Perovskite Solar Cell Module

Abstract

A perovskite solar cell module, comprising: a transparent substrate divided into a first unit area and a second unit area; and a first perovskite solar cell unit and a second perovskite solar cell unit, which are divided into formed on the first unit area and the second unit area on the transparent substrate and respectively including: a transparent electrode; an absorption layer formed of a perovskite material; a metal electrode into which holes flow from the absorption layer; and holes a transport layer disposed between the absorber layer and the metal electrode and transporting holes to the metal electrode, wherein the metal electrode includes a connection portion connected to the transparent electrode included in the second perovskite solar cell unit, And the first perovskite solar cell unit and the second perovskite solar cell unit are electrically connected, the hole transport layer includes an insulating part, which is arranged between the absorbing layer and the connecting part so that the absorbing layer and the connecting part are electrically connected. insulation.

Description

technical field [0001] The present invention relates to a perovskite solar cell module, in particular, to a perovskite solar cell module in which solar cell units including a material having a perovskite structure as an absorber layer are electrically connected to each other. Background technique [0002] Due to the depletion of existing fossil energy resources such as oil and coal, research and development are underway to replace existing fossil energy with safe energy, as in the case of the Fukushima nuclear power plant accident, and to reduce environmental pollution with the rise of global warming issues Of the energy sources, among them, solar energy utilizing sunlight can be used infinitely and therefore much research is being carried out in particular. [0003] A solar cell using sunlight is a device that converts light energy into electrical energy by using the photovoltaic effect (photovoltaic effect), typically having a silicon solar cell, and a commonly used solar ...

AI Technical Summary

Problems solved by technology

At this time, there is a possibility that problems such as damage or shunt (SHUNT) in the absorbing layer that may occur in the structure during the scribing process may arise.

In particular, a shunt phenomenon occurs in which electrons generated in the absorbing layer due to contact between the metal electrode and the absorbing layer move not to the transparent electrode but to the metal electrode, thereby possibly generating the perovskite The problem of reduced photoelectric conversion efficiency of mining solar cell modules
