Of coruse, you could use actual sunlight, but this would introduce an uncontrollable variable. To test solar cells reliably, you need to maintain controlled conditions within your lab — and this is impossible to do while allowing direct, unfiltered sunlight onto your testing equipment.
To conduct a more in-depth characterization or to test how stable your device performance is, you could do either maximum power point tracking or current. The I-V curve is the standard measurement in PV research and, when done correctly, can quickly and accurately measure the performance of a photovoltaic device.
To test solar cells reliably, you need to maintain controlled conditions within your lab — and this is impossible to do while allowing direct, unfiltered sunlight onto your testing equipment. Additionally, many potential solar cell materials are unable to withstand weathering effects during the early stages of development.
