Herstellungsverfahren eines biegesteifen Dünnschicht-Sonnenzellen-Bandes.

摘要

An improved method for manufacturing solar cell tape (10) including depositing a thin-film photovoltaic device (5) on a flexible polymeric substrate (3), encapsulating the photovoltaic device with a layer of encapsulant (1), and applying a layer of adhesive (4) to the substrate (3) opposite the photovoltaic device. The improvement is characterized by selecting thickness (t3, t1, t4) of the substrate (3), layer of encapsulant (1) and/or layer of adhesive (4) as a function of their respective flexural moduli (E3, E1, E4) to locate a neutral plane of the integrated circuit near the photovoltaic device (5). Damaging stress on the photovoltaic device (5) which may be caused when the integrated circuit (10) is flexed can be reduced.
