Flexible photovoltaic battery and method of manufacturing the same

Abstract

The invention belongs to the photovoltaic cell technology field, in particular provides a flexible photovoltaic cell and the manufacturing method thereof. The flexible photovoltaic cell comprises an euphotic outer sealing layer, at least one flaky flexible electrode layer and one flaky flexible counter electrode layer which are arranged in an inner cavity of the outer layer, and dielectric which is arranged between the electrode and the counter electrode; wherein, one surface of each electrode layeris bordered upon or is attached with the inner wall of the outer layer, the place where the outer sealing layer and the electrode is bordered upon or is attached with is euphotic , and simultaneously the electrode outlet lines of each electrode layer are connected parallelly; one surface of the counter electrode is adjacent to the electrode, the other surface is adjacent to the inner wall of the outer sealing layer, or one surface is adjacent to one of the electrode layers, and the other surface is adjacent to the other electrode layer. The flaky flexible electrode which is adopted by the flexible photovoltaic cell can improve the electrical conductivity of the electrode and the photoelectric transformation rate of the cell, and is suitable for continuous manufacturing of the cell in a large area to reduce the production cost .
