The modern Military has an ever-increasing need for power, in particular light-weight portable power with high power densities and decreased deployed foot print. Currently packable panels are made from light weight Amorphous Silicon or carbon fiber backed crystalline silicon. The challenge for the amorphous silicon technology resides in the power conversion efficiency watts per unit area while the carbon fiber backed crystalline silicon, cells lack field durability and flexibility. The solution to this is to take the benefits of the two different technologies and combine them to produce a solar fabric that has high power conversion and ultra-flexibility. To achieve the two greatest challenges of this project, compound curve tolerance and high efficiency, PowerFilm proposes the following solution to make an ultra-flexible photovoltaic sheet on a flex substrate with tiles of high efficiency crystalline silicon.
