Abstract:
The possibility of expanding the effective absorption spectrum in noncrystalline solar cells using nanoinclusions is shown in the work. The effect of deep centers of local impurities and defects on the expansion of the effective absorption spectrum in solar cells based on a new contact structure is investigated. For example, expansion into the infrared region is due to absorption in impurity centers, and absorption into the ultraviolet region is due to the thermalization process of the resulting electron-hole pairs. the main difference between the proposed structure is that the appearance of electron-hole pairs arises in a region with an integrated electrostatic field. This factor significantly reduces the influence of recombination processes.
