Interstellar photovoltaics [PDF]

Scientific Reports, 2023
AbstractThe term 'Solar Cell’ is commonly used for Photovoltaics that convert light into electrical energy. However, light can be harvested from various sources not limited to the Sun. This work considers the possibility of harvesting photons from different star types, including our closest neighbor star Proxima Centauri.

The optical performance of random and periodic textured mono crystalline silicon surfaces for photovoltaic applications

EPJ Photovoltaics, 2022
Surface textures that result in high optical yields are crucial for high efficiency photovoltaic (PV) devices. In this work three different texturing approaches are presented that result in smooth concave structures devoid of sharp features.

Nanocarbon-Based Photovoltaics [PDF]

ACS Nano, 2012
Carbon materials are excellent candidates for photovoltaic solar cells: they are Earth-abundant, possess high optical absorption, and superior thermal and photostability. Here we report on solar cells with active layers made solely of carbon nanomaterials that present the same advantages of conjugated polymer-based solar cells - namely solution ...
