Abstract

The invention relates to a perovskite solar cell module and a preparation method thereof. The perovskite solar cell module comprises a substrate, a transparent conductive layer, a cell active layer and a back electrode, and is characterized in that the perovskite solar cell module comprises a first channel vertically penetrating through the transparent conductive layer; a second channel verticallypassing through the cell active layer; and a third channel vertically passing through the back electrode and the cell active layer. The first channel, the second channel, the third channel and the fourth channel are prepared through mechanical cutting or laser cutting, so that the perovskite solar cell module is prepared.

Description

technical field [0001] The invention relates to a perovskite solar cell component and a preparation method thereof, in particular to a perovskite solar cell component comprising a substrate, a transparent conductive layer, a battery active layer and a back electrode and a preparation method thereof. Background technique [0002] Solar photovoltaic power generation technology is constantly developing towards the direction of low cost, high efficiency and large area production. Among them, the photoelectric conversion efficiency of perovskite solar cells has been greatly improved in several years. Perovskite solar cells are thin-film solar cells that use a new type of perovskite as the raw material and organic-inorganic hybrid materials as the absorbing layer. At present, the cell efficiency of perovskite solar cells has reached 23.7%. Due to the potential application prospects of perovskite solar cells, it has always been a hot spot for companies and research institutions i...
