Statistical analyses on Si microwire solar cells

In this data, the statistical analyses of silicon microwire (SiMW) solar cells are presented for the research article entitled "Electrical and optical properties of Si microwire solar cells" (H.-S. Kim, D. B. Patel, H. Kim, M. Patel, K. R. Chauhan, W. Park, and J. Kim) [1]. This article shows the statistical analyses on performances of the various SiMW solar cells. The accuracy of solar cell pa...

Novel high-efficiency crystalline-silicon-based compound heterojunction solar cells: HCT (heterojunction with compound thin-layer).

With an amorphous silicon (a-Si:H)/crystalline silicon (c-Si) heterojunction structure, the heterojunction with intrinsic thin-layer (HIT) solar cell has become one of the most promising technologies for c-Si based solar cells. By replacing a-Si:H thin films with appropriate compound semiconductors, we propose novel heterojunction structures which allow c-Si heterojunction solar cells to posses...

Role of majority and minority carrier barriers silicon/organic hybrid heterojunction solar cells.

A hybrid approach to solar cells is demonstrated in which a silicon p-n junction, used in conventional silicon-based photovoltaics, is replaced by a room-temperature fabricated silicon/organic heterojunction. The unique advantage of silicon/organic heterojunction is that it exploits the cost advantage of organic semiconductors and the performance advantages of silicon to enable potentially low-...

Valence band alignment and hole transport in amorphous/crystalline silicon heterojunction solar cells

To investigate the hole transport across amorphous/crystalline silicon heterojunctions, solar cells with varying band offsets were fabricated using amorphous silicon suboxide films. The suboxides enable good passivation if covered by a doped amorphous silicon layer. Increasing valence band offsets yield rising hole transport barriers and reduced device effciencies. Carrier transport by thermal ...
