Multi junction solar cell diagram.

Multi junction cell efficiency has now reached 44 in production cells. At present the fresnel lens are commonly used as the condenser in high concentrating photovoltaic hcpv modules. High efficiency multijunction devices use multiple bandgaps or junctions that are tuned to absorb a specific region of the solar spectrum to create solar cells having record efficiencies over 45. It is ideally believed that the output power of a iii x2013 v triple junction solar cell which is placed on the focal plane of a fresnel lens is the largest because the intensity of the sunlight on the focal plane is the largest.

A solar cell is basically a junction diode although its construction it is little bit different from conventional p n junction diodes a very thin layer of p type semiconductor is grown on a relatively thicker n type semiconductor we then apply a few finer electrodes on the top of the p type semiconductor layer. Schottky junction solar cell wikipedia. A multi junction solar cell is a tandem solar cell with more than one p n junction. These electrodes do not obstruct light to reach the thin p type layer.

In practice this means that there are multiple layers of different semiconductor materials each of which produces electric currents in response to different wavelengths of light. Actually according to our work the dispersion.
