| Outline of Final Research Achievements |
Indium-tin-oxide (ITO) monolith with high electric conductivity and light transmittance was successfully prepared. We attempted that this structural material was used as a TCO for an inorganic-thin-film solar cell. Photo sintering / melting process of semiconductor layers such as n-type ZnO and p-type Cu2O was carried out using a focused-laser irradiation (wavelength 405 nm), in order to suppress formation of pinhole in the semiconductor layers. The laser irradiation on a ZnO thin film induced improvement of the crystallinity and electric conductivity via photo-sintering process. Furthermore micropattering on ZnO thin film was successfully prepared by this laser-irradiation process.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で得られた光透過性の導電モノリス多孔体は、太陽電池の集電体のみならずガスセンサー電極などの電子デバイスへの応用も期待できる。さらに、レーザーを用いた焼結・溶融システムでは、レーザーを走査することで任意のパターンを酸化物半導体上に刻印できることから、光リソグラフィーに代わる固体基板上のマイクロパターニングプロセスとして利用できる。
