Photovoltaic Cells – solar cells, working principle, I/U
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.

The results of the second World Photovoltaic Scale recalibration
The World Photovoltaic Scale (WPVS) is used as a worldwide reference value for terrestrial PV performance measurements of I/sub STC/, the short-circuit current under standard test conditions. The WPVS has already been established in 1997 based on an international comparison where a set of 20 transfer/travelling standards were circulated between 11 national laboratories.

Enabling high-performance, centimeter-scale organic solar cells
There are several challenges remaining in upscaling OSCs from a lab-scale area of <5 mm 2 to a centimeter-scale sub-cell or a typical 100–400 cm 2 mini-module. 14–16 For an individual cell, a large cell width tends to create significantly increased resistance for charge extraction, whereas a smaller width of sub-cells will cause lower geometrical fill factor of

The Value of Efficiency in Photovoltaics
In this paper, we introduce the value of efficiency (VOE), a metric that determines the maximum allowable cost for an innovation to improve the levelized cost of electricity (LCOE). We then use this metric to analyze trends. Looking at historical data, we find that the VOE has declined rapidly in the past.
