Objective of this study is to develop new concept of solar cell based on double excitation in organic and inorganic semiconductor composite, that is similar with photosynthesis. In contrast to the conventional solar cell, the objective solar cell exhibits high electromotive forces by using excitation in organic and inorganic semiconductor. For the case of inorganic semiconductor, we found that ZnO nano tube array deposited by hydrothermal synthesis method shows large electromotive forces of 0. 5 V under irradiation of 500 W Xenon lump.On the other hand, among various organic dyes, it was found that Cuphthalocyanine and 2-amino anthraquinone shows relatively large photocurrent. However, in case of 2-amino anthraquinone is decomposed by electrolysis at 1. 0V. Therefore, the optimized dye for solar cell is Cu-phthalocyanine. Combination of ZnO and Cu-phthalocyanine electrodes shows 0. 7 V for open circuit potential and 1mA/cm2 short circuit current. The current issues is to high resistance of organic dye nd so improvement of organic dye electrode could improve the power generation property of new type solar cells. This study reveals that the concept of double excitation is used for solar cells with high efficiency.

本研究的目的是发展一种类似于光合作用的基于有机-无机半导体复合材料双激发的太阳能电池新概念。与传统太阳能电池相比，目标太阳能电池通过使用有机和无机半导体中的激发而呈现高电动势。对于无机半导体，我们发现水热法制备的氧化锌纳米管阵列具有很大的电动势，其电动势为0。另一方面，在各种有机染料中，发现铜酞菁和2-氨基蒽醌显示出相对较大的光电流。然而，在2-氨基蒽醌的情况下，在1. 0伏。因此，用于太阳能电池的最佳染料是铜酞菁。ZnO和铜酞菁电极的组合显示0。开路电位为7 V，短路电流为1 mA/cm 2。目前的问题是有机染料的高电阻和有机染料电极的改进可以提高新型太阳能电池的发电性能。这项研究表明，双激发的概念是用于高效率的太阳能电池。
