?
However, solar cells are very similar to and share many of the problems of photodiodes, and because of their engineering relevance for electrical utilities and stand‐alone power supplies, the authors present in this chapter a brief outline of devices, technologies, and systems.
Can photodiodes be used as solar cells?
Photodiodes can be used as solar cells to convert solar energy to electrical energy. Consider the solar cell connected in a circuit, as shown below. R . The solutions, corresponding to the intersection of the curves, represent the operating points of the cell. Note that the pn junction in a solar cell is always forward biased.
