Thick wafer-silicon is the dominant solar cell technology. It is of great interest to develop ultra-thin solar cells that can reduce materials usage, but still achieve acceptable performance and high solar absorption. Accordingly, we developed a highly absorbing ultra-thin crystalline Si based solar cell architecture using periodically patterned front and …

The solar cell is thus an n + pp + structure, all made of crystalline silicon (homojunction solar cell) with light entering from the n + side. At the front (n + region), the donor concentration N D falls steeply from more than 10 20 cm −3 at the surface to values below N A in a depth of less than 1 μm.
Carrier-selective contacts based on inorganic materials (e.g., silicon layers and metal oxides) have been intensively investigated for efficient crystalline silicon (c-Si) photovoltaics. Compared to the vacuum deposition process for inorganic films, organic semiconductors offer a simplified and low-cost processing.
Crystalline silicon
The most widely used material for photovoltaic (PV) energy conversion is crystalline silicon (Si). A crystalline Si pn junction solar cell consists of a relatively small n-type emitter and a much thicker p-type base (Fig. 1a) nlight enters the Si solar cell through the thin n-layer, which acts as a window and generates electron-hole pairs mainly …
