Photovoltaic (PV) cells convert the energy of solar or other light sources to electricity. The power conversion efficiency (PCE) of PV cells can be calculated by using Equation 1, where P out is the maximum of the electrical output power density of a PV cell and P in is the input light power density. PCE is the most important parameter of PV cells.
However, there are many technologies that may not require light beyond 900 nm—amorphous silicon, cadmium telluride, DSSCs, OPV cells and PSCs are examples —although PbS quantum dot solar cells do require light up to 1200 nm. Hence it should be recognized that there may be light sources that could generate a reasonable emission …
