| Resumo: | Transparent Photovoltaic (TPV) technologies represent a promising branch within photovoltaics, seeking to expand their applications by overcoming challenges related to on-site integration, especially within architectural elements related to Building Integrated Photovoltaic (BIPV), and more recently, also in the areas of Internet of Things (IoT) and Agrivoltaics. Unlike conventional approaches solely focused on efficiency, TPV introduces two additional aspects: transparency and aesthetics, which propose added challenges to the device design. This work introduces wide-bandgap inorganic-based TPV devices utilizing ultrathin intrinsic hydrogenated amorphous silicon-carbon (a-SiCx:H) as a semi transparent absorber, along with carrier-selective contacts and transparent electrodes. This innovative approach achieves a Power Conversion Efficiency (PCE) above 2.3% and an Average Photopic Transmittance (APT) of 52%, yielding a Light Utilization Efficiency (LUE) of 1.2%, comparable to best reported state of the art inorganic devices. This work holds significant relevance for the development of inorganic thin-film TPV technologies, especially those employing ultrathin absorbers. |
