OLEDs in Lighting: Technical Challenges and Opportunities
A potential limitation to using OLEDs for lighting is their low intensity emission per area, leading to high cost. We examine the fundamental limits to OLED brightness. Limitations to be considered include: thermal effects, triplet and singlet annihilation, exciton-polariton annihilation and injection and outcoupling. We consider the differences between single element and stacked devices in overcoming these fundamental problems. We also discuss the possibility for the use of organics in lasing applications, following recent advances in exciton management.

Mass Producible PERC Cells With Over 20% Conversion Efficiency
Recent revitalization of passivated emitter and rear cell (PERC) concept in the silicon PV industry has resulted in solar energy conversion efficiency higher than 20% being reached on p-type solar grade single-crystalline silicon (mono-Si) wafers during the past few years, thanks to the technological advance in utilizing aluminum oxide for silicon surface passivation. The industry version of PERC cells can be mass produced nowadays on the existing conventional BSF cell manufacturing platform with moderate retrofitting using p-type Si wafers grown by Czochralski method without special quality requirement. Moreover, by applying the same PERC approach in combination with some light trapping technique to the cells using polycrystalline silicon (multi-Si) wafers produced by seeded directional solidification method, an averaged 20% conversion efficiency for multi-Si solar cells can also be practically achieved.

Challenges and Opportunities for Cost-Competitive Concentrating Solar Power
Concentrating solar power (CSP) technologies use mirrors to focus sun’s rays onto an absorber, where the photons are converted to heat that’s ultimately transferred to the working fluid of a turbine to generate electricity. The ability of CSP to incorporate simple and efficient thermal energy storage is a principal advantage of the technology. Widespread adoption of this technology calls for steep cost reductions, which is a primary challenge being addressed through several world-wide efforts. The talk will focus on the technical challenges and opportunities for innovation and cost reduction, for achieving cost-competitive concentrating solar power.

Storage Requirements in an European Scenario of Electricity Generation from 100% Renewable Sources
We investigated the relationship of power plant mix and required energy storage capacity with a computer model based on global weather data. We focus on energy storage requirements of an electricity supply for Europe by wind and solar power (PV). The minimum required energy storage capacity for a 100% renewable (wind and PV) electricity supply occurs at »30% wind and »70% PV installed capacity. A transition of today’s European electricity supply to a 100% renewable scenario would rise the required energy storage capacity exponentially to about 150 TWh (3.8% of the annual electricity demand). However the installation of excess wind and PV power plant capacity is shown to drastically reduce the required energy storage. For instance 10% excess capacity cut the required storage capacity in half, higher excess capacities lead to further, significant reduction of storage requirements. Furthermore, storage can be separated into daily (short term) storage and seasonal (long term) storage. Seasonal storage capacity has to be about two orders of magnitude larger than storage for the daily cycle, however, the annual sum of stored energy is nearly equal for both types of storage. In summary, an electricity supply by only wind and PV power is shown to be perfectly feasible with respect to the required energy storage capacity and required land area for power plants, and offers competitive electricity generating cost.
