Solar energy harvester based on optical rectenna, efficiency factor better that 50%The world problem that energy sources like coal, oil and gas are finite and spoiling ecology. Solar is a tremendous source of renewable and clean energy. Silicon monocrystal solar cell efficiency factor is 20%.47% of energy goes for heating solar cell, this effects to reduce efficiency factor. So we collect only small part of solar energy, that is 23 000 TWy. Especially in deserts.

New strategy for local diffusion of dopants in crystalline silicon A new methodology to replace conventional diffusion processes has been developed and patented. This simple procedure offers a wide versatility, since it allows the creation of locally doped regions without photolithography steps while simultaneously reducing the global thermal budget of the emitter creation process. The potential of the method has been already confirmed for silicon solar cell applications. Partners to further develop the technology and/or to establish commercial agreements along with technical cooperation are sought.

Photo-thermoelectric cell for the conversion of thermal energy into electricity Photo-thermoelectric cell for the conversion of thermal energy into electricity The Instituto de Ciencias de Materiales de Madrid (ICMM-CSIC) has developed a photo-thermoelectric cell with spectral selectivity to visible and infrared lights. If the cell is part of a thermoelectric generator, the device allows the conversion of the heat produced by incident radiation into electrical energy, due to the temperature difference established in the cell. This technology can also be used to take advantage of the residual heat of machines or electrical circuits. Industrial partners from the energy industry are being sought to collaborate through a patent license agreement. An offer for Patent Licensing

Organic derivatives for the manufacture of electronic devices CSIC have developed organic derivatives, low cost, with possibility of modifying its molecular structure, including different substitutions, improving the properties of electronic semiconductor. These molecules present not only interesting electronic properties which make them active for the manufacture of solar cells, specifically organic photovoltaic cells, but also an intense blue color which allows it so be used as a dye in the textile industry. Industrial partners from the energy, electronic and textile are being sought to collaborate through a patent licence agreement. An offer for Patent Licensing

Solar driven absorption cycle for space heating and cooling The invention relates to a new solar thermally driven system that meets the heating and cooling demands of buildings. The system consists of a reversible absorption cycle which operates as a single effect absorption cycle in the cooling mode and as a heat transformer in the heating mode. Components of both cycles are the same, only the flow direction inside the system changes. In thermally driven systems, solar thermal collectors convert solar energy into thermal heat which can be used to run a thermally-activated device. Different types of thermally driven systems are available on the market, but among them, absorption systems are the most mature technology and are commercially available. The thermal collectors mostly used in solar absorption installations are flat plate or evacuated tubes. These thermal collectors produce hot water to drive the absorption machine in summer and produce chilled water. However, the hot water temperature obtained in winter with these solar collectors is too low to directly feed conventional heating systems but also is too low to drive the absorption machine in order to produce a higher temperature water stream to feed the heating system. So, in winter the hot water produced in the thermal collectors is heated up in a boiler before to feed the heating units. The invention proposes a new reversible solar driven absorption machine that in summer it would work as an absorption chiller, as the machines that we can find on the market today, but in winter it would work as a heat transformer. As heat transformer the absorption machine cycle can be driven with a heat source temperature of 40 °C to produce hot water at 60°C at an ambient temperature of 0°C. Furthermore, the lower the ambient temperature, the lower the activation temperature of the machine and higher the machine heating power. Components of both cycles are the same, only the flow direction inside the system and the connection with external devices changes. To allow the reversibility of the equipment and its operation in winter a new working pair, ammonia/lithium nitrate, has been selected because no rectifier is required and it does not present problems of refrigerant freezing at low condensing temperatures when the cycle operates as a heat transformer.
