  • The $Ag_2Te$ crystal was grown by the Bridgman method. The $Ag_2Te$ crystal was an monoclinic structure with lattice constance a = $8.1686{\AA}$, b = $9.0425{\AA}$, c = $8.0065{\AA}$. Hall effect shows a n-type conductivity in the $Ag_2Te$ crystal. The electrical resistivity was 1.080e-$3{\Omega}cm$ and electron mobility was $-5.48{\times}10^3cm^2/V{\cdot}sec$ at room temperature(RT).

  • 태양전지는 태양광에너지를 바로 전기에너지로 전환시키는 소자이다. 과거에 많이 연구되던 고품질의 단결정 소자는 높은 에너지 변환효율을 가지고 있으나 가격 경쟁력이 크게 뒤져 일반화되지 못하였다. 최근에는 다결정 태양전지의 응웅 가능성에 대한 연구가 활발히 진행되어 오고 있다. 이중 $CuInSe_2$는 여러 가지 좋은 물성을 가지고 있어서, 저가의 고효율 태양전지를 위한 광흡수층 재료로 가장 주목받고 있다. $CuInSe_2$ 화합물 박막을 제조하기 위해 단위원소를 spttering법 과 Evaporeation법을 사용하여 증착하고 전기로에서 열처리 공정을 사용하여 single-phase 화합물 $CuInSe_2$ 박막을 얻고자 하였다.

  • Process variables for manufacturing the $CuInSe_2$ thin film were established in order to clarify optimum conditions for growth of the thin film depending upon process conditions (substrate temperature, sputtering pressure, DC/RF Power), and then by changing a number of vapor deposition conditions and Annealing conditions variously, structural and electrical characteristics were measured. Thereby, optimum process variables were derived. For the manufacture of the $CuInSe_2$, Cu, In and Se were vapor-deposited in the named order. Among them, Cu and In were vapor-deposited by using the sputtering method in consideration of their adhesive force to the substrate, and the DC/RF power was controlled so that the composition of Cu and In might be 1 : 1, while the surface temperature having an effect on the quality of the thin film was changed from 100[$^{\circ}C$] to 300[$^{\circ}C$] at intervals of 50[$^{\circ}C$].
