摘要:

在多铁性BiFeO 3薄膜中观察到的体光伏效应引起了人们对光伏应用的光铁电材料的新兴趣。通过使用窄带隙铁电体增加吸收,已经取得了巨大的进步,以提高光铁电体的功率转换效率(高达8.1%)。其他策略,因为它是更有效地利用铁电内部电场,正在进行中。此外,作为副产品,光致伸缩也取得了一些进展,这是光致变形现象。在这里,我们回顾正在进行的和有前途的路线,以提高铁电体的光响应。

英文摘要:

Giant photovoltaic effect due to bulk photovoltaic effect observed in multiferroic BiFeO3 thin films has triggered a renewed interest on photoferroelectric materials for photovoltaic applications. Tremendous advance has been done to improve power conversion efficiency (up to up to 8.1%) in photoferroelectrics via absorption increase using narrow bandgap ferroelectrics. Other strategies, as it is the more efficient use of ferroelectric internal electric field, are ongoing. Moreover, as a by-product, several progress have been also achieved on photostriction that is the photo-induced deformation phenomenon. Here, we review ongoing and promising routes to improve ferroelectrics photoresponse.
