Transparent solar cells based on a-Si1-xCx:H alloys: from silicon to carbon-rich absorbers
Year: 2025
Type: article
Abstract: Amorphous silicon-based absorbers have re-emerged in recent years as a good choice for implementing highly reliable transparent photovoltaic devices. While this technology ensures long-term stability and scalability, amorphous silicon exhibits relatively high absorption in the ultraviolet and visible part of the spectrum. This work reports on the use of hydrogenated amorphous silicon-carbon (a-Si 1-x C x :H) films as a transparent absorber. By varying the carbon content, the properties of the absorber can be tuned, resulting in transparent devices with average photopic transmittance greater than 60% and a light utilization efficiency of approximately 1.3%. Additionally, the introduction of carbon enhances solar cell performance under low light irradiance, which is a typical condition in indoor photovoltaic applications.
