A solar cell and photovoltaic module

Abstract

The utility model discloses a solar cell and photovoltaic module relates to photovoltaic technical field to solve the interconnection point position of electrode and welding band, when the pulling force value of outside applied to welding band reaches certain level, obvious delamination between electron transport layer and buffer layer happens, and the quality problem of solar cell is affected. The solar cell includes the semiconductor base, hole transport layer, perovskite layer and electron transport layer that are sequentially laminated, and the first surface of the one side of electron transport layer far away from perovskite layer. The solar cell further includes: the buffer layer is formed on the partial area of the first surface of electron transport layer, the connecting layer is formed on the remaining area of the first surface of electron transport layer, the first transparent conductive layer is formed on the connecting layer and the buffer layer, multiple electrodes are formed on the first transparent conductive layer, and wherein, the connecting layer includes the second transparent conductive layer and / or the antireflection layer.
