Embodiment Construction

[0015] As shown in the accompanying drawings, a partially transparent photovoltaic template 3, preferably a thin-film building-integrated photovoltaic template, such as a photovoltaic template based on amorphous silicon, includes: an outer glass 1; a photovoltaic cell 8, including a semiconductor photoelectric conversion layers and conductive electrodes; there is also a back supporting glass plate 11. The light transmittance of the photovoltaic template is greater than 5%, and there is an interlayer 57 between it and the second layer of glass 21 . The transparent glass balls 55 (glass beads) are sparsely distributed between the photovoltaic template 3 and the second layer of glass 21, so that the distance between the glass plate 11 and the glass plate 21 can be maintained uniformly not exceeding 6 mm. In order to make the space 57 a vacuum and keep it in a vacuum state, the photovoltaic template 3 and the glass sheet 21 are connected together, and a vacuum seal 44 is formed at...

Abstract

The invention discloses a partially transparent photovoltaic window, which comprises a membrane silicon photovoltaic template arranged on a glass substrate. The photovoltaic template is separated from another glass substrate by a vacuum space; a sealed energy conservation structure with high thermal insulation is formed by the two glass plates; the structure also has the function of a solar cell. The partially transparent photovoltaic window is very suitable for building integrated photovoltaic (BIPV) application.

Description

technical field [0001] The invention belongs to the field of environment-friendly building materials, in particular to solar photovoltaic building materials with energy-saving effects. Background technique [0002] Photovoltaic (PV) systems are rapidly expanding their market in energy and industrial technology development due to the increasing demand for clean, safe, sustainable and reliable energy. Photovoltaic templates can replace some building components, which can partially offset the additional cost of installing photovoltaic equipment on building walls, roofs and windows. Building Integrated Photovoltaics (BIPV) also makes it easy to use electricity that can be independent of the grid. Hydrogenated amorphous silicon (a-Si) films, and related hydrogenated silicon film alloys with various light energy band gaps, including nanocrystalline silicon, are suitable for making various light-absorbing materials with different predetermined thicknesses, and have become commerci...
