  • Patent number: 10090432
    Abstract: Photoactive devices include an active region disposed between first and second electrodes and configured to absorb radiation and generate a voltage between the electrodes. The active region includes an active layer comprising a semiconductor material exhibiting a relatively low bandgap. The active layer has a front surface through which radiation enters the active layer and a relatively rougher back surface on an opposing side of the active layer. Methods of fabricating photoactive devices include the formation of such an active region and electrodes.

  • Patent number: 7921021
    Abstract: A process, system, and manufacture are provided for decreasing the amount of treatment a patient requires from a first care-giver. In at least one example, the system comprises a means for receiving a set of records, and the set of records includes at least one representing a treatment prescribed by the first care-giver, and at least one representing at least one patient characteristic. There is also a means for determining, from the set of records, independently of records relating to effectiveness of the treatment prescribed for the patient, and based on a predetermined set of screening criteria, whether a different treatment is appropriate. Further, a means is provided for generating, based on the screening, an eligibility tag associated with the patient for providing notice to the patient associated with the eligibility tag of the different treatment availability at no cost to the patient and of a financial consequence of receipt of the treatment.
