A solar cell simulator that is cylindrically symmetrical to test photovoltaic devices that are flexible. A particular embodiment would be made from plexiglass or similar acrylic material. The present invention produces a spectrum that simulates the spectral distribution of solar light that we observe on the Earth's surface. The simulator would be comprised of a tubular pulsed light source, a pulsed power supply, a tubular light spectrum filter, an IV electrical measurement station, a cylinder-shaped module holder to place the flexible large-area module during the measurement. All cylinders share the same central axis. This maintains radial uniformity of all light intensity and can be used for electrical measurements (IV curves under illumination) of flexible large-area PV modules.

Apparatuses and methods are provided for the continuous, roll-to-roll formation of photovoltaic (PV) cells. Apparatuses include reel-to-reel transport chambers, one or more deposition chambers, a differential process isolation unit and a chamber for obtaining real time quality data, including IV data, yield data and uniformity data.
