Double-sided crystalline silicon photovoltaic light-transmitting window, manufacturing method and curtain system

Abstract

The invention discloses a double-sided crystalline silicon photovoltaic light-transmitting window, a manufacturing method and a curtain system.The double-sided crystalline silicon photovoltaic light-transmitting window comprises a first light-transmitting layer, a battery piece layer and a second light-transmitting layer, the battery piece layer is arranged between the first light-transmitting layer and the second light-transmitting layer in a clamped mode, the battery piece layer comprises a plurality of battery piece strings, and the battery piece strings are connected with the first light-transmitting layer and the second light-transmitting layer in a clamped mode. Each battery piece string comprises a plurality of battery pieces, the battery pieces are arranged at intervals and are connected through connecting pieces, the battery piece strings are arranged at intervals and are mutually connected through bus bars, and the battery pieces are crystal silicon double-sided battery pieces. The device has the advantages of being simple in structure, good in light transmission, high in power generation efficiency, low in cost and the like.

Description

technical field [0001] The invention mainly relates to the field of photovoltaic technology, in particular to a double-sided crystalline silicon photovoltaic light-transmitting window, a manufacturing method and a curtain system. Background technique [0002] Before the implementation of bifacial modules, BI PV had already started the production of various products, which led to the failure to design the feasibility of power generation on the back of the concept, and the corresponding lack of suitable reflective light sources, so the mainstream product at that time was single-sided solar cells. . [0003] In addition, the common BI PV products with light transmittance require a certain light transmittance for daily lighting needs, which can affect people’s lives because of the consideration of all power generation, so the light transmittance needs to be greater than 50%. Photovoltaic modules made of slices reduce the number of strings or increase huge intervals for light tr...

Problems solved by technology

The windows made of crystalline silicon solar cells using the encapsulation and typesetting process generate electricity, and at the same time use the mechanical structure to adjust the overall angle of the window. The arrangement of the internal cells is a conventional encapsulation process. Or when the windows need to be closed, a dark room will be formed indoors
