DIX HILLS, NY - (MARKET WIRE) - Solar Thin Films, Inc. (OTC BB:SLTN.OB - News) today announced that it has acquired a 15% equity interest in China-based CG Solar (previously Weihai BlueStar Photovoltaic Co. Ltd.) in exchange for $1,500,000. As noted in Solar Thin Film's 8-K filing on 2/25/08, the acquisition was completed through two separate transactions.

On January 31, 2007, Solar Thin Films, Inc. (the "Company") entered into an Assignment and Assumption Agreement of Joint Venture Contract with Renewable Energy Solutions, Inc. ("RESI"), pursuant to which the Company agreed to transfer the sum of $500,000 on behalf of RESI to CG Solar in exchange for a 5% equity interest in CG Solar.

On January 31, 2007, the Company entered into an Agreement for the Plan and Sale of Equity Interest with Terra Solar, pursuant to which the Company agreed to transfer the sum of $1,000,000 to Terra Solar in exchange for the acquisition of a 10% equity interest in CG Solar.

The completion of both transactions has received all requisite approvals, including approval by the board of directors of China Solar Energy Holdings Limited, the parent company of Terra Solar.

The transactions, and acquisition of 15% of CG Solar, are consistent with the Company's strategy to take an equity interest, and purchase or marketing rights, in the operations of "turnkey" module manufacturing customers. Earlier the Company announced that it had entered into a marketing agreement with CG Solar providing certain rights to market their modules in North America and Europe.
