Embodiments of the invention generally provide methods for forming a silicon-based photovoltaic device. An apparatus includes an encoder for encoding picture data for at least a portion of a picture. A transmitter is also included, which has a complementary hole therethrough. The connecting part is connected to the fin elements. Use of metalP-chiral bisphospholane complexes to catalyze asymmetric transformation reactions to provide high enantiomeric excesses of formed compounds is also described.
