Disclosed are a photovoltaic module, an integrated photovoltaic/photo-thermal module and a manufacturing method thereof. The photovoltaic module includes: a front glass plate (1), a first back plate (4), an adhesive layer (3) located between the front glass plate and the first back plate, and cell sheets (5) located in the adhesive layer. At least a hollow layer (2) is included between the front glass plate and the adhesive layer. Since the photovoltaic module and the integrated photovoltaic/photo-thermal module include the hollow layer, making the integrated photovoltaic/photo-thermal module itself has a partial heat insulation function without the need to add a front glass blocking plate or a hollow heat insulation layer directly in front of the light-receiving surface of the module, thereby simplifying the structure and manufacturing process of the integrated photovoltaic/photo-thermal module.

An embodiment of the present disclosure provides a manufacturing method of a solar cell module and a solar cell module. The manufacturing method of a solar cell module includes: providing a solar cell string; fabricating a back plate, a reserved hole being opened in the back plate; providing a front plate; arranging the solar cell string on the front plate; injecting an encapsulant material; and curing the encapsulant material, to obtain the solar cell module. The solar cell module is manufactured by directly curing the injected encapsulant material and no lamination process is performed, which can avoid defects such as hidden cracks of solar cells and breakage of the welding strip caused by the lamination process, which can reduce an amount of the encapsulant material used, reduce a distance between the back plate and the solar cell string and improve the energy conversion efficiency.

The invention relates to a method of producing a plate arrangement comprising two plates (1, 2) which, at least in sections, have an intermediate space (4) located between them and a constant distance (d) to one another and/or are arranged parallel to one another and between which a fusible solder material (3, 3′) is arranged. The task of setting a defined distance between the plates as accurately as possible is solved according to the invention by creating a pressure difference between the intermediate space (4) between the plates and the outer space surrounding the plates in such a way that the pressure in the outer space is higher than in the intermediate space (4) and that the temperature of the solder material (3, 3′) is at least temporarily raised above its melting temperature during the existence of the pressure difference.

Provided are a photovoltaic module, comprising a solar cell string having a plurality of solar cells arranged in sequence, adjacent solar cells being connected by solder strips, the solder strip being connected to a front surface of one solar cell and to a back surface of the other solar cell, a long-side dimension of the solar cell being within a range of 150 mm to 220 mm; two protective adhesive layers respectively covering front and back surfaces of the solar cell string, a dimensional difference between thicknesses of one protective adhesive layer and the solder strip being defined as first thickness, a ratio of the first thickness to the thickness of one protective adhesive layer being not less than 0 and not greater than 20%; a transparent plate covering the protective adhesive layer on the front surface; and a back plate covering the protective adhesive layer on the back surface.

The present disclosure provides a solar module including an encapsulating layer, solar cells embedded in the encapsulating layer, and a patterned layer formed on the encapsulating layer. The pattered layer includes at least one patterned unit having a plurality of color spots separated from one another, thereby allowing light incident on the color spots to be diffracted through adjacent gaps, so as to produce Poisson spots on the solar cells at locations corresponding to the color spots.

Solar devices and methods for producing solar devices are disclosed. In some examples, a solar device includes solar cells arranged in a shingled manner such that adjacent long edges of adjacent ones of the solar cells overlap. The adjacent long edges have a non-linear shape that has protruding portions. The solar device includes contact pads arranged in the protruding portions of the adjacent long edges such that the contact pads of the adjacent ones of the solar cells are electrically connected.

A photovoltaic module includes at least one solar cell, an encapsulant encapsulating the at least one solar cell, a frontsheet juxtaposed with the encapsulant, and backsheet juxtaposed with the encapsulant. The frontsheet includes a glass layer, a polymer layer attached to the glass layer, and an adhesive layer attaching the polymer layer to the glass layer. The backsheet includes a single-layer, moisture-resistant, fire-retardant membrane.

Disclosed herein are approaches to fabricating solar cells, solar cell strings and solar modules using roll-to-roll foil-based metallization approaches. Methods disclosed herein can comprise the steps of providing at least one solar cell wafer on a first roll unit and conveying a metal foil to the first roll unit. The metal foil can be coupled to the solar cell wafer on the first roll unit to produce a unified pairing of the metal foil and the solar cell wafer. We disclose solar energy collection devices and manufacturing methods thereof enabling reduction of manufacturing costs due to simplification of the manufacturing process by a high throughput foil metallization process.

According to embodiments provided herein, the performance of photovoltaic device can be improved by rapidly heating an absorber layer of a device in open-circuit to a high temperature for a short period of time followed by rapid quenching. The rapid heating may be accomplished by one or more pulses of high intensity electromagnetic energy. The energy may be visible light. The energy may be absorbed primarily in the absorber layer, such that the absorber layer is preferentially heated, promoting chemical reactions of dopant complexes. The dopant chemical reactions disrupt compensating defect complexes that have formed in the device, and regenerate active carriers.

A photovoltaic building material, which can safely generate electric power with solar power energy is disclosed. The photovoltaic building material can be used as building material, and can be directly installed on the fixed part of the building, such as roof, wall or decoration materials on the surface of building. The photovoltaic building material is accord with the architectural requirements of waterproof, fireproof, load-carrying ability, durability and heat-insulation. When this invention is installed on the roof, the automatic spraying device can be set up on the height of ridge, which realizes the functions of roof cleaning and cooling down by the automatic water spraying. Also, with the auxiliary device, this invention can intensify the ability to withstand strong winds for roof, and can ensure safety in the typhoon/hurricane area.
