Abstract
In this paper we discuss the emerging applications of photovoltaics for laser-based optical wireless power transfer. In particular, we focus on how key factors impact the design of the system, including wavelength, power range, operating temperature and environment and their impact on the choice of laser and photovoltaic cells. Two examples are considered: the first using bespoke InP-based photovoltaics targeting 1550 nm operation for eye-safe terrestrial applications, and the second concerning the use of visible and near-IR laser illumination of solar cells for satellites in low Earth orbit. The challenges and opportunities associated with each application will be discussed.
