Description

Semi-penetrating perovskite solar cell module and laminated solar cell module Technical Field The invention relates to a semi-penetrating perovskite solar cell module and a laminated solar cell module. Background In recent years, the global climate temperature is abnormal due to environmental pollution, so the problem of continuously clean energy demand is rapidly paid attention to all countries worldwide. The solar energy is certainly the supply source of the maximum carbon-free energy, and the solar cell is a photoelectric conversion element capable of directly converting solar light energy into electric energy. The laminated solar cell module combining the semi-penetrating perovskite solar cell and the silicon crystal solar cell can improve the power generation efficiency, effectively reduce the land area use requirement and the power generation homogenization cost (Levelized Cost of Electricity, LCOE), and is beneficial to reducing the area requirement of a solar Photovoltaic (PV) device and the promotion of policies. However, such semi-transparent perovskite solar cells typically use a transparent conductive layer instead of the conventional metal back electrode. The semi-penetrating perovskite solar cell has large transverse conduction loss due to poor conductivity of the transparent conductive back electrode, and the efficiency of the whole laminated solar cell module is poor. Disclosure of Invention According to an embodiment of the present invention, a semi-permeable perovskite solar cell module includes a plurality of semi-permeable perovskite solar cells. Each of the semi-penetrating perovskite solar cells includes a transparent cathode, an electron transport layer, an absorption layer, a hole transport layer, a buffer layer, and a transparent anode, which are sequentially stacked. There is an overlap region between the transparent anode of at least one semi-permeable perovskite solar cell and the transparent cathode of an adjacent semi-permeable perovskite solar cell. The buffer layer extends over the transparent cathode in the overlap region. The semi-penetrating perovskite solar cell module further comprises a metal pattern layer, wherein the metal pattern layer is positioned between the buffer layer and the transparent cathode in the overlapped area so as to connect the transparent anode of at least one semi-penetrating perovskite solar cell with the transparent cathode of the adjacent semi-penetrating perovskite solar cell in series. According to another embodiment of the present invention, a stacked solar cell module includes the above-described semi-permeable perovskite solar cell module and a solar cell module. The solar cell module is arranged below the semi-penetrating perovskite solar cell module. Based on the above, the invention utilizes the metal pattern layer arranged between every two adjacent semi-penetrating perovskite solar cells to promote the transverse transmission of current. And the metal pattern layer is formed between the buffer layer and the transparent cathode, so that peeling between layers can be prevented in terms of structure and contact of the metal pattern layer to the lowermost transparent cathode is ensured. Therefore, the metal pattern layer in the semi-penetrating perovskite solar cell module can reduce the transverse conduction loss and improve the vertical transmission of current.
