Abstract
A method of making an energy conversion device includes forming a plurality of pores within a substrate and forming a junction region within each of the plurality of pores. Each of the junction regions has a depletion region and each of the plurality of pores defines an opening size in the substrate and a spacing from adjacent pores so that the depletion regions of each of the pores is at least substantially in contact with the depletion region of the pores which are adjacent.

A method of making an energy conversion device, the method comprising:
- forming a plurality of pores within a substrate;
- forming a junction region within each of the plurality of pores, each of the junction regions has a depletion region and each of the plurality of pores defines an opening size in the substrate and a spacing from adjacent pores so that the depletion regions of each of the pores is at least substantially in contact with the depletion region of the pores which are adjacent;
- forming a first portion of one or more side walls of at least one of the pores with a declination angle of less than about fifty-five degrees;
- and
- forming a second portion of the one or more side walls of the at least one pore with a declination angle greater than about fifty-five degrees.
A method of making an energy conversion device, the method comprising:
- providing a substrate;
- forming a plurality of junction regions in the substrate, wherein a first portion of at least one of the junction regions has a declination angle of greater than about fifty-five degrees relative to a second portion of each of the junction regions, wherein each of the junction regions has a depletion region and each of the junction regions is spaced from the adjacent junction regions so that the depletion regions are at least substantially in contact with each other;
- forming a first section of at least one of the plurality of junction regions with a declination angle less than about fifty-five degrees relative to the second portion of the at least one of the junction regions;
- and
- forming a second section of the at least one of the plurality of junction regions with a declination angle greater than about fifty-five degrees relative to the second portion of the at least one of the junction regions.
