In the third generation, which are multi-junction solar cells, a network of diodes is the best model and the current-voltage relations can be calculated by determining the number of series and/or parallel junctions. The parallel connected diodes are increasing the final current and the series connected diodes can increase the final voltage as well.
A key problem in the area of photovoltaic cell development is the development of methods to achieve the highest possible efficiency at the lowest possible production cost. Improving the efficiency of solar cells is possible by using effective ways to reduce the internal losses of the cell.

Second Generation of Photovoltaic Cells
The primary role of a photovoltaic cell is to receive solar radiation as pure light and transform it into electrical energy in a conversion process called the photovoltaic effect.
This was the driving force that led to the emergence of the second generation of thin film photovoltaic cells, which include CIGS. In terms of efficiency, the record value for CIGS is 23.4%, which is comparable to the best silicon cell efficiencies.
As the temperature rises, the kinetic energy of the charge carriers (electrons and holes) within the PV cell increases. Higher kinetic energy leads to more random movement of the charge carriers, which affects their ability to contribute to the cell’s electric current .
