The invention relates to a sealed thin- film device (10) to an organic light emitting diode device (100) and to a solar cell device (200) comprising the sealed thin- film device. The sealed thin-film device comprises a thin-film device (20) and a barrier stack (30) for protecting the thin-film device from environmental influence. The barrier stack (30) comprises an inorganic barrier layer (34) in contact with at least one organic sealing layer (32) which comprises organic material comprising selected organic material selected to comprise a value of the Young's modulus (Eorg) remaining equal to or higher than 200 Mega- Pascal during a part of the processing of the sealed thin- film device during which the at least one organic sealing layer comprising the selected organic material has been applied. An effect of the sealed thin- film device according to the invention is that the use of the selected organic material reduces the crack occurrence and growth in the barrier stack which improves the sealing properties of the barrier stack and consequently improves the operational life-time of the thin- film device.
