Abstract

Nowadays, available PV modules are flat. The PV presented in this chapter is a glass tube with a flexible PV cell inside. The tubular diversification of the PV was initially inspired by the start-up company Solyndra in Silicon Valley CA, which manufactured CIGS cell directly on the surface of an inner glass tube. Unfortunately, Solyndra went bankrupt due to high manufacturing costs. In 2011, a leaner tubular PV was invented at Gate-East in Garching, which enabled substantial simplification compared to the Solyndra's ideas and design. It was named Augsburger Tubular Photovoltaics (ATPV) and patented with Osram, later Ledvance. It has numerous advantages as follows: the cell manufacturing is roll-to-roll technology, the absorption films can be thinner at the same efficiency, because the tubular shape extends the light path, compared to flat cells and modules. Simplified installation and operation: low weight; semitransparent for rain, wind, and snow; better cooling compared to a flat panel; leaner and cost-effective substructure. Agricultural application: protection against hail but permeability for sun and rain—homogenous plant growth as general: reduced evaporation, short-period shade and therefore, uniform growing; good protection at high temperatures and from destructive hail—dual as well as multiple use is possible. The concept of ATPV was successfully proven, and a small-scale manufacturing was built at the Osram, later Ledvance site in Augsburg.
