It is quite possible for a module with a higher value for  STC than another

module under standard test conditions to have the lower outdoor efficiency value  RRC.

For improving F.F., you need to measure Rs,Rp accurately in different irradiance intensity without any guesswork.

1. Scope and object

This standard is referred to by other IEC standards in which class requirements are laid down for the use of solar simulators. Solar simulators for irradiance exposure should at least fulfil class CCC requirements where the third letter is related to long term instability. In the case of use for PV performance measurements, classification CBA is demanded where the third letter is related to the short term instability

Results of the c-Si Round Robin

GSI&HTTR2009.1128/35

The spread for reported Pmax values lies all in the range ±2%. The ISAAC institute confirmed so its comparability with the other laboratories.

The next round-robin test will include as well indoor performance measurements at low irradiance anddifferent module temperatures, insofar as such information is required for energy rating. The final aimof the project is to establish the comparability of a PMAX of ±1% between the test laboratories.

結論 3:No sweep speed dependencies have been observed at 2ms.

The final results and the inter-comparison of the different laboratories will be published in the next annual report.

Following preliminary results can be presented:1. A good repeatability of measurements was observed for all modules when stored under dar

k/ambient temperature conditions.2. Only the CIS modules were influenced by the 1 hour outdoor exposure. An increase in maxim

um power was observed.3. No sweep speed dependencies have been observed at 2ms.4. Some technologies showed a non-linear behaviour of Pmax and Isc versus temperature. This

effect was especially pronounced for multi-junction devices.5. The STC power of CIS modules tended to relax during the transport into the dark room and c

ooling of the module to ambient temperature. An indoor light pre-conditioning of 30-90 minutes at 25W/m² was needed to stabilise the module before outdoor exposure, whereas the time reduced to 5-60 minutes after the 1 hour of outdoor exposure.

如圖 8 所示， Flash 時 cell 的光電壓與照射光本身的光電壓圖。在波形初始的 Delay time 兩者相距約 0.02ms 而在波型末端的 falling time 兩者相距約為 0.12ms 。我們同意【台大】所提出的說法。因為每種材質對光譜的吸收反應不同。因此圖 8 所反應的不同材質對照光本身的光電壓會有所差距；但圖 8 所量測的時間為 Delay time(0.02ms) 與 Endeas 擷取的 2ms時間相比，兩者差距百倍，此差距微乎其微對量測結果不受影響。

Endeas Flash Type 是屬於 Pulsed light decaying，從完全未受光狀態，到擷取 1000W/m2幅照時， a-Si待測物已受到超過幅照 3000W/m ，時間為 8.5ms的幅照，相對已達飽和，可開始做 I-V量測。

32/35

GSI&HTTR2009.11

Response Delay Time 對於 IV 曲線量測不具明顯的影響Thin-film模組對於幅照的Delay Time，從完全未受光，到飽和穩定輸出光電流，反應時間約在 1ms左右。

Indoor & Outdoor 量測比較

對於 Thin-film各種材質，2ms之 Pulsed light, decaying，與戶外量測以太陽光為光源， I-V量測結果頗為一致。

Endeas Solar Simulator系統可分為三大部分：1.AAA Class Sun Simulator 符合 IEC 60904-9

2.I-V量測系統

3.符合 IEC 60891規範修正軟體

對於待測物 Response Time對於量測的影響，遠不及於光譜匹配、非均勻性、重複穩定性，所造成的量測誤差。這才是量測設備為何需要 AAA等級模擬器之原因。
