A dye-sensitized solar cell comprising a first support, a first conductive layer, a porous photovoltaic layer containing a dye, a carrier transport layer and a second conductive layer stacked in this order, wherein the length of contact side of the porous photovoltaic layer closed to the first conductive layer is different from that of its confronted side of the porous photovoltaic layer. The present invention also relates to pharmaceutical compositions comprising said compounds and the use of these derivatives to modulate glucocorticoid receptor activity. The first convex portion, the trigger button, and the ports are located on a side-top of the machine body. A radio receiver and loudspeaker is provided inside the polling place. The system may further include at least one transducer affixed to the distal end region of the second tubular member. Other various embodiments of the antennas include a hybrid antenna structure wherein a metallic antenna underbody replaces the non-conductive support structure.
