Item 1.01

Entry into a Material Definitive Agreement.

As previously reported, on March 19, 2010, Solar EnerTech Corp. (the “Company”) entered into an Exchange Agreement (the “Exchange Agreement”) with Capital Ventures International (“CVI”) whereby the Company issued a Series B-1 Convertible Note (the “Note”) to CVI with an original principal amount of $1,815,261.

On March 15, 2011, the Company received a letter from CVI alleging that a Trigger Event (as defined in the Note) has occurred, because on February 22, 2011, the Company’s common stock switched from trading on the OTCBB, the OTC Bulletin Board, to OTCQB, a new marketplace developed by the OTC Markets Group. As a result, CVI wished to accelerate all principal, interest and late charges outstanding under the Note.

On May 11, 2011, the Company and CVI entered into an Amendment to Series B-1 Convertible Note and Waiver Agreement (the “Amendment”). The Amendment provides that CVI waives all alleged Trigger Events under the Note. The Amendment also reduces the Conversion Price (as defined in the Note) from $0.15 to $0.10.

The foregoing summary of the Amendment is qualified in its entirety by the full text of the Amendment, which is incorporated herein by reference. A copy of the Amendment is filed with this Current Report on Form 8-K as Exhibit 10.1.
