A CdTe layer can be produced with Close Space Sublimation (cSS) and Vapor Transport Deposition (VTD), depicted in the figures below. In this question you will calculate the production rate and throughput for each of the methods. Please note that the numbers are illustrative. Close Space Sublimation Vapor Transport Deposition First Solar (2016) A) A CSS chamber can produce a homogeneous CdTe layer a on substrate of 4.2 m². This process takes 435 minutes, excluding loading and unloading of 15 minutes. The substrate is cut into smaller modules with a total power at STC of Pmpp = 750 Wp. The machine has a downtime of 4% on a yearly basis for cleaning and maintenance of the chamber. What is the yearly production of a single CSS chamber in 1 year? Give your answer in kWp/year B) VTD is a continuous process where the substrate slowly passes through the machine on a conveyor belt. The maximum width that can be passed through the machine is 1.2 m. The machine requires maintenance of 2 days after 1000 m of CdTe deposition has been deliverd. The material quality of the VTD process is equal to csS, resulting in an equal power density (Wp/m²).
