Abstract:
A buffer layer for protecting an organic layer during high-energy deposition of an electrically conductive layer is disclosed. Buffer layers in accordance with the present invention are particularly well suited for use in perovskite-based single-junction solar cells and double-junction solar cell structures that include at least one perovskite-based absorbing layer. In some embodiments, the buffer layer comprises a layer of oxide-based nanoparticles that is formed using solution-state processing, in which a solution comprising the nanoparticles and a volatile solvent is spin coated onto a structure that includes the organic layer. The solvent is subsequently removed in a low-temperature process that does not degrade the organic layer.

Claim (Index 17):
The method of  claim 15  wherein the first buffer layer is formed by operations including:\n providing a first solution comprising a solvent and the first plurality of nanoparticles, wherein the nanoparticles of the first plurality thereof comprise a wide bandgap oxide; \n distributing the first solution to form a nascent first buffer layer; and \n enabling the removal of the solvent from the first solution, wherein the solvent is removed while the temperature of the optoelectronic device remains less than or equal to 200\u00b0 C.
