The basic components for most secure computing and communication systems of today are random number generators. The present work purports to a radically novel approach to the design and implementation of random number generators. Firstly, a nonlinear analysis of the photovoltaic cell open circuit voltage is performed, and the presence of chaos is ascertained using standard measures such as Lyapunov Exponents. Following this, the chaotic output is adapted into a bit stream and randomness tests from the NIST Suite are performed. It is seen that the chaotic output indeed passes all the randomness tests. The histogram of the output reveals similarities with Gaussian Normal Distributions, confirming the stochastic nature. Thus, the photovoltaic cell output is a potential power generating random number generator, drastically differing from the conventional power dissipative random number generators.
