Measuring method of dye sensitization nano-film solar cell I-V characteristic and conversion efficiency characteristic

Abstract

A method for measuring the I-V characteristic and conversion efficiency characteristic of a dye-sensitived solar cell comprises the following steps: 1) sensitizing the IPCE characteristic data of the solar cell with a hardware measurement dye same to the ordinary solar cell IPCE measurement system: regulating a mercury lamp and the like to emit to the monochromator and keeping the wavelength scale of the monochromator consistent with that of the mercury lamp; 2) introducing the light of the mercury lamp into the monochromator with a mode of parallel emitting, connecting the standard reference batteries to two ends of the ammeter; 3) measuring the current signal of the reference battery under the illumination of 200nm homogeneous light, wherein the range of the measurement wavelength is 200nm-1100nm; 4) changing the dye-sensitived solar cell S1, and collecting data under same condition for calculating; and 5) measuring the I-V characteristic data of the dye-sensitived solar cell S1: regulating an analog light source, and adopting a balance bridge for compensating the circuit; regulating the constant pressure source, measuring the current flowing over the sample under the bias voltages of different scanning velocities, and obtaining the I-V characteristic.

Description

technical field [0001] The invention relates to the field of application and testing of semiconductor materials, in particular to a method for testing the conversion efficiency and IPCE characteristics of a dye-sensitized nano-film solar cell. Background technique [0002] Energy issues are related to global sustainable development and have become a key factor restricting social development. In 1991, the laboratory of Professor M.Gratzel of the Ecole Polytechnique de Lausanne, Switzerland reported the research results of a new dye-sensitized nano-thin film solar cell (Dye-sensitized Solar Cell referred to as DSSC), which received widespread attention and attention internationally. Compared with the expensive production cost and complicated preparation process of silicon solar cells that currently dominate the market, the most attractive feature of dye-sensitized solar cells is its cheap raw materials and relatively simple manufacturing process, and its performance is stable,...
