考纳斯科技大学（KTU）有机化学实验室的研究人员已开发出可为目前正在使用的混合型太阳能电池提供更廉价选择的材料。由KTU的化学家团队创造的半导体的效率在瑞士洛桑联邦技术研究所被确认。
"The material created by us is considerably cheaper and the process of its synthesis is less complicated than that of the currently used analogue material. Also, both materials have very similar efficiency of converting solar energy into electricity. That means that our semiconductors have similar characteristics to the known alternatives, but are much cheaper," says professor Vytautas Getautis, head of the chemistry research group responsible for the discovery.
The solar cells containing organic semiconductors created at KTU were constructed and tested by physicists at Lausanne. The tests revealed outstanding results: the effectivity of the cells' converting solar energy into electricity was 16.9 percent. There are only a few organic semiconductors in the world affording such a high solar cell efficiency.
Prof Getautis says that the material created at KTU will be used in the construction of future solar cells: almost all solar cells are made from inorganic semiconductors. Hybrid, semi-organic solar cells are still being developed and perfected at the research centres all over the world.
KTU and Swiss Federal Institute of Technology Lausanne registered the invention at the European Patent Office.
The work was featured in Angewandte Chemie International Edition.
