Embodiment Construction

[0059] Please refer to figure 1 , which shows a schematic cross-sectional view of a photovoltaic panel according to an embodiment of the present invention. In order to replace the photoelectric conversion layer with high-cost materials to meet the requirements of harsh weather conditions, the photovoltaic panel 100 of this application basically interlayers the photoelectric conversion layer 106 between a flexible substrate 102 and an optical prism layer 110 . The purpose of using the flexible substrate 102 is to allow the photovoltaic panel 100 to be bent, so that the photovoltaic panel 100 can be applied to portable devices or home appliances. The optical prism layer 110 is used to improve the photoelectric conversion efficiency of the photovoltaic panel (such as the conversion efficiency of sunlight into electrical energy). In addition, the photovoltaic panel 100 must at least include a conductive layer 104 and a transparent conductive layer 108 to collect electric energy g...

Abstract

A photovoltaic panel includes a flexible substrate, an optical prism layer, and a photoelectric layer disposed between the plastic flexible substrate and the optical prism layer. The optical prism layer includes a transparent layer and a plurality of prisms attached to the transparent layer and disposed between the transparent layer and photoelectric layer.

Description

technical field [0001] The present invention relates to a photovoltaic panel, and in particular to a photovoltaic panel applied to portable devices and home appliances. Background technique [0002] It is known that most photovoltaic panels are expensive to manufacture. In order to meet the requirements of harsh climate conditions, the manufacturing steps of photovoltaic panels are complicated and expensive materials are used, resulting in expensive photovoltaic panels. For example, light-transmitting glass is used to block photovoltaic panels from the outside environment. A light-transmitting upper conductive layer or conductive grid lines are used to collect and output current. Multiple complex process steps (such as laser cutting and deposition process to connect photovoltaic cells to each other; tempering process to complete specific components; lamination process to encapsulate photovoltaic panels; glass substrate or other material substrate processing process) increas...
