Solar Cells (Photovoltaic Cells)
2021The sun releases a vast amount of energy into the solar system. The temperature at the surface of the sun is approximately 5800 K. At a point just outside the earth’s atmosphere the solar flux is about 1353 W/m2. Almost all renewable energy sources with exception to radiative and nuclear energy sources, have their energy from the sun.

Transparent ultraviolet photovoltaic cells
Optics Letters, 2016Photovoltaic cells have been fabricated from p-GaN/MgO/n-ZnO structures. The photovoltaic cells are transparent to visible light and can transform ultraviolet irradiation into electrical signals. The efficiency of the photovoltaic cells is 0.025% under simulated AM 1.5 illumination conditions, while it can reach 0.46% under UV illumination.

Tandem Photovoltaic Cells with Amorphous Silicon Cells and Organic Photovoltaic Cells
MRS Proceedings, 2011ABSTRACTWe demonstrate series-connected tandem photovoltaic cells consisting of hydrogenated amorphous silicon (a-Si:H) solar cells and polymer-based organic photovoltaic (OPV) cells. One of the limiting factors of a-Si:H solar cells is their narrow absorption spectrum as compared with that of crystalline silicon solar cells.

Thermoradiative–Photovoltaic Cells
IEEE Transactions on Electron Devices, 2019A novel model of the hybrid cells consisting of a thermoradiative (TR) cell and a photovoltaic (PV) cell is conceptually proposed, where the TR and PV cells are coupled via far-field thermal emission. Analytical formulas for the power output density and efficiency of the hybrid cells are derived.

ELECTROSPUN PHOTOVOLTAIC CELLS
Journal of Macromolecular Science, Part A, 2002Electrospinning is a simple technique to form high surface area membranes using large static electric potentials. An application, taking advantage of such a high surface area, is a dye-sensitized photovoltaic cell, wherein a chromophore molecule absorbs light before being oxidized to generate a photocurrent.
