![]() In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. The separate extraction of those carriers to an external circuit.The separation of charge carriers of opposite types.The absorption of light, generating excitons ( bound electron- hole pairs), unbound electron-hole pairs (via excitons), or plasmons. ![]() The operation of a photovoltaic (PV) cell requires three basic attributes: In addition to producing energy, they can be used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity. Solar cells are described as being photovoltaic, irrespective of whether the source is sunlight or an artificial light. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 volts to 0.6volts. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as solar panels. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. ![]() A solar cell, or photovoltaic cell, is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. ![]()
