Many avenues are being explored to find alternative energy sources and to increase the efficiency of the resources we are already using. The field of efficiently utilizing solar radiation is one of the most promising today because of the large amount of sunlight available on this planet. Conventional solar power technology has two main drawbacks. The cost of manufacturing the components used in solar cells is high, and the efficiency of these devices is low. The use of nano technology is being investigated as a way to overcome these drawbacks. Nano particles have unique qualities which enable them to be tuned to absorb a wider range of wavelengths available in sunlight, thereby increasing efficiency. Their use lowers the cost of manufacture. This paper will explore the possibilities that nano particles offer to the field of solar energy
