Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
Solar cells (SCs) are the most ubiquitous and reliable energy generation systems for aerospace applications. Nowadays, III–V multijunction solar cells (MJSCs) represent the standard commercial technology for powering spacecraft, thanks to their high-power conversion efficiency and certified reliability/stability while operating in orbit.
The carrier transport materials The perovskite solar cell devices are made of an active layer stacked between ultrathin carrier transport materials, such as a hole transport layer (HTL) and an electron transport layer (ETL). The band alignment depends on their energy level, electron affinity, and ionization potential.
Moreover, in recent years, new SCs technologies based on Cu (In,Ga)Se 2 (CIGS) and perovskite solar cells (PSCs) have emerged as promising candidates for aerospace power systems, because of their appealing properties such as lightweightness, flexibility, cost-effective manufacturing, and exceptional radiation resistance.
The operation of solar cells is intimately related to two kinds of particles, electrons and holes, known as the charge carriers of semiconductors. For the case of electrons, this does not come as a surprise since general knowledge identifies an electric (charge) current to the continuous flow of electrons.
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
