Improvement of the efficiency of the furnace in terms of its design. The recycling of PV modules for silicon production can also contribute to reducing energy consumption and thus CO 2 emissions, depending on how much energy is required to process the recycled silicon material to the appropriate quality for wafers [2, 9].
The development of silicon-based photovoltaic (PV) cells began with the discovery of the photovoltaic effect by Alexandre-Edmond Becquerel in 1839.
The emissivity of the non-encapsulated c-Si solar cell was determined to be 75% in the MIR range, and the emission of free charge carriers dominates in the highly doped emitter and back surface layers of the array. Both effects are enhanced by the improved optical connectivity resulting from the texture of the front surface.
The metal contacts play a key role in the production of highly efficient and cost-effective crystalline Si PV cells. For both polarities, electrons and holes, the metal contacts must conduct charge carriers at low ohmic contact resistance to the corresponding silicon surfaces .
One of the most important improvements was the introduction of silicon purification techniques that resulted in a higher quality semiconductor material with fewer impurities, which had a direct impact on increasing the efficiency of PV cells.
Losses Due to Degradation A lesser-known phenomenon that affects a large part of the crystalline silicon cell market is light-induced degradation (LID). In simple terms, this is the deterioration of solar cells due to solar radiation in the first few days after installation. This may result in 0.5% to 1.5% in losses.
