Latest Patents

Dalal holds a patent for a "Thin-film crystalline silicon solar cell using a nanoimprinted photonic-plasmonic back-reflector structure." This invention discloses embodiments of a thin-film photovoltaic technology that includes a single-junction crystalline silicon solar cell. The design features a photonic-plasmonic back-reflector structure, which is crucial for lightweight and flexible energy conversion applications. The back-reflector enables high absorption for long-wavelength and near-infrared photons through diffraction and light concentration, achieved by periodic texturing of the bottom-contact layer via nanoimprint lithography. The solar cell is implemented in a heterojunction design with amorphous silicon, utilizing plasma enhanced chemical vapor deposition (PECVD) for all device layers. The integration of crystalline and amorphous silicon is accomplished through excimer laser crystallization, allowing for a monolithic process that enhances the efficiency of the solar cell.
