CHEETAH knowledge Exchange Portal is an integral part of CHEETAH project web site powered and developed by DTE unit of ENEA ©2014 - 2018 with support of all CHEETAH Partners. Starting from early 2018, CHEETAH KEP moved its first steps to became EERA Knowledge Exchange Platform for PV Technology (KEPT-PV). A new name for the previous platform characterizing our will to serve better and more efficiently in Knowledge Exchange a wider European and International PV RTD community.

Technical Info



In 2010 the University of Milano-Bicocca (UNIMIB) founded the MIB-SOLAR Center to enhance and promote the already well established UNIMIB research activities in the field of PV technologies. The distinctive feature of MIB-SOLAR is the ability to offer research and development all the way, from the computational design of the material to the preparation and characterization of the device at pre-competitive level, with a close interaction between academia and industry, working from crystalline silicon to inorganic, organic and hybrid thin film devices


The laboratory offers the following equipments:

  1. fully equipped laboratories for synthesis (including glove-box reactions, microwave, etc.) and characterization (including multinuclear NMR, absorption and emission spectroscopy, ATR-IR, TGA, DSC, GC-MS, etc.) of organic, inorganic, and polymeric materials;
  2. fully equipped laboratories for electrochemical synthesis and investigation;
  3. study of chemical, thermal, and photochemical short- and long-term stability;
  4. fabrication of thin film CIGS solar cells by a technique hybrid between sputtering and evaporation
  5. fabrication of DSCs and organic/polymeric cells (glove-boxes);
  6. solar simulators for small cells (2×2”) and modules (6×6″) and Keithley digital source meters for current/voltage measurements
  7. fully integrated system for EQE and IQE measurements;
  8. Scanning Electron Microscopy (SEM) equipped with EDX and EBIC; 77-300 K;
  9. large variety of spectroscopic tehniques for characterization of materials in solution, solid-state and in devices;
  10. Light Beam Induced Current (LBIC);
  11. sputter, evaporator, plasma and ozone cleaning;
  12. resistivity and Hall measurements
  13. Quasi Steady-State Photoconductance Decay (QSSPC) for lifetime testing;
  14. ageing of solar cells under thermal stress and light soaking



The access will be allowed with technical and scientific assistance from UNIMIB
