  • Three Dimensionally Structured Thin Film Photovoltaic Devices with Self-Aligned Back Contacts
    Publication number: 20110041899
    Abstract: A process for producing three dimensionally structured thin film photovoltaic devices with self-aligned back contacts. The photovoltaic device is constructed using electrodeposition on micrometer-scale interdigitated electrodes on an insulating substrate. During fabrication, these interdigitated electrodes serve as the active electrodes for deposition of materials including semiconductors. After fabrication, these interdigitated electrodes serve as back contacts for carrier collection when the device is in use. The process can be used to fabricate homojunction, heterojunction and multijunction photovoltaic devices.
