Multijunction Semiconductor Solar Cell

A monolithic semiconductor photovoltaic solar cell comprising a plurality of subcells disposed in series on an electrically conductive substrate. At least one subcell of the plurality of subcells includes an epitaxially grown self-assembled quantum dot material. The subcells are electrically connected via tunnel junctions. Each of the subcells has an effective bandgap energy. The subcells are disposed in order of increasing effective bangap energy, with the subcell having the lowest effective bandgap energy being closest to the substrate. In certain cases, each subcell is designed to absorb a substantially same amount of solar photons.  Read More

Method For Desalinating Saltwater

In order to desalinate saltwater that is contained within a product chamber, a drive cell is used to generate a drive voltage. The product chamber has a desalination voltage such that when a sufficient voltage is applied to the product chamber, anions and cations migrate out of the product chamber, thereby desalinating the water. The sufficient voltage, which includes the drive voltage and which is equal to or greater than the desalination voltage, is applied to the product chamber, consequently effecting desalination. Beneficially, concentration difference energy can be generated using a concentrated solution, which can be generated using, for example, solar energy.  Read More

App for Calendar Sharing & Scheduling

When a meeting is to be scheduled between two or more participants, the organizing participant enters an identification of the participants and requests a time suggestion. In response to the request, information relating to the availability and/or preferences of each participant is gathered from one or more databases and processed centrally in a remote server to determine a block of time during which all the participants are commonly free. The block of time is pushed to a user interface for display. If the organizing user selects the block of time, a meeting request may be sent to the participants to confirm the meeting. Read More
