Perovskite solar cell and method of manufacturing the same

A method of manufacturing a perovskite solar cell, the method comprising:

• a first step of forming a transparent conductive oxide layer, by a deposition process, on an electron transport layer of a stack in which a hole transport layer, a perovskite light absorption layer, and the electron transport layer are sequentially stacked;
• and
• a second step of forming a source electrode on the transparent conductive oxide layer, wherein the transparent conductive oxide layer comprises one or more of a semiconducting organic material having a pi-orbital electron, an organic material containing an element having an unshared electron pair, and an organic material having an ionic functional group.

A tandem silicon/perovskite heterojunction solar cell comprising:

• a stack in which a drain electrode, a silicon solar cell, a recombination layer, a hole transport layer, a perovskite light absorption layer, an electron transport layer, and a source electrode are sequentially stacked, wherein a transparent conductive oxide layer is formed between the source electrode and the electron transport layer, and wherein the transparent conductive oxide layer comprises one or more of a semiconducting organic material having a pi-orbital electron, an organic material containing an element having an unshared electron pair, and an organic material having an ionic functional group.
