Abstract: A solar cell including at least a first layer made of a semiconductor material for absorbing photons from light radiation and releasing charge carriers, and at least one conductive layer, overlapping the first layer, adapted to allow the light radiation to enter into the solar cell towards the first layer and to collect the charge carriers released by the first layer, the solar cell where the conductive layer includes at least three overlapped layers, including a transparent intermediate metal layer, made of metal, and two transparent oxide layers, made of a conductive oxide, where the two oxide layers are an inner oxide layer and an outer oxide layer surrounding the transparent intermediate metal layer to provide a low resistance path for the electrical charges and to maximize the amount of light radiation entering the solar cell. The embodiments also include a solar cells module including said solar cell.

Abstract: A solar cell apparatus 100 and a method for forming said solar cell apparatus 100, comprising a substrate 101, a n-type transparent conductive oxide (TCO) layer 102 deposited atop said substrate 101, a p-i-n structure 200 that includes a p-type layer 103, an i-type layer 104, a n-type layer 105, a metal back layer 106 deposited atop said n-type layer 105 of the p-i-n structure 200. The n-type layer 105 comprises n-type donors 115 including phosphorus atoms. The n-type donors 115 include oxygen atoms at an atomic concentration comprised between 5% and 25% of the overall atomic composition of the n-type layer 105.

Abstract: The device (1) for supplying micronized medical salt comprises a container (2) for medical salt, having a vertical longitudinal development and a lower end portion (3) provided with a mouth of release (4) of the medical salt, a screw (20) inserted into the container and having an upper end (21) and a lower end (22) which is free, rotation members (30) of the screw mechanically connected thereto for rotating it with respect to the container, where the screw advances the medical salt downward so that the medical salt is released in a controlled manner from the mouth of release (4), the device further comprising a dispenser (50) which comprises a supply duct (51) and a ventilation member (60) which generates an air flow within the supply duct, where the mouth of release is in communication with the supply duct so as to release the medical salt directly in the air flow.

Abstract: An apparatus for carrying rope handles for paper bags to a paper bag forming station is disclosed. The rope handles are supplied to the bags at the entrance of the forming station before forming the bags. The apparatus includes a first and a second plurality of gripping devices (36) for gripping the handles (34) fed by a handle forming station. The first and second plurality of gripping devices (36) are arranged substantially side by side at the entrance of the bag forming station towards which they move. At least one pair of units (94, 98, 104) for taking the handles (34) is located at the entrance of the bag forming station. Also provided are members (70, 78, 88, 92) to control the inhibition of the gripping devices (36) and the actuation of the units (94, 98, 104) for taking the handles (34) from the gripping devices (36) so that the handles (34) are fed to the paper bag forming station.

Abstract: An immersible and disposable decorative wristwatch includes at least one watch strap that can be selectively joined at its ends and fitted over the wearer's wrist, and watch works of the quartz oscillator type, run by a battery. The watch strap is laminated and consists of a first ply made of a flexible and waterproof thermoplastic material, and a second ply placed over the first ply, which is also made of a flexible and waterproof thermoplastic material that is transparent over at least a portion of its surface. The second ply is disposed adjacent to the first ply and laminated thereto by means of thermoplastic welds which define at least one hollow hermetically sealed chamber, arranged between the ends of the set of plies so assembled. The watch works are housed within the chamber with the portion of same indicating the time facing the transparent portion of the second ply.
