The allotropic forms of silicon range from a single crystalline structure to a completely unordered amorphous structure with several intermediate varieties. In addition, each of these different forms can possess several names and even more abbreviations, and often cause confusion to non-experts, especially as some materials and their application as a PV technology are of minor significa.

Solar inverters use maximum power point tracking (MPPT) to get the maximum possible power from the PV array. have a complex relationship between , temperature and total resistance that produces a non-linear output efficiency known as the I-V curve. It is the purpose of the MPPT system to sample the output of the cells and determine a resistance (load) to obtain maximum power for any given environmental conditions.

Energy conversion efficiency is measured by dividing the electrical output by the incident light power. Factors influencing output include spectral distribution, spatial distribution of power, temperature, and resistive load. standard 61215 is used to compare the performance of cells and is designed around standard (terrestrial, temperate) temperature and conditions (STC): of 1 kW/m , a spectral distribution close to solar radiation through AM () of 1.5.

Many African countries receive on average a very high number of days per year of bright sunlight, especially the dry areas, which include the arid deserts (such as the ) and the semi-desert steppes (such as the ). This gives solar power the potential to bring energy to virtually any location in Africa without the need for expensive large-scale grid-level infrastructural developments. The distribution of solar resources across Africa is fairly uniform, with more than.

Thin-film solar cells are a type of made by depositing one or more thin layers ( or TFs) of material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers () to a few microns () thick–much thinner than the used in conventional (c-Si) based solar cells, which can be up to 200 μm thick. Thin-film solar cells are commercially used in several technologies, including (.
