Abstract: The present invention relates to a photosensitive organic semiconductor composition comprising an organic p-type semiconductor pigment with a p-type conducting polymer, wherein the ionization potentials of the organic p-type semiconductor pigment and the p-type conducting polymer are nominally equivalent and a photosensitive organic semiconductor composition comprising an organic n-type semiconductor pigment with an n-type conducting polymer, wherein the electron affinities of the organic semiconductor pigment and the conducting polymer are nominally equivalent. The present invention also relates to a p/n heterojunction utilizing the photosensitive organic semiconductor compositions.

Abstract: A known charge card billing system communicates with an investment broker system, wherein the investment broker system includes an instruction arrangement database, payment hierarchy and an investment account. An interested cardholder suitably appoints the charge card administrator as a processing agent to collect and promptly remit the cardholder's voluntary, periodic payments for investment into preselected investment products, such as, for example, mutual fund shares, fixed annuities, variable annuities, CDs, insurance, certificates, equities and/or the like. The billing system distributes a billing statement at the end of each month, wherein the statement includes all of the charges for that month and a reminder to remit an additional dollar amount for the preselected investments. The cardholder then sends a single payment for the charges and the investments to the charge card administrator.
