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.
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. These losses and their minimization play an important role in solar to electrical energy conversion.
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.
Downconversion helps to improve efficiency of poor-UV response solar cells like crystalline Silicon, CdTe and CIGS coated solar cells . Using nano-engineered phenomenon like photonic crystals for UC materials and plasmonic resonance, integrated with solar concentrators, spectral conversion efficiency of solar cells can be improved.
Applied as an inexpensive coating, it could increase the fraction of solar energy converted to electricity in silicon cells by as much as 25%. Today’s solar photovoltaic cells waste a large fraction of the energy that is abundant in sunlight. They absorb a range of wavelengths, typically from the blue to the near infrared.
