Abstract: A solar cell is discussed, which includes a tunneling layer on one surface of a semiconductor substrate; a first conductive type region on the tunneling layer; a second conductive type region on the tunneling layer; a first electrode and a second electrode, the first electrode connected to the first conductive type region and the second electrode connected to the second conductive type region. The tunneling layer includes a first portion and a second portion. The first portion is disposed to correspond to at least a part of the first and second conductive type regions and has a first thickness. At least a part of the second portion is disposed to correspond to a boundary portion between the first conductive type region and the second conductive type region. The second portion has a second thickness greater than the first thickness.

Abstract: A solar cell module includes: a solar cell comprising a perovskite solar cell; a first encapsulating material and a second encapsulating material for sealing the solar cell; a first protective member positioned on the first encapsulating material; a second protective member positioned on the second encapsulating material; and a third encapsulating material positioned on a side surface of the first encapsulating material and the second encapsulating material. The water vapor transmission rate (WVTR) of the third encapsulating material is less than the WVTR of the second encapsulating material, and the WVTR of the second encapsulating material is less than the WVTR of the first encapsulating material. Thus, it is possible to obtain the effects of securing the conversion efficiency of the solar cell module against degradation and securing reliability of the solar cell module.
