Abstract:
The present invention relates to a method and apparatus for controlling power allocation of a fuel cell-battery hybrid system. A mode switching output value, which is a reference for switching of power supply status and power allocation, is set within a range below a maximum power value of a motor supplied with a constant voltage from the fuel cell and/or the battery. A requested output value is extracted in real time. The mode switching output value is compared with the requested output value. When the requested output value is less than the mode switching output value, a fuel cell converter is operated, and an operation of a battery converter is stopped. When the requested output value is equal to or greater than the mode switching output value, both the fuel cell converter and the battery converter are simultaneously operated in a predetermined output ratio.

PROBLEM TO BE SOLVED: To provide an organic solar cell and a method of manufacturing the same. SOLUTION: The method of manufacturing an organic solar cell includes forming nano patterns on a photoactive layer of the organic solar cell using a nanoimprinting process, and applying a cathode electrode material on the photoactive layer having the nano patterns so that the cathode electrode material infiltrates the nano patterns of the photoactive layer to increase electron conductivity, thus providing an efficient electron transfer pathway. The organic solar cell is manufactured through this method. The method of manufacturing the organic solar cell reduces loss of photocurrent occurring as a result of aggregation of an electron acceptor material and improves molecular orientation of an electron donor material in the nanoimprinting process, resulting not only to provide a high efficiency organic solar cell, but also to provide an organic solar cell having a high efficiency at low cost through a simple manufacturing process. The method is thereby applied to organic solar cell fabrication which uses an environmentally friendly and recyclable energy source. COPYRIGHT: (C)2010,JPO&INPIT
