Abstract

The invention provides a laboratory maximal power point tracking test system for a perovskite solar cell. The system comprises an MCU, an I / V conversion circuit and a host computer; the MCU is connected with the I / V conversion circuit via a D / A conversion circuit and an A / D conversion circuit; the MCU communicates with the host computer; the I / V conversion circuit applies a voltage output by the D / A conversion circuit to the two ends of the perovskite solar cell, and converts an output current of the perovskite solar cell into a corresponding voltage signal; the A / D conversion circuit collectsa voltage signal output by the I / V conversion circuit; and the host computer processes the voltage signals of the D / A conversion circuit and the A / D conversion circuit to obtain voltage and current information of the two ends of the perovskite solar cell to be tested. Thus, milliwatt level maximal power point of the perovskite solar cell can be tracked and tested effectively in a lab.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a maximum power point tracking testing system of a laboratory perovskite solar cell. Background technique [0002] Perovskite solar cells are a new type of thin-film solar cells. After less than ten years of development, the photoelectric conversion efficiency of perovskite solar cells has reached 23.3%. Perovskite solar cells are prepared by solution methods, with low processing costs; at the same time, the photoelectric conversion efficiency is high, which is comparable to that of monocrystalline silicon solar cells. Therefore, perovskite solar cells have excellent commercial application prospects. [0003] Under the conditions of forward scanning (scanning from short-circuit voltage to open-circuit voltage) and reverse scanning (scanning from open-circuit voltage to short-circuit voltage) of perovskite solar cells, the obtained I / V curves (ie, current / voltage curves) do not ...
