Solar generator panel and an associated satellite
A solar generator panel comprising a plane array of strings of photovoltaic cells disposed side by side. According to the invention, the cells have cropped corners suitable for generating free spaces in the interstices between the cropped corners. It is then possible to place openings in those spaces for passing cables and/or for receiving damper blocks. The invention is particularly applicable to solar panels for satellites.
1. A solar generator panel comprising an array ( 100 ) of strings ( 4 ; 1 a - 8 a ; 1 b - 8 b ) of photovoltaic cells ( 1 ) disposed side by side and substantially forming a grid on a “front”, first face of the panel, said cells being electrically interconnected to form a plurality of independent strings ( 4 ), each string being made up of cells connected in series in pairs forming rows ( 70 ) of mutually parallel cells, two successive rows in a string being electrically interconnected at their ends via connection means ( 51 ) that, from a connection to one of said two successive rows passes through the panel via a first opening ( 61 ) and that are laid on a rear face of said panel and that subsequently pass back through the panel via another first opening to connect to a second of said two rows, each string comprising positive terminals (+) and negative terminals (-), said positive and negative terminals being distributed along each string and over the structure of the panel so that the positive terminals are remote from the negative terminals so as to reduce the risk of an electric arc appearing between two terminals, each end cell ( 1 a , 8 a , 1 b , 8 b ) of a string being connected to at least one electrical energy collector cable ( 52 ) passing via at least one respective opening for bringing together collector cables and referred to as a “second” opening ( 62 ), the panel being characterized in that the cells are square or rectangular in area and are cropped at their four corners ( 30 ), the arrangement of the cells having cropped corners in the form of a grid causing small free spaces ( 7 ′) to appear in the interstices between the cropped corners of adjacent cells, in which spaces there are created the first openings and the second openings for bringing together the collector cables, which cables are directed thereto.
2. A panel according to claim 1 , characterized in that at least one inter-panel damping block is disposed in at least one of said free spaces in the interstices between the cropped corners of adjacent cells.
3. A panel according to claim 1 , in which the cells are fabricated using a method of cutting a Ge wafer.
4. A panel according to claim 1 , in which the electrical connections between two successive adjacent cells in any one string are made at the rear face of one of the cells close to at least one of its cropped corners.
5. A satellite including a solar generator panel according to claim 1 .
