[10] discovered that the output current of their new
multijunction solar cell decreased slightly on the designed focal plane of the lens.

multijunction solar cell enabled by a silicon tunnel junction," Applied Physics Letters, vol.
Introduction of tunnel junctions between subcells is the way of monolithically building a
multijunction solar cell. These tunnel junctions must cause minimum losses of the conversion efficiency.
Considering the
multijunction solar cell response, we are only interested in wavelength range of 350-1750 nm [17].

[1] and Cotal and Frost [2] who developed a theoretical thermal model for predicting the temperature of a
multijunction solar cell based on passive cooling systems.
Enhancement of the device performance in
multijunction solar cell compared the single junction one, the materials are selected in such a way to utilize the solar spectrum as well as to avoid the energy loss in a solar cell.
The interface phenomena may affect the charge carrier transport in the Ge subcell as well as in the whole
multijunction solar cell.
High conversion efficiency is very important for solar cells, and the
multijunction solar cell is a very promising approach from the point of view of high performance.

However, a single step wet-etch for MJSC has not been reported yet since the different etch selectivities of the various III-V layers building up the
multijunction solar cell structure add complexity to this process.
