摘要:
Provided are methods and systems for treating shunts on solar cell substrates. Also provided are solar cells including such substrates. A shunt detected on a substrate proximate to a metallized grid pattern is electrically disconnected from at least the bus portion of the grid, which reduces shunt's impact on performance on the solar cell. An antireflective layer may be disposed between the shunt and a portion of the grid extending over the shunt. The exposure pattern of a photoresist used to form the antireflective layer may be adjusted accordingly to achieve this result. In some embodiments, the metallized grid may be modified by adjusting the exposure pattern of a photoresist used to form this grid. The grid may be modified to avoid any contact between the grid and the shunt or to disconnect a portion of the grid contacting the shunt from the bus portion area of the grid.

The present invention allows a crystalline photovoltaic module having a super straight type structure in which a light-receiving surface side-sealing EVA layer 2, a photovoltaic cell matrix 3, a back surface side-sealing EVA layer 4 and a back surface-sealing weatherproof film 5 are laminated sequentially in this order on a light-receiving glass 1 and these components are formed into an integral piece to be reused after it has been used in the market for a long time by extending the lifetime of the photovoltaic module. The regeneration method includes peeling the back surface-sealing weatherproof film 5, laminating a new back surface side-sealing EVA layer 8 and a new back surface-sealing weatherproof film 9 in a portion in which the film has been peeled, and then curing for crosslinking the new back surface side-sealing EVA layer 8 that is laminated.

A solar cell module comprises a photovoltaic device having a flexible substrate. The photovoltaic device has a strain at least partly in the planar direction of the flexible substrate, and the strain is set not more than a critical value at which the photovoltaic device cracks. The solar cell module may further comprise a strain holding means for holding the strain. A deformable region where the photovoltaic device can be deformed when a region embracing the photovoltaic device is worked is defined so that a great variety of solar cell modules having a high reliability, also taking account of manufacture, can be designed in a good efficiency.

A method of manufacturing an integrated thin film solar battery module including a substrate, and a plurality of unit cells connected in series on the substrate, each of the unit cells having a first electrode layer, a semiconductor layer and a second electrode layer which are stacked one upon the other on the substrate. The method includes the steps of scribing the first electrode layer formed on the substrate, forming a semiconductor layer on the first electrode layer, scribing the semiconductor layer for each of the plurality of unit cells to form openings for connection to the first electrode layer, forming a second electrode layer on the semiconductor layer, scribing the second electrode layer and the semiconductor layer in the vicinity of the openings formed in the semiconductor layer, allowing an edge surface of the semiconductor layer to be exposed to the outside by removing residues of the second electrode layer and the semiconductor layer, and applying a heat treatment at 130° C. or higher after division of the second electrode layer and the semiconductor layer.
摘要:
The method and apparatus for measuring the current-voltage characteristic curve of a solar panel uses cost-effective equipment and a minimized need of optical output power. A light pulse is applied to the solar panel and the response of the solar panel to the light pulse is measured by varying the electrical load connected to the output of the solar panel. The measurement is carried out with the help of a short-duration decaying light pulse such that the falling tail of the pulse is used for such a short period that the intensity of the pulse does not have time to change essentially during the measurement.
摘要:
A method of removing any short-circuit defect existing in a photoelectric conversion device such as solar batteries having a semiconductor layer which is disposed between an upper transparent electrode and a lower electrode and which produces an electromotive force when irradiated with a light. The method comprises applying a voltage between the photoelectric conversion device and a counter electrode across an electrolytic solution containing hydrogen ions and/or hydronium ions. The electrolytic solution is an aqueous solution of an electrolyte or electrolytes selected from a group consisting of inorganic acids, organic acids, inorganic bases, organic bases and salts of metals having standard electrode potential levels which are minus relative to the standard hydrogen electrode potential and which have absolute values greater than hydrogen super voltage.
