Novel Electrode Structure of a Photovoltaic Cell

A new method for the electrode structure of high-efficiency photovoltaic cell by an air bridge electrode has been developed. Three types of the photovoltaic cells; a non texturing photovoltaic cell, a TMAH(Tetra methyl ammonium hydroxide)-texturing photovoltaic cell with an electrode using a screen print, a TMAH-texturing photovoltaic cell with an air bridge electrode have been processed in order to optimize the electrode structure. An efficiency of 3.62% was achieved for an air bridge electrode photovoltaic cell, which is better than the efficiency 2.24% for conventional photovoltaic cells fabricated by using a TMAH-texturing process and screen-printed electrodes. Air bridge electrodes augmented incident light by diffraction of sunlight. KCI Citation Count: 0
