The PV cell, often referred to as a solar cell, is the basic building block of any solar plant. The design of these cells is paramount, as they capture and convert sunlight into electricity. Typically composed of semiconductors like silicon, these cells function by absorbing photons from sunlight, exciting electrons, and creating an electrical ...
The sub-cells in multi-junction solar cells are connected in series; the sub-cell with the greatest radiation degradation degrades the efficiency of the multi-junction solar cell. To improve the radiation resistance of (In)GaAs sub-cells, measures such as reducing the dopant concentration, decreasing the thickness of the base region, etc., can ...
Ultimately the size, weight, and volume of smaller satellites may be the determining factor in choosing solar cell technology, rather than solar cell efficiency. Being a life-limiting component on most spacecraft, the EOL performance at operating temperature is critical in evaluating their performance.

As the negative charge (light generated electrons) is trapped in one side and positive charge (light generated holes) is trapped in opposite side of a cell, there will be a potential difference between these two sides of the cell. This potential difference is typically 0.5 V. This is how a photovoltaic cells or solar cells produce potential ...
The introduction of these materials has led to several categories of solution-processable OSC depending on the composition of the photoactive layer, …
