Abstract

A solar cell (100) is provided. The solar cell includes a first electrode (102), a second electrode (106), and a photoelectric conversion layer (108), disposed between the first electrode and the second electrode. The solar cell further includes an ionizable charged film (104) disposed on one of the outermost surface (102a) of the first electrode (102), and another ionizable charged film (not shown) can also be disposed on the outermost surface of the second electrode (106).

Description

technical field [0001] The present invention relates to a solar cell technology, and in particular to a solar cell and a solar cell component. Background technique [0002] Although the theoretical efficiency of solar cells is high, the actual power generation efficiency is not. There are many factors that affect the efficiency, such as the series and parallel resistance of the solar cell itself, or the shading effect of the solar cell electrodes on the sunlight, or the loss of reflected light that is not effectively captured, and so on. [0003] The recombination of electrons and holes inside the solar cell is another important factor affecting the efficiency. Absorption of incident photons with energy higher than the band gap of the solar cell generates electron-hole pairs, and then the action of the electric field present at the p-n junction of the solar cell separates these carriers. The photogenerated minority carriers (ie, electrons or holes in electron-hole pairs) w...
