6 FAQs about [Spherical concentrating solar cell]

What is a spherical Si solar cell?

The theoretical estimation of an attainable Jsc of a spherical Si solar cell can be obtained from the integration of a reflection over the sphere surface and standard solar energy spectrum as a function of wavelengths. Here, the cell area is defined as the projection area of a sphere.

How do spherical solar cells work?

The spherical solar cells are shown to be able to collect and harvest sunlight three-dimensionally. More specifically, the spherical solar cell acts as a sun-tracking flat cell with the same ground area, and horizontal and vertical flat cells with twice the ground area in terms of the diffuse and reflected beam, respectively.

Can spherical Si solar cells with semi-concentration reflector system perform better?

What is JSC of a spherical Si solar cell?

Here, the cell area is defined as the projection area of a sphere. If internal quantum efficiencies in the wavelength range 300–1150 nm are assumed to be unity, Jsc of spherical Si solar cell without anti-reflective coating is calculated to be 26.2 mA/cm 2, while that of a conventional flat Si solar cell with a flat surface is 28.5 mA/cm 2.
