Top Contact Design

The role of the top contact is to pass light into the cell while transferring the electricity out. Semiconductors, such as silicon, are orders of magnitude less conductive (more resistive) than metals so a top grid pattern is essential to reduce the series resistance on all but the smallest solar cells.

Electroplated Copper Metal Contacts on Perovskite Solar Cells

Electroplated copper contacts on small-area single-junction perovskite solar cells (PSCs) using an atomic layer deposited (ALD) Al 2 O 3 masking layer on ITO are demonstrated for the first time. The photoconversion efficiency of ≈11% after manufacturing the Cu contacts confirms that PSCs can survive the wet-chemical plating process.

Rear contact solar cells eliminate shading losses altogether by putting both contacts on the rear of the cell. By using a thin solar cell made from high quality material, electron-hole pairs generated by light that is absorbed at the front surface can still be collected at …

Microscopic Origins of Contact Deterioration During Annealing of Silicon Heterojunction Solar Cell Contacts

Over the last years, the dominating charge carrier transport barrier in silicon heterojunction (SHJ) solar cells could be boiled down to the contact of the indium–tin oxide (ITO) to the doped amorphous silicon (a-Si) layer. The formation of a parasitic oxide at this junction was hypothesized to act as a source for contact deterioration after annealing. However, no …

How a Solar Cell Works

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …
