Cadmium telluride (CdTe) solar cells contain thin-film layers of cadmium telluride materials as a semiconductor to convert absorbed sunlight and hence generate electricity.
Solar energy has emerged as a promising renewable solution, with cadmium telluride (CdTe) solar cells leading the way due to their high efficiency and cost-effectiveness. This study examines the performance of CdTe solar cells enhanced by incorporating silicon thin films (20-40 nm) fabricated via a sol-gel process.
The Cadmium Telluride (CdTe) solar technology was first introduced in 1972 when Bonnet and Rabenhorst designed the CdS/CdTe heterojunction that allowed the manufacturing of CdTe solar cells. At first, CdTe panels achieved a 6% efficiency, but the efficiency has tripled to this day.
Cadmium telluride PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems.
Cadmium telluride photovoltaic cells have negative impacts on both workers and the ecosystem. When inhaled or ingested the materials of CdTe cells are considered to be both toxic and carcinogenic by the US Occupational Safety and Health Administration.
Cadmium Telluride thin film solar cell is very suitable for building integrated photovoltaics due to its high efficiency and excellent stability. To further reduce the production costs, relieve the scarcity of Tellurium, and apply in building integrated photovoltaics, ultra-thin CdTe photovoltaic technology has been developed.
The structural properties of CdTe at 300K are summarized in Table 3.1.2. Table 3.1.2. Structural properties of cadmium telluride at 300K (Nowshad, 2001). The stoichiometric ratio of CdTe is typically 1:1 and melts near 1092°C. However, CdTe melts at a lower temperature if the material composition deviates.
