Abstract

A photovoltaic device manufacturing method is disclosed. Methods include manufacturing a photovoltaic cell using nanoimprint technology to define individual cell units of the photovoltaic device. The methods can include providing a substrate; forming a first conductive layer over the substrate; forming first grooves in the first conductive layer using a nanoimprint and etching process; forming an absorption layer over the first conductive layer, the absorption layer filling in the first grooves; forming second grooves in the absorption layer using a nanoimprint process; forming a second conductive layer over the absorption layer, the second conductive layer filling in the second grooves; and forming third grooves in the second conductive layer and the absorption layer, thereby defining a photovoltaic cell unit.

Description

technical field [0001] The invention relates to a photovoltaic cell, in particular to the preparation of a photovoltaic cell. Background technique [0002] Photovoltaic cells, also known as solar cells, convert light energy into electricity. In order to provide a higher conversion rate, the industry continues to develop photovoltaic cells and their fabrication methods. For example, thin film photovoltaic cells have provided better conversion efficiency. Traditionally, thin-film photovoltaic devices are prepared by using laser and mechanical cutting to define, wire, and isolate photovoltaic devices to form individual connected photovoltaic cells. These methods have been found to cause low productivity and damage to the surface of the photovoltaic cell. Therefore, although the existing methods can generally achieve the desired purpose, they are not satisfactory in all aspects. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the...
