Abstract
An improved method for manufacturing solar cell tape including depositing a thin-film photovoltaic device on a flexible polymeric substrate, encapsulating the photovoltaic device with a layer of encapsulant, and applying a layer of adhesive to the substrate opposite the photovoltaic device. The improvement is characterized by selecting thickness of the substrate, layer of encapsulant and/or layer of adhesive as a function of their respective flexural moduli to locate a neutral plane of the electronic device near the photovoltaic device. Damaging stress on the photovoltaic device which may be caused when the electronic device is flexed can be reduced.
