Technology Description

The technology is- development of Holographic Solar Modules for high efficiency solar energy conversion. A hologram is a diffracting element that can do multiple functions such as light concentration, wavelength selection etc. In the proposed system the holographic element concentrates and spectrally split the light radiation so as to effectively couple the energy to a multi-junction solar cell. This ensures cool concentrated light with tuned spectral distribution, optimum for the multijunction cell. Also, instead of stacking the multi-junction layers, the layers can be linearly distributed. The innovation uses a high efficiency and stable holographic material in conjunction with the high efficiency multijunction solar cells.

Applications

Since this is an innovation to double up the yield of present day solar modules, with no additional cost, if mass produced, there are lots of real life applications. Successful commercialization will redefine household and industrial energy use. The enhanced yield will help to popularize solar energy use and thereby will help to reduce the carbon foot-print.

Benefits

Efficiency of conventional commercial grade solar cells is about 15% and successful realisation and commercial production of the proposed solar modules will improve the efficiency of solar energy conversion by about two times.
