Problems solved by technology

However, solar windows are often limited by standard sizes, for example, the current industry standard is 65" x 40" (i.e. approximately 1.65m x 1.02m), this limitation of current manufacturing standards means that these PV photovoltaic glass panels are required for individuals Must first be manufactured in standard sizes and then rescaled to custom designs and sizes
As a result, unnecessary waste of time, energy and material often occurs during the production of such BIPV photovoltaics

Abstract

An automated system for fabricating a solar energy device is described. The automated system comprises a computer for providing automated control of the system; and a substrate carrier and a vacuum chamber operationally coupled to the computer. The vacuum chamber comprises at least one heating element for uniformly heating the substrate; a coating head assembly comprising a vaporising chamber forsublimating a photovoltaic material to form a photovoltaic material vapour and an expansion chamber fluidly coupled to the vaporising chamber for receiving the photovoltaic material vapour; and a deposition chamber for uniformly depositing the photovoltaic material vapour on the substrate. The computer is configured to control the heating element, the vaporising chamber, and a speed of the substrate carrier so as to determine a position of the substrate in relation to the expansion chamber such that the photovoltaic material vapour is uniformly deposited on a predetermined portion of the substrate.

Description

technical field [0001] The present invention relates to methods and systems for fabricating photovoltaic modules on variable sized substrates. More specifically, the present invention relates to methods and systems for fabricating photovoltaic modules on variable-sized substrates for building-integrated photovoltaic (BIPV) applications, eg, PV-integrated windows or photovoltaic-integrated glazing. Background technique [0002] Along with solar energy, building integrated photovoltaics (BIPV) has become one of the fastest growing industries. BIPV photovoltaics include photovoltaic materials that are used to replace conventional materials in traditional building exterior structural parts, such as roofs, skylights or exterior walls. Incorporating BIPV photovoltaics into the infrastructure provides the building with additional energy, beneficially supplementing and ultimately supplying all of its energy needs. This is especially important for remote buildings that do not have ...
