Improved upconversion using solar concentrators Efficiency of solar cells can be increased by concentrating incident sunlight on solar cells. Thus the cost of solar cell technology can be reduced.
An altogether different kind of approach is used in this method. In this process, temperature of substance is raised by using incident light thermal radiations. Thus black body radiation spectrum of material is shifted to shorter wavelength side. These shorter wavelength photons are used to increase efficiency of solar cells.
Incident solar spectrum on solar cells can be modified and thus photon conversion efficiency of solar cells can be increased using Upconversion and Downconversion materials.
Total amount of energy incident on a solar cell is not 100% converted into electrical energy. There are several energy losses inherent in this process. The major portion of the energy is lost because of heat generation and thus leading to temperature increase of solar cell causing inevitable decrease in efficiency of solar cells.

Space solar spectrum is different and solar cells could have better efficiency in space due to no atmospheric effect there. Capturing the total solar spectrum is the necessity to achieve higher output voltage in photovoltaic effect. The output of a solar cell depend on irradiance of solar spectrum as well as number of junctions in the solar cell.
