Introduction

Solar power generation has emerged as the predominant method of power generation for small spacecraft. In 2020, an impressive 85% of all nano satellite form factor spacecraft were equipped with solar panels and rechargeable batteries. However, the utilization of solar cells in space applications does come with its limitations.

These include diminished efficacy in deep-space applications, the inability to generate power during eclipse periods, degradation over the mission's lifespan due to aging and radiation, as well as high surface area, mass, and cost. To address these challenges, spacecraft designers are incorporating mechanical deployment mechanisms to pack more solar cells into the limited volume of SmallSats and NanoSats. Although this enhances solar cell deployment, it can also increase spacecraft design complexity, reliability, and risks.

Factors Affecting Growth

The efficacy of solar cells is influenced by the solar intensity, which varies as the inverse square of the distance from the Sun. Additionally, the projected surface area of the panels exposed to the Sun impacts the power generation and varies as a cosine of the angle between the panel and the Sun. While single-junction cells are inexpensive to manufacture, their efficiency is relatively low, typically less than 20%.

Therefore, modern spacecraft designers are increasingly favoring multi-junction solar cells made from multiple layers of light-absorbing materials. These cells efficiently convert specific wavelength regions of the solar spectrum into energy, allowing for the utilization of a wider spectrum of solar radiation.
