Effect of Texture of Antireflection Layer on Photovoltaic Performance of Silicon/PEDOT:PSS Hybrid Solar Cells

The energy market has destabilized with the increased economic development of emerging countries, owing to higher global energy demands and an increase in the cost of fossil fuels[1]. In addition, the seriousness of global environmental issues, such as the emission of greenhouse gases and the frequency of abnormal weather, has grown increasingly severe[2]. To resolve these issues, solar photovoltaic systems, which are a renewable energy source, have attracted attention worldwide[3,4]. One advantage of photovoltaic power generation is that, relative to other renewable energy sources, it can be used to create electricity everywhere[5]. Recently, inorganic/organic hybrid solar cells that combine silicon (Si) with poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) have gained increasing attention as next-generation solar cells because of their simple 1Department of Electrical and Electronic Engineering, Tokyo Denki University, Tokyo, Japan 2International Center for Materials Nanoarchitectonics, National Institute for Materials Science, Ibaraki, Japan
