Dye-sensitized solar cell

The present invention relates to a dye-sensitized solar cell. In the present invention, an uneven shape is formed on a contact surface of a conductive material layer with a light absorbing layer to induce an increase of a light receiving area of the corresponding light absorbing layer, wherein the conductive material layer and the light absorbing layer are installed in a substrate (e.g., a lower substrate). Accordingly, without an excessive increase in thickness, it is possible to enable light to be inputted to the light absorbing layer through various paths such as front/rear, left/right, and top/bottom by means of the uneven shape of the conductive material layer which is defined merely by an uneven groove, an uneven surface, and the like, thereby inducing the light receiving area or a light receiving amount of the light absorbing layer to be maximized in an optimal state. Thus, there is no need for a manufacturer of a solar cell to suffer various problems (e.g., serious problems such as generation of cracks, an increase in the probability of occurrence of recombination, and the like) generated due to an excessive increase in the thickness of the light absorbing layer. Also, it is possible to guide the manufacturer to effectively cope with various demands with respect to an increase in current output of a product. 본 발명은 염료감응형 태양전지에 관한 것으로, 본 발명에서는 를 강구하고, 이를 통해, 광 흡수층 측에서, 별도의 무리한 두께 증가 없이, 단지, 요철 홈, 요철 면 등에 의해 정의되는 전도성 물질층의 요철 형상을 통해, 전/후, 좌/우, 상/하의 다양한 경로로 광선을 유입 받으면서, 자신의 수광 면적 또는 수광 량을 최적의 상태로 극대화시킬 수 있도록 유도함으로써, 결국, 태양전지 생산주체 측에서, 광 흡수층의 무리한 두께 증가에 기인한 각종 문제점(예컨대, 크랙이 발생하는 심각한 문제점, 재결합 발생확률이 증가하는 심각한 문제점 등)을 전혀 겪지 않으면서도, 제품의 전류 생산량 증가에 대한 최근의 다양한 요구에 효과적으로 대처할 수 있도록 가이드 할 수 있다.
