Introduction to Solar Cells

Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

Introduction to Orbital Mechanics and Spacecraft Attitudes for

Introduction 5 Orbiting spacecraft are subject to a variety of environments. Knowledge of the orbit is required to quantify the solar, albedo and planetary (also called outgoing longwave radiation, or OLR) fluxes. Some specific questions that might arise are: • How close (or how far) does the planet/spacecraft pass from the sun? • How close (or how far) does a spacecraft pass from a …

Design and investigation of flexible solar wing: In-plane dynamics

The flexible solar wing proposed in this study employs a scissor-like mechanism to deploy and support a large cell array. It is stowed in the payload bay during the launch phase. Once in orbit, the spacecraft will deploy and lock the structure to maintain shape. However, flexible solar wings in orbit could undergo various conditions [19 ...
