Tandem Solar Cell—Concept and Practice in Organic Solar Cells

Photovoltaic is a process that converts photons directly to electrons, i.e. light to electricity. Semiconductors are the suitable materials for this purpose. Followed by the invention of first modern solar cell in Bell lab in 1954 [], there have been intensive efforts to investigate how efficient, in ideal operational condition, a photovoltaic cell could be to …

in the particular case of sensitized solar cells. In fact, Si solar cells have a similar selectivity mechanism where the band bending produced by the p-n junction is limited to a very narrow interfacial layer, significantly thin in comparison with the whole absorber thickness. There are also intermediate models between those two noted in Figure 1.

In comparison, the working principle of this solar cell is quite different from perovskite solar cells and inorganic p–n junction solar cells. When OPVs are illuminated, a localised and strongly bound exciton (i.e. a bound electron–hole pair) is generated, with the electron in the LUMO (lowest unoccupied molecular orbital) and the …

How Do Perovskite Solar Cells Work?

Nevertheless, the presence of an electric field is not the only way to obtain contact selectivity. It can also be attained by a preferential kinetic exchange at one selective contact of carriers of one kind while the other kind is blocked. Figure 1 C is an example of this, where light is absorbed by a dye molecule layer and electrons are selectively …
