Abstract:
1. A method for making a photovoltaic device, comprising: monitoring a moving conductive web; determining a level of bagginess of the conductive web; and depositing a plurality of layers of the photovoltaic device on the conductive web if the level of bagginess meets a predetermined criteria; further comprising depositing the plurality of layers of the photovoltaic device on the conductive web if the level of bagginess of the conductive web is equal to or less than a predetermined level of bagginess, or rejecting the conductive web and not depositing the plurality of layers of the photovoltaic device on the conductive web if the bagginess of the conductive web is greater than the predetermined level of bagginess.
