Solar cell and method of manufacturing the same

摘要

Provided are a solar cell and a method of manufacturing the same. The method includes: preparing a bottom substrate including sequentially stacked first and second portions, each of the first and second portions including a plurality of grains, wherein the maximum grain size of the second portion is less than the minimum grains size of the first portion; exposing the first portion of the bottom substrate by removing the second portion of the bottom substrate; and forming a photovoltaic conversion layer on the first portion of the bottom substrate.

1. A solar cell comprising:
a bottom substrate formed by preparing a substrate including sequentially-stacked first and second portions having respectively different grain sizes, and removing the second portion to expose a top surface of the first portion, the exposed top surface of the second portion are active surface of the bottom substrate; a top substrate having one surface facing the active surface of the bottom substrate; and a photovoltaic conversion layer between the bottom substrate and the top substrate; wherein the photovoltaic conversion layer comprises: a semiconductor electrode layer disposed on the active surface of the bottom substrate and including electrode dots; a dye layer adsorbed on the surfaces of the electrode dots; and an electrolyte filling between the bottom substrate and the top substrate.
