A photovoltaic device which includes: a) a substrate based on a crystalline semi-conductor material; b) a first electrode which includes at least one heterojunction made on one face, referred to as the rear face, of the substrate, where this heterojunction includes a layer based on a doped amorphous semi-conductor material; and c) a second electrode.

Display panel comprising two plates leaving between them a sealed space that is filled with a discharge gas and is partitioned into discharge cells bounded between these plates by barrier ribs made of a mineral material comprising a mineral binder based on a hydraulic binder, and a mineral filler. By using a hydraulic binder instead of a glassy mineral binder, the display panels may be manufactured at lower temperature.

Method for producing doped regions on the rear face of a photovoltaic cell. A doping paste with a first type of conductivity is deposited on a rear face of a semiconductor-based substrate according to a pattern consistent with the desired distribution of regions doped with the first type of conductivity. Then, an oxide layer is deposited at least on the portions of the rear face of the substrate not covered with the doping paste. Finally, an annealing of the substrate diffuses the doping agents in the substrate and forms doped regions under the doping paste.

The encapsulation lid comprises at least two glass layers of different compositions, a first layer called the bottom layer, which is continuous, and at least a second layer, which is discontinuous and designed so as to define cavities or anfractuosities in this lid. Preferably, the glass layers other than the first layer are preferably formed from low-melting-point frits, thereby allowing such lids to be manufactured economically, without recourse to glass machining.

Tile comprising a substrate coated with at least one array of electrodes which is itself coated with an array of barrier ribs made of a mineral material, the porosity of which is greater than 25%, comprising a porous base underlayer which is inserted between the array of electrodes and the array of barrier ribs and which is made of a mineral material, the porosity of which is greater than 25%. Reinforced porous barrier ribs are obtained; advantageously, this tile does not include a specific dielectric layer; the number of manufacturing steps is limited and the tile can be manufactured entirely at low temperature.

Process comprising the following steps: a) deposition of a green layer based on 0.1% of an organic binder, on a mineral filler and on 0.1% to 13% of a mineral binder; b) formation of the barriers by spraying an abrasive material onto a mask applied against this layer, and then removal of the mask; c) deposition of a phosphor-based green layer; d) baking of the two layers, preferably simultaneously. By virtue of the limited amount of organic binder, the abrasion rate is high; if this content is at least 2%, deterioration of the green barriers is avoided.

Process for manufacturing barriers for a plasma display panel

A plasma panel including two plates having a sealed space between them is disclosed. The sealed space is filled with discharge gas and is divided into discharge cells that are bounded between these plates by barrier ribs forming an array. The barrier rib portion that separates any two adjacent cells of the same column includes a cavity that is made in the thickness of that rib, and a notch that brings these two cells into communication with each other through the cavity. Such an arrangement makes it easier to apply the phosphors on the walls of the cells, while at the same time eliminating any risk of optical crosstalk.
