Steps to minimize the characterization errors in steady state IV curve measurements taken with C.O.T.S. equipment

The continuing search for clean energy solutions is driving a huge increase in the number of laboratories, non-profit and commercial, working on solar cell development. These laboratories need to characterize their solar cells in order to steer their development process. The most popular method is the measurement of the current voltage curve, better known as the IV curve. IV curves can be measured by Commercial Off The Shelf (COTS) equipment which typically consists of a steady state solar simulator, a probe station, an electronic load, a reference cell, and software driven data-acquisition and analysis means.
