Chip-scale solar thermal electrical power generation
Photovoltaic (PV) cells can directly convert solar energy into electrical power with a maximum efficiency of around 30%, and most of the solar energy is not only lost as heat but also contributes to deteriorating the performance. 8–11 In addition, solar intensity naturally varies with time and geographical location and these variations …
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 [].

An equivalent circuit model of an ideal solar cell''s p–n junction uses an ideal current source (whose photogenerated current increases with light intensity) in parallel with a diode (whose current represents recombination losses). To account for resistive losses, a shunt resistance and a series resistance are added as lumped elements. The resulting output current equals the photogenerated curr…
