Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

Customer ServiceNREL Best Research-Cell Efficiencies chart . Photovoltaic cells can be categorized by four main generations: first, second, third, and fourth generation. The details of each are discussed in the next section. 2. Photovoltaic Cell Generations In the past decade, photovoltaics have become a major contributor to the ongoing energy transition.
This deterioration compromises the lifespan of PV cells as it increases the difficulty of dissipating heat. Experimental tests of two degradation types (formation of cracks and formation of bubbles) were carried out on different photovoltaic technologies (c-Si, a-Si, CIGS and organic perovskite cells).
Therefore, the accuracy of this fitting model was proven as it portrays, simultaneously, the behavior of photovoltaic cells in the absence and presence of degradation. The crystalline silicon cell is a rigid structure, and the remaining studied technologies are flexible.
Between 1992 and 2023, the worldwide usage of photovoltaics (PV) increased exponentially. During this period, it evolved from a niche market of small-scale applications to a mainstream electricity source. From 2016-2022 it has seen an annual capacity and production growth rate of around 26%- doubling approximately every three years.
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.
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.
