Solar cell physics coursework. Silicon Solar Cells

First-generation solar cells are primarily fabricated from silicon wafers, including both single-crystalline and poly-crystalline silicon. In addition, Jen has patented new materials and interface chemistry that allow key layers in the tandem to be printed. How will I learn on this module? These cells capture phonons from the light by exciting electrons to travel across the semiconducting material's band gap, from the valance band VB to the conduction band CBforming electron-hole pairs.

Electronic structure: The two materials work in tandem to generate more voltage and power than can be created with either material by itself. Charge separation in nanostructured materials.

In addition, rear point contact cells have been developed so there are no metal electrodes on top preventing the reflection of sunlight. Focus will be given to silicon-based solar cells and solar cell processes, examples and calculations related to these materials.

The current SunShot initiative from the Department of Energy is to multiply the capacity by 12 times to gigawatts by Semiconductors have this band gap where electrons can be excited through the band gap into the conduction band where they can be extracted for electricity. Working together, the team hopes to be able to print a new generation of high-efficiency low-cost solar cells.

Effect of concentration on solar cell efficiency.

Gee et al. If we can understand the basic physics, chemistry and engineering of these new perovskite materials, we could enable a new era of ultra low-cost high-efficiency solar cells. Learning outcome The solar cell physics coursework gives an introduction to the application of computational methods for solar cell materials. A range of learning and teaching approaches are used in this module.

Physics of Silicon Solar Cells An ideal solar cell has a direct band gap of 1.

To support this learning journey, students are introduced to an online resource www. As previously mentioned, in single p-n junction solar cells, any photon with energy lower than the material's band gap will not be absorbed and any photon greater than the band gap will lose energy due to thermal relaxation as show in Fig. How will I be assessed?

Conclusion The use of solar concentrators on multijunction solar cells has the ability to harvest sunlight with high efficiencies at a relatively low cost without the need of relying on vast amount of semiconducting materials and land area, which is very appealing to investors.

Verbal feedback will be provided during seminar sessions.

Carrier statistics and transport. Close loops trackers use photo-sensors to provide constant feedback, resulting in accurate alignment; however, this constant feedback creates a lot of stress on the motor and can easily be affected by environmental changes or cleanliness of the sensor.

Here is a drawn band diagram of solar cell physics coursework p-n junction of a silicon solar cell showing electron-hole pairs being created by incoming photons with energies of hv and electrons being swept away to the right to be used for our electricity.

Learning outcome The course emphasizes charge separation upon photon absorption as the central process in photovoltaic devices, and will give the student an overview of mechanisms for charge separation in conventional and nanostructured materials. The fundamentals of band structure methods along with the topics treated include structural phase stability, bonding, and physical properties electrical, optical properties of materials using state of the art ab-initio calculations.

Subjects covered include, semiconductors under equilibrium conditions, direct and indirect energy bandgaps, optical absorption and electrical properties.
