<p>The effective area of a solar cell unit may be enlarged or increased considerably relative to its physical area by providing its exposed surface layer with a periodic structure or pattern, by which a local field is generated, a so-called Hartree harmonics field. The periodic structure is preferably a grating structure or pattern, and by orienting the solar cell edgewise so that the sunlight is grazing rather than oblique or directly perpendicular to the surface, its response factor may be increased up to a factor 11 theoretically.</p> |
