Abstract:
페로브스카이트태양전지의제조방법이개시된다. 페로브스카이트태양전지는기판상에페로브스카이트태양전지소자를형성한후 무극성용매에용해된고분자물질을포함하는고분자용액을이용하여페로브스카이트태양전지소자의외부면을피복하도록봉지층을형성함으로써형성될수 있다. 이러한제조방법에따르면, 페로브스카이트태양전지의제조과정에서페로브스카이트물질및 유기정공전달물질이손상되는것을방지하여페로브스카이트태양전지의광전효율및 수명을향상시킬수 있다.

본발명은태양전지에서안정성이향상된전자전달체및 이의제조방법에관한것이다. 특히, 본발명은최근고효율태양전지로활발히연구중인페로브스카이트태양전지에서안정성이향상된전자전달체를제공할수 있다. 본발명은기존나노입자기반전자전달체표면에조해성이큰 산화물반도체를도포하여수분을흡수하는안정화전자전달체를제조하고이를페로브스카이트태양전지에적용하여기존페로브스카이트태양전지의수분의취약한문제를극복하고장기안정성을보장하는것을목적으로한다.
Abstract:
Disclosed is a solar cell. The solar cell includes a transparent conductive layer formed on the upper part of a substrate; fine structures vertically or slantly protruded from the surface of the transparent conductive layer; an electron delivering layer covering the fine structures and formed of an electron delivering metal oxide; a light absorber attached on a pore or the surface inside the electron delivering layer; a hole transport layer covering the surface of the electron delivering layer and formed of a hole transporting material; and an electrode formed on the upper part of the hole transport layer. According to the solar cell, the thickness of a light absorbing layer can be maximized and it is possible to provide high current density and photoelectric conversion efficiency.
