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 …

6.0 Structures, Materials, and Mechanisms

Because mechanisms add complexity and a single point failure risk in some instances, such as attitude control or solar panel pointing, directional antenna control, or one-time sub-system deployment switches, it is important to focus on reliability strategies. Mechanisms have contributed to over 10% of reported small satellite failures (37).

Getting there will be a challenge, but they believe they can do it by carefully optimizing the composition and configuration of the PV materials. Indeed, says Lunt, by simply "stacking" their transparent solar cells, they could potentially reach an efficiency of 10% while still maintaining the ability to transmit light.
