Consider the graded band gap pn junction shown in Fig. 1.We assume that this cell is defect free, and hence the carriers'' mobilities and diffusion lengths are very large with respect to the cell length H.Under solar irradiation, a voltage V is developed across the junction. The electron and hole quasi-Fermi levels split by qV.Therefore, the electron and hole
Depending on the materials used in the manufacturing process of the panels, PV technologies can be broadly classified into three generations: crystalline silicon (c-Si), thin-film-based, and other novel solar cell technologies under development (Xu et al., 2018).Over the years, c-Si solar cells have remained the dominant trend due to their high efficiency and high
CdTe solar cells have been identified as the best candidate for PV technology. CdTe solar cells can absorb a huge amount of sunlight due to their high absorption coefficient and direct band gap of 1.45 eV [26]. CZTS is a quaternary compound with a band gap of 1.4–1.5 eV and an absorption coefficient of 1.0 x10 4 cm −1 [27].

It is not surprising, on the other hand, that a lot of effort has been going on and is still going into the search for new materials. Requirements for the ideal solar cell material are: (1) band gap between 1.1 and 1.7 eV (2); direct band structure (3); consisting of readily available, non-toxic materials; (4) easy, reproducible deposition technique, suitable for large area

The factors that influence the cost of diffused solar PV manufacturing supply chains relative to concentrated ones in China and Southeast Asia are first labor cost and then interest burden. Here the interest burden represents a potential increase in the cost of capital for investment.
Consequently, states must cooperate to coordinate finance, subsidies, incentives, and trade barriers for solar PV manufacturing. This international cooperation is essential to diversify supply chains so that it will minimize increased costs, leverage scale, and increase innovation and resilience while reducing market uncertainty. Introduction
Given the undergoing energy transition, any supply chain concentrated to this degree brings vulnerabilities from potential shocks. Like-minded countries consequently look to reduce the risks from such concentration. National governments have taken efforts to spur domestic manufacturing of solar PV to reduce supply chain dependencies.
The cost difference (final module cost) between concentrated and diffuse solar PV supply chains is sensitive to labor costs, interest burden, and electricity cost. Costs are final module cost.
Absent subsidies, fully integrating domestic supply chains of solar photovoltaics will come at substantial cost to some economies (Figure 3). China and Southeast Asia remain the most cost competitive reflecting the current concentration of solar PV manufacturing in these regions.
