Thin-film concentrator solar cells, such as the 21.5% efficient Cu (In, Ga)Se2 cell, are described in various studies. For instance, Ward et al. (2002), and Schmid et al.

On the right, a micro-concentrator system with N2 miniaturized solar cells and respective increase (arrow up) or decrease (arrow down) of relevant characteristic parameters. On the other hand, downscaling CPV to the micro-scale also opens new routes for thin-film solar cells.
In CZTS thin-film solar cells, the CZTS layer acts as a p-type region. Absorption of light by CZTS material creates electron–hole pairs, which get separated by the junction electric field. Several improvements have been made on the structural design of the CZTS solar cell from time to time, to enhance the overall efficiency (Fig. 6).
When compared to Silicon cells, the absorber layer of thin-film solar cells is much smaller, measuring between one and two micrometers. And because of the thinness, it faces the problem of absorbing the maximum amount of incident photons. Several light-trapping methods are and can be implemented in the CZTS solar cells to resolve the issue.
Most high-concentration systems are point-focus, i.e. an array of 3D designs produce concentrated spots on the solar cells, often the image of the light source (the Sun).
However, with recent advancements, thin film has become the preferred design for solar cells because of several upper hands it proved over the thick cells. CIGS (Copper Indium Gallium Diselenide) and CdS (Cadmium Selenide) have shown tremendous performances in the thin-film sector.
