Embodiment 1

[0057] Embodiment 1: as attached figure 1 As shown, several organic solar thin films 3 are interconnected by positive or negative photovoltaic junction boxes 11 to form organic photovoltaic units 4, and each organic photovoltaic unit 4 has a total positive terminal and a total negative terminal; especially, each organic photovoltaic All the organic solar thin films 3 in the unit 4 are connected in series through their respective photovoltaic junction boxes 11 to form one way to be connected through one general positive pole and one general negative pole.

[0058] In this embodiment, as attached Figure 5 As shown, the photovoltaic junction box 11 fixed on the back of the organic solar film 3 is embedded in the corresponding position on the molded concrete slab 2 to reserve a junction box embedding groove 10, and the organic solar film 3 is bonded to the molded concrete slab 2 by double-sided adhesive 9 outside surface. The outer surface of the molded concrete slab 2 is smoot...

Embodiment 2

[0069] Embodiment 2: A grid-connected photovoltaic system consists of a photovoltaic array composed of parallel organic photovoltaic units 4, a smart photovoltaic combiner box 5 including a DC lightning protection device and a DC ammeter, a grid-connected bidirectional inverter controller, and a power generation metering and monitoring system. Photovoltaic inverter 6 and installation accessories etc. constitute. The functions of each part are as follows:

[0070] (1) As attached figure 2 As shown, the solar battery array composed of organic photovoltaic cells 4: the solar battery array is the energy production unit of the photovoltaic system, and is composed of 100 thin-film solar concrete slabs formed by laminating the molded concrete slab 2 with the organic solar film 3 in total, wherein Every 25 thin-film solar concrete slabs are connected into a group of 5 pieces in series, and then 5 groups are connected in parallel to form an organic photovoltaic unit 4, and then 4 org...

Embodiment 3

[0088] Embodiment 3: The present invention is also applicable to photovoltaic curtain walls. A junction box embedding groove 10 is opened on the facade of the glass curtain wall, and photovoltaic junction boxes 11 are respectively installed on the backs of several organic solar thin films 3, and photovoltaic junction boxes 11 are embedded in the junction boxes. Groove 10, organic solar film 3 matches the size of the glass block and is sealed with sealant along the edge. On the back of the glass curtain wall, the positive or negative terminals connected by the photovoltaic junction box 11 are connected to each other to form organic photovoltaic units 4. Each organic photovoltaic unit 4 Each has a general positive connection and a general negative connection.

[0089] The organic solar film 3 applied to the photovoltaic curtain wall requires a certain degree of transparency. The transparent organic solar film 3 includes a front solar photovoltaic layer and a transparent conductiv...

Abstract

The invention relates to an external building vertical surface film-based organic photovoltaic system and an installation method. Photovoltaic junction boxes (11) are fixedly arranged on the back surface of an organic solar film (3), and a junction box embedding groove (10) is formed in a corresponding position on an external building vertical surface carrying structure and used for installing the photovoltaic junction box (11); outgoing wires of the adjacent photovoltaic junction boxes (11) are connected with one another to form an organic photovoltaic unit (4) which is accessed to a photovoltaic convergence box (5) and a photovoltaic inverter (6) device, and the organic photovoltaic unit (4) can be further connected to an energy storage system (7) or a 220V power grid (8). The organic photovoltaic film is ingeniously combined with a external building vertical surface, so that the conversion efficiency is higher than 12 percent under the condition of low light and high temperature, the conversion efficiency of the organic solar film (3) with light transmittance of 40 percent reaches 7.2 percent, the building characteristics can be completely maintained, a decorative function, a waterproof function, a heat preserving function and a photovoltaic power generation function are integrated, the heat radiation problem in the solar battery power generation process also can be solved, and the integration of a photovoltaic building can be realized.

Description

technical field [0001] The invention relates to the collection and utilization of solar energy technology in the decoration project of IPC international patent classification E04F buildings, especially the film-based organic photovoltaic system and installation method of the building facade. Background technique [0002] In the prior art, photovoltaic cells can convert sunlight energy into electricity through the photovoltaic effect, and components composed of photovoltaic cells can be used to make photovoltaic modules or solar panels.
