Description

technical field [0001] The present invention relates to a dye-sensitized photovoltaic cell, in particular to a dye-sensitized photovoltaic cell and module manufactured by a specific method. Background technique [0002] Dye-Sensitized Photovoltaic Cell (Dye-Sensitized Photovoltaic Cell), also known as Dye-Sensitized Solar Cell (DSSC), is a new type of solar cell. Batteries are much cheaper and have attracted considerable attention in recent years. As the power supply requirements for devices such as IoT sensors and mobile devices gradually emerge, the application of DSSCs that still have excellent power conversion efficiency under low light sources will become more important. [0003] In recent years, soft DSSCs have attracted great attention from battery-free IoT sensor application companies due to their light weight, flexibility, and wide range of applications. Since the unit voltage of DSSC is usually greater than or equal to 0.4V and less than or equal to 0.6V, if it i...

AI Technical Summary

Problems solved by technology

The hole runs through the entire DSSC unit and is protected by protective barriers on both sides to prevent electrolyte leakage and corrosion of conductive materials. If the protective barrier is not installed or the protective barrier is damaged, the DSSC will easily fail

[0005] The disadvantage of the method of series connection through perforation is that each DSSC unit needs to be drilled separately before filling the conductive material, and this step is time-consuming and increases the manufacturing cost of the DSSC unit

In addition, in order to prevent the conductive material used in series on each side from being corroded by the electrolyte, a protective barrier needs to be installed to protect the conductive material, and the coating and manufacturing process of the protective barrier will also increase the cost of the DSSC unit
