    • A solar cell including a first electrode, a second electrode arranged opposite to the first electrode, an electron transport layer arranged between the first electrode and the second electrode, a dye layer D which is in contact with the electron transport layer, a hole transport layer arranged between the electron transport layer and the second electrode and being in contact with the dye layer D, and a barrier layer, and these elements are provided on a substrate. The barrier layer prevents or suppresses short-circuit between the first electrode and the hole transport layer. The porosity of the barrier layer is made smaller than that of the electron transport layer. The barrier layer is formed into a film-like shape and arranged between the first electrode and the electron transport layer. The solar cell can accomplish excellent photoelectric conversion efficiency by the provision of such a barrier layer.
    • 一种太阳能电池,包括第一电极,与第一电极相对布置的第二电极,布置在第一电极和第二电极之间的电子传输层,与电子传输层接触的染料层D,空穴传输层 布置在电子传输层和第二电极之间并且与染料层D接触,并且阻挡层,并且这些元件设置在基板上。 阻挡层防止或抑制第一电极和空穴传输层之间的短路。 阻挡层的孔隙率比电子传输层的孔隙度小。 阻挡层形成为膜状,并配置在第一电极和电子输送层之间。 太阳能电池可以通过设置这样的阻挡层来实现优异的光电转换效率。
