Standard photovoltaic solar cells (PV cells) use only about half of the light spectrum provided by the sun. The infrared part is not utilized to produce electricity. Instead, the infrared light heats up the PV cells and thereby decreases the efficiency of the cell.

Thus, for the absorption of the full above bandgap solar spectrum, GaAs solar cells can be made thin, typically in the order of a few hundred nanometers to a couple of micrometers, 15 while silicon solar cells have to be significantly thicker, typically in the range of 100–500 μm. 16.
These kinds of solar cells have been stymied by the fact that light quickly breaks them down after not much use. The AI model developed more stable organic light-harvesting molecules.
The spectral response is conceptually similar to the quantum efficiency. The quantum efficiency gives the number of electrons output by the solar cell compared to the number of photons incident on the device, while the spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell. A spectral response curve is shown below.
Solar cells are semiconductor-based devices primarily, which convert sunlight directly to electrical energy through the photovoltaic effect, which is the appearance of a voltage and current when light is incident on a material.The photovoltaic effect was first reported by Edmond Becquerel in 1839, who observed a voltage and current resulting from light incident on …
These cells absorb between 300 and 800 nm so like other nanostructured and thin film technologies could benefit from a UC (and/or DC) layer in order to use a greater portion of the solar spectrum.
