    • PURPOSE: A dye-sensitized solar cell and a manufacturing method thereof are provided to increase a current value by light scattering at a porous electrode since radiated light meets a light scattering layer in all unit cells after passing a porous electrode layer including a dye attached metal oxide nano-particle, thereby enabling the manufacture of an integrated module with high photoelectric transmission efficiency. CONSTITUTION: A connecting electrode electrically connects a first unit cell and a second unit cell. An insulator between unit cells electrically insulates the first unit cell and the second unit cell. A dye-sensitized solar cell includes an array structure of alternating polarity comprised of an electrode for external connection which is respectively prepared for an upper and lower transparent substrate. The first and second unit cells include a pair of conductive transparent electrodes, a porous electrode layer, a light scattering layer, and a catalyst membrane electrode. The porous electrode layer is formed on one side of the conductive transparent electrode and includes a first metal oxide nano-particle with an average diameter of 10nm to 50nm. The light scattering layer includes a second metal oxide nano-particle in which average particle diameter is 100nm to 500nm. The catalyst membrane electrode is formed on the other side of the conductive transparent electrode.

    • 전기화학적증착법과뒤따르는열처리공정을이용하여약 10%의고효율을보이는 CuZnSn(S,Se)(CZTSSe)박막태양전지를제작하였다. 단일(one-pot) 전기화학적증착법을이용하여몰리브데넘(Mo)이증착된소다라임글래스(Soda lime glass)위에구리-아연-주석(Cu-Zn-Sn) 합금형성하였고, 이금속합금박막을황(S), 셀레늄(Se), 아르곤(Ar)이혼합된분위기에서열처리를하여밴드갭 1.13 eV의 CZTSSe 박막을형성하였다. X-선회절분석과전자분광법을통해높은결정성을가진약 2.5um 두께의박막이성공적으로형성된것을확인하였고, 원소뎁스프로파일링(depth-profiling)에서 CZTSSe 박막의수직방향으로조성/밴드갭경사가존재하는것을확인하였다. 밴드갭에너지의조절, 밴드갭경사의형성과같은밴드갭엔지니어링의결과, 최적의 CZTSSe 박막태양전지는 9.9%의광전환효율을보여주었다. 이것은지금까지보고된전기화학적증착법을이용한 CZTSSe 박막태양전지중 가장높은효율이다.
