The concentrating solar cell module panel, according to the present invention, comprises: a frame comprising side plates and a bottom plate; carriers which comprise solar cells and are provided on top of the bottom plate with a predetermined distance therebetween; and a lens plate, which is provided on top of the frame, for concentrating incidented light on each of the solar cells, wherein the side plates comprise a horizontal plate and a vertical plate, which is longer than the horizontal plate, wherein a plurality of ribs can be protrudingly formed on the vertical plate so as to enhance the stiffness. As a result, the concentrating solar cell module panel is self-provided with the stiffness by forming the plurality of ribs on the vertical plate, which comprises the side surface of the frame and which has a long length, thereby minimizing a support structure which may be required separately.

Abstract
The present invention relates to a scaffold assembly for in vitro expansion of haematopoietic stem cells or precursor cells, and to a perfusion bioreactor and bioreaction system for in vitro expansion of haematopoietic stem cells or precursor cells using the scaffold assembly. The scaffold assembly and the perfusion reactor using same of the present invention use materials having biocompatibility, chemical compatibility and mechanical compatibility, and comprise nanosheets and a scaffold providing a three dimensional environment for cell growth by means of rapid prototyping, and thus not only is there structural similarity to an osteoblastic niche but also the cells immobilized on the scaffold are not washed away and, at the same time, it is possible to percussion tap to a constant magnitude by means of a pump, and the cells immobilized on the scaffold are exposed to a constant stimulus such that an optimal environment similar to an in vivo environment is provided for the in vitro growth of the haematopoietic stem cells or precursor cells.
