“…The laser pulse energy was 150 mJ on the window. Details of the chemical structure of the starting precursor (C 10 H 16 O), the C 10 H 16 O burning system and the target preparation method have been described elsewhere [4]. In brief, C 10 H 16 O was burnt in a quartz tube and the soot deposited along the walls of the tube was collected, dried in the oven for an hour and pressed into pellets in order to use them as targets in PLD.…”

“…Graphite is the most common solid target used in physical vapour deposition methods for carbon films. We have been working on semiconducting carbon, obtained from camphor (C 10 H 16 O), a natural source [1,4,5]. The starting precursor, C 10 H 16 O, has both sp 2 and sp 3 hybridized bonds while graphite has 100% sp 2 bonded structure.…”

“…PLD system is a very efficient method to deposit high quality carbon thin film. Successful doping of P in carbon thin film using PLD has already been reported [4]. However, in spite of being a promising material for optoelectronic devices, up to now the junction characteristics of carbon-based heterostructure remain unclear.…”

Solar cells with high efficiency and low price have long been desired, however, the commercially available solar cells are still expensive and the efficiencies of them are not high enough yet. A tandem solar cell was fabricated to develop a high-efficiency solar cell, and amorphous carbon solar cells were fabricated to develop a low-price solar cell.An AlGaAs/Si tandem solar cell was successfully fabricated by heteroepitaxial growth of AlGaAs on Si substrate. At first, a p-n junction was formed in Si substrate by the impurity diffusion method. Then, an AlGaAs p-n junction was grown by MOCVD. Since the AlGaAs p-n junction has a graded band gap emitter, the photo-excited minority carriers can be collected efficiently. The energy conversion efficiency of AlGaAs/Si tandem solar cell was 21.4% (AM0) in spite of large lattice mismatch and difference in thermal expansion coefficients between AlGaAs and Si. Solar cells were fabricated by using amorphous carbon films deposited by Ion Beam Sputtering and Pulse Laser Deposition (PLD). The highest efficiency of 1.82% (AM0) was attained with a-C(IBS)/p-C(pyrolysis)/p-Si structure. Solar cells using a-C:H were also fabricated by PLD and Plasma CVD, and the efficiencies of them were 2.1% (AM1.5) and 0.04% (AM0), respectively.Other research activities on solar cells in Nagoya Institute of Technology are briefly mentioned. q

“…Previously, phosphorus-doped carbon films were mainly fabricated by vapor deposition techniques, such as plasma immersion ion implantation and deposition [13], capacitively coupled radio frequency plasma deposition [14], filtered cathodic arc method [10], pulsed laser deposition [15], etc. However, the process using electrochemical deposition was particularly interesting.…”
