Abstract

A dye-sensitized solar cell comprises at least a first photovoltaic conversion unit and a second photovoltaic conversion unit. The first photovoltaic conversion unit further comprises a first photo-anode and a first counter electrode, the second photovoltaic conversion unit further comprises a second photo-anode and a second counter electrode, the first photo-anode and the second counter electrode are in electric connection respectively through a first electrical lead arranged on the first photo-anode and a second electrical lead arranged on the second counter electrode to form a series circuit, the first electrical lead and the second electrical lead of the series circuit are vertically overlapped, and the transverse length of the overlapped position is smaller than the length of the longer one of the first electrical lead and the second electrical lead. In the industrialized production process, the dye-sensitized solar cell largely reduces the materials used by the electrical leads, lengthens a diffusion path of an electrolyte solution, reduces the possibility that metal gates are corroded, and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a dye-sensitized solar cell. Background technique [0002] A solar cell is a device that directly converts solar energy into electrical energy, and it is based on the photovoltaic effect. As early as 1839, the French electrochemist Becquerel discovered the photovoltaic effect for the first time in a chemical reaction. A metal electrode coated with copper oxide or silver halide was immersed in a dilute electrolyte solution, and an electric current was generated under the condition of light. In 1873, SmithW also observed the photovoltaic effect in a system of solid selenium (Se). In 1876, AdamsWG and DayRE subsequently developed the Se / CuO photocell. Reports about silicon photovoltaic cells appeared in 1941, and the earliest solar cells were monocrystalline silicon solar cells. In 1954, Chapin et al. of Bell Labs made silicon-based p-n junction solar cells for the first tim...
