6 FAQs about [The use of edge pressure of photovoltaic thin film modules]

What is a thin film PV module?

An additional layer of EVA adheres the back sheet to the cells. The lamination process is a batch type manufacturing process which requires large capital expenditure. Thin film PV modules use a similar lamination process, with the addition of an edge seal to prevent or minimize moisture ingress (Strevel et al., 2013).

Can a PIB-based edge seal prevent moisture from contacting photovoltaic components?

To prevent moisture from contacting photovoltaic components, impermeable frontsheets and backsheets are used with a polyisobutylene (PIB)-based edge seal material around the perimeter. Here, we evaluate the ability of a PIB-based edge seal using a molecular sieve desiccant to keep moisture out for the expected module lifetime.

What is thin film PV?

Thin Film PV products have been introduced already in the 80ies based on amorphous Si solar cells and modules. The efficiency of these modules was in the low range of about 3% (stabilized module efficiency) and the application was mainly for consumer products.

Can edge seal materials be used in photovoltaic applications?

Here, using a Ca film deposited on a glass substrate, we demonstrate the evaluation of edge seal materials in a manner that effectively duplicates their use in a photovoltaic application and compare the results with standard methods for measuring water vapor transport.

Why should we encapsulate thin film PV modules?

Since the lamination process is a well-established technology, lamination in the thin film PV module is also primarily used to reduce the overheard research cost. This creates a void for an innovative technology to encapsulate thin film PV modules.

What are thin films in photovoltaics?

1. Introduction Thin Films in Photovoltaics is much more than only Thin Film PV: each technology within our exciting industry is already using or will introduce various Thin Films in order to decrease cost and increase efficiency, whether it is the well known crystalline silicon wafer based, the large area Thin Film products or future new concepts.
