Book Description
The energy gap of unhydrogenated amorphous boron is approximately 1.35 eV and therefore the theoretical maximum efficiency for amorphous boron solar cells is approximately 25%. However, in exact analogy with the situation previously existing for amorphous silicon, amorphous boron, without hydrogenation, has poor semiconducting properties due to defect states in the band gap. Large area amorphous boron films can be readily produced by either chemical vapor deposition or pyrolysis of diborane or boron tribromide. Such films do not contain more than minute quantities of hydrogen, however, due to the high (1000°C) pyrolysis temperatures required. The substrate temperature during glow discharge decomposition methods, however, can be independently controlled. The decomposition of diborane in a glow discharge has been used to dope amorphous silicon with boron. The decomposition of diborane and of boron tribromide in hydrogen to produce thin films can reasonably be expected to result in amorphous boron thin films containing substantial quantities of hydrogen. If the effect of hydrogen in amorphous boron is similar to that of hydrogen in silicon, then hydrogenated amorphous boron thin films resulting from glow discharge decomposition of gaseous boron compounds could have very great potential as a solar cell material. Initial work and research plans are outlined.

Book Description
The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.
