A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.
Once the equation was determined, it was used to compensate the sensor output. On average, the accuracy improvement using compensation is ±2˚C for all tested devices over the operating temperature range. The compensation also improves the wide temperature accuracy specification limits at hot and cold temperature extremes.
$begingroup$ It''s a bit more complicated than that. The problem is that it takes a certain amount of time Δt₁ for plastic to reach the temperature of its environment (the melting zone). That heat transfer is not instantaneous. Furthermore, there is a certain amount of time Δt₂ that the plastic can spend in the melting zone before it is extruded. As you increase throughput, …

Another quick fix would be to substitute a BPW34 for the CdS photo-cell. Reverse biased would be the most immune to temperature swings, but measuring the open-circuit voltage gives the best dynamic range. (and with a >1 mA photo-current under "full-sun" you shouldn''t need to change the load resistor much) Lawson
