Ultrathin Wide‐Bandgap a‐Si:H‐Based Solar Cells for Transparent Photovoltaic Applications

Herein, the fabrication of UV-blue selective transparent solar cells based on ultrathin (<30 nm) intrinsic hydrogenated amorphous silicon films (a-Si:H) as absorber and using a fully inorganic architecture is reported, metal-oxide thin carrier contacts electrical contacts. These devices present photovoltaic effect high average visible transmittance (AVT), showing their potential candidates for implementation energy harvester. Potential applications range from Building-Integrated PV to agrophotovoltaics, can also be interest ubiquitous inexpensive power source integrated in functional such low-power devices, Internet Things other sensors. Glass/FTO/ZnO/a-Si:H/MoO3/ITO device prototypes are produced. an AVT ranging 50% 69%, with conversion efficiency up 0.5% calculated AM1.5G spectrum have light utilization (LUE) values 0.25%, confirming proposed architectures development highly improved LUE.
