17、MICONDUCTOR DEVICES FOR ENERGY HARVESTING AND GENERATION Part 2: Thermo power based thermoelectric energy harvesting FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Commi
18、ttees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Availa
19、ble Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental orga
20、nizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical
21、matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC Nat
22、ional Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity,
23、 IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC it
24、self does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that
25、 they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any natu
26、re whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
27、 publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Internation

The electrical resistivity and the thermopower shall be measured in order to define the thermoelectric properties of the materials used for fabrication of thermoelectric devices. Generally t
42、o measure these values the materials should be investigated under temperature from between 3 K and 300 K. There are two types of measuring methods for thermo-power measurement. The first is the integral method and the other is the differential method. In case of measuring the electrical conductance
43、the electrical resistivity is to be measured and the reciprocal number of the measured value is to be used.A four-point proof method is typically used in electrical resistivity. When this method is used, the total voltage drop can be measured by the sum of resistive voltage and Seebeck voltage. To o

In addition, the sample will be prepared of a wire type which has a diameter under 200 m and thin films which have been deposited onto the silicon su

The generated voltage change between the reference material and sample mater

The third thermocouple can be attached to the hot junction of the reference and sample wire to measure the temperature of the junctio
