Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers (nm) to a few microns (μm) thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick. Thi…

Solar Photovoltaic Cell Basics

When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the "semi" means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.

What Is a Substrate?

Microchip and solar cell designs utilize multiple horizontal layers, with a typical microchip as of 2011 having several functional substrates, or foundations for layers above them. The semiconductor material starts with a device layer of transistors, which is topped by an interconnect layer to a device layer above it.

Substrate Configuration

Unlike silicon-based solar cells, thin-film solar cells have two typical configurations: substrate and superstrate configurations (cf. Fig. S1). In a substrate configuration, the layers are deposited with a bottom-up approach, i.e., deposition starts with the back contact and ends with the top transparent electrode (TE) layer, which is on the light-exposed side.
